ABSTRACT

OBJECTIVE: Intravascular ultrasound (IVUS) is an important adjunctive tool for patients with lower extremity peripheral arterial disease (PAD) undergoing endovascular therapy (EVT). The evidence regarding the advantages of IVUS use is evolving, and recent studies have reported conflicting results. We aimed to perform a meta-analysis to evaluate the efficacy of IVUS during angiography-guided EVT for patients with PAD. METHODS: MEDLINE and EMBASE were searched through April 2023 to identify studies that investigated the outcomes of IVUS with angiography-guided EVT vs angiography-alone-guided EVT. The primary outcome was restenosis/occlusion rate; secondary outcomes were target lesion revascularization, major amputation, and mortality. RESULTS: One randomized controlled trial and 14 observational studies, largely of moderate quality, were included, yielding a total of 708,808 patients with 709,189 lesions that were treated with IVUS-guided EVT (n = 101,405) vs angiography-alone (n = 607,784). Compared with angiography alone, IVUS-guided EVT was associated with a non-significant trend towards decreased restenosis/occlusion (relative risk [RR], 0.74; 95% confidence interval [CI], 0.54-1.00; I2 = 60%). Although the risk of target lesion revascularization and mortality were comparable (RR, 0.85; 95% CI, 0.65-1.10; I2 = 70%; RR, 1.01; 95% CI, 0.79-1.28; I2 = 43%, respectively), the use of IVUS was also associated with significantly lower risk of major amputation (RR, 0.74; 95% CI, 0.67-0.82; I2 = 47%). Subgroup analysis focusing on femoropopliteal disease demonstrated significantly higher patency (RR, 0.72; 95% CI, 0.52-0.98; I2 = 73%). However, superiority with major amputation was not observed. CONCLUSIONS: IVUS-guided EVT for PAD may possibly be associated with a lower major amputation rate compared with angiography alone-guided EVT, although the difference in patency remained an insignificant trend in favor of IVUS-guided EVT. Adjunctive use of IVUS during EVT may be beneficial, and further prospective studies are warranted to delineate this relationship and the applicability of this technology in routine practice.

ABSTRACT

BACKGROUND: There is currently little evidence for transcatheter edge-to-edge mitral valve repair (TEER) for mitral regurgitation (MR) in patients with cardiogenic shock (CS). Therefore, this study investigated the characteristics and outcomes of CS patients who underwent TEER for MR. METHODS: PubMed, EMBASE were searched in July 2023. Case series and observational studies reporting clinical characteristics and outcomes in CS patients with MR who underwent TEER were included. We performed a one-group meta-analysis using a random effects model. RESULTS: A total of 4060 patients from 7 case series and 5 observational studies were included. The mean age was 68.2 (95% confidence interval [CI]: 64.1-72.2) years, and 41.4% of patients (95% CI: 39.1%-43.7%) were female. Pre-TEER, severe MR was present in 85.3% (95% CI: 76.1%-91.3%) of patients. Mean left ventricular ejection fraction was 36.7% (95% CI: 29.2%-44.2%), and 54.6% (95% CI: 36.9%-71.2%) of patients received mechanical circulatory support. The severity of MR post-TEER was less than 2+ in 88% (95% CI: 87%-89%) of patients. In-hospital mortality was 11% (95% CI: 10%-13%), whereas 30-day and 1-year mortality rates were 15% (95% CI: 13%-16%), and 36% (95% CI: 21%-54%), respectively. CONCLUSIONS: This systematic review and meta-analysis assessed the clinical characteristics and outcomes of TEER in CS patients with MR. TEER for MR in patients with CS has been successful in reducing MR in most of the patients, but with a high mortality rate. Randomized controlled trials of TEER for MR and CS are needed.

ABSTRACT

BACKGROUND: This network meta-analysis compares outcomes of optimal medical therapy (OMT) and pre-emptive thoracic endovascular aortic repair (TEVAR) for uncomplicated type B aortic dissection at different phases of chronicity. METHODS: MEDLINE and EMBASE were searched through November 2023. Pooled short-term outcomes (short-term mortality, perioperative complications) and long-term outcomes (all-cause mortality, aortic-related mortality, aortic re-intervention rates) were calculated. RESULTS: Systematic review identified 17 studies (2 randomized controlled trials, 3 propensity score matching, and 2 inverse probability weighting). Subacute-phase intervention had lower short-term mortality than the acute-phase (hazard ratio [HR] [95% confidence interval [CI]]=0.60 [0.38-0.94], p=0.027). No significant differences were observed in aortic rupture and paraplegia. Acute-phase TEVAR had a higher stroke incidence than subacute-phase intervention (HR [95% CI]=2.63 [1.36-5.09], p=0.042), chronic (HR [95% CI]=2.5 [1.03-6.2], p=0.043), and OMT (HR [95% CI]=1.57 [1.12-2.18], p=0.008). Acute-phase TEVAR had higher long-term all-cause mortality than subacute-phase intervention (HR [95% CI]=1.34 [1.03-1.74], p=0.03). Optimal medical therapy had elevated long-term all-cause mortality compared with subacute-phase TEVAR (HR [95% CI]=1.67 [1.25-2.33], p<0.001) and increased long-term aortic-related mortality vs acute-phase (HR [95% CI]=2.08 [1.31-3.31], p=0.002) and subacute-phase (HR [95% CI]=2.6 [1.62-4.18], p<0.01) interventions. No significant differences were observed in aortic re-intervention rates. CONCLUSIONS: Pre-emptive TEVAR may offer lower all-cause mortality and aortic-related mortality than OMT. Considering lower short-term mortality, perioperative stroke rate, and long-term mortality, our findings support pre-emptive TEVAR during the subacute phase. CLINICAL IMPACT: The optimal timing of pre-emptive thoracic endovascular aortic repair (TEVAR) for uncomplicated type B aortic dissection remains uncertain. This network meta-analysis suggests that the subacute phase (14-90 days from symptom onset) emerges as the optimal timing for pre-emptive TEVAR. This window is associated with lower rates of short-term complications and higher long-term survival rates compared with alternative strategies.

ABSTRACT

OBJECTIVE: Percutaneous deep venous arterialisation (pDVA) is a state of the art technique for treating patients with chronic limb threatening ischaemia (CLTI) with no conventional option for revascularisation. There are limited large scale data examining the clinical effectiveness of pDVA for patients with end stage CLTI. DATA SOURCES: MEDLINE, Embase, Google Scholar, and Cochrane databases. REVIEW METHODS: Four databases were searched from January 2018 to June 2024 to identify studies investigating the feasibility and clinical outcomes of pDVA for patients with CLTI with no conventional revascularisation options. Meta-analysis of time to event outcomes (mean ± standard deviation) was performed for amputation free survival as the primary outcome, and freedom from amputation and overall survival as secondary outcomes. Other secondary outcomes (mean and 95% confidence interval [CI]) were procedural success rate, patency, re-intervention, and complete wound healing. RESULTS: Ten non-randomised studies were included with 351 patients. Mean patient age was 70.3 years, and 67.6% were male. Most procedures utilised the posterior tibial artery. The aggregated rate of amputation free survival at six and 12 months (five studies, 260 patients) was 72.6 ± 2.8% and 66.0 ± 3.1%, respectively, while the overall survival at six and 12 months (five studies, 260 patients) was 85.0 ± 2.3% and 77.7 ± 2.9%, respectively. The procedural success rate (nine studies, 330 patients) was 95.5% (95% CI 92.4 - 98.7%). Primary and secondary patency at six months (four studies, 241 patients) was 23.4% (95% CI 13.6 - 33.2%) and 54.9% (95% CI 34.3 - 75.5%), respectively. The rates of re-intervention (four studies, 190 patients) and complete wound healing (seven studies, 266 patients) at six and 12 months were 15.5% (95% CI 1.4 - 29.6%) and 41.7% (95% CI 25.7 - 57.7%), respectively, for re-intervention, and 19.3% (95% CI 9.6 - 29.0%) and 46.0% (95% CI 31.7 - 60.3%) for wound healing. CONCLUSION: This meta-analysis demonstrated acceptable feasibility for no-option CLTI at highly specialised institutions for patients undergoing pDVA. Meta-analysis of time to event outcomes revealed that pDVA provides reasonable amputation free survival for up to 12 months, albeit with a overall low certainty of evidence. Wider adoption of pDVA may be considered in selective patients with CLTI, although its clinical impact and cost effectiveness require further evaluation.

ABSTRACT

BACKGROUND: The objective of the present study is to clarify safety and efficacy of thoracic endovascular aortic repair (TEVAR), excluding the primary entry in the descending aorta, for type-B0,D acute aortic dissection (TB0,DAAD) (so-called retrograde type-A acute aortic dissection). METHODS: Forty-six patients with hyperacute-phase (within 2 days after the onset) type-A acute aortic dissection (TAAAD) and TB0,DAAD underwent urgent (on the admission or next day) intervention (TEVAR or conventional surgical aortic repair [CSAR]) for 2 years. Results of TEVAR for TB0,DAAD were compared with those of CSAR for TAAAD. Outcomes included 30-day mortality, aortic reintervention, and major complications (stroke and paraplegia/paraparesis). Details of TEVAR were also analyzed. RESULTS: Seven patients with TB0,DAAD and 39 patients with TAAAD underwent respectively urgent TEVAR and CSAR. Aortic reintervention was significantly more frequent in the TEVAR than CSAR group (28.6% vs. 0%, P < 0.01). There was no difference in incidence of death and stroke between the TEVAR and CSAR group. All the 7 patients survived and 5 of the 7 (71.4%) patients were relieved of aortic reintervention for 30 days following TEVAR. One patient, however, underwent aortic arch replacement on postoperative day (POD) 1 owing to the patent and nonshrinking ascending false lumen (FL). The entry existed in the aortic arch. Another patient underwent ascending and transverse aortic replacement with frozen elephant trunk on POD13 due to proximal stent graft-induced new entry irrespective of the thrombosed and shrinking ascending FL. Because of the patent and nonshrinking ascending FL, 1 patient underwent additional TEVAR for the residual entry in the distal descending thoracic aorta on POD33 and subsequently ascending aortic replacement 4 months later. No entry was detected in the ascending or transverse aorta. The ascending FL in the other 4 patients was thrombosed early, shrinking gradually, and disappeared at last following TEVAR. CONCLUSIONS: Urgent TEVAR for TB0,DAAD may be alternative to CSAR in selected cases. Accurate diagnosis of the primary entry location on preinterventional computed tomography scans for exclusion of the entry and cautious selection and delivery of a stent graft to prevent stent graft-induced new entry or endoleak are requisite for success of the procedure, remodeling of the FL, and satisfactory prognosis.

ABSTRACT

BACKGROUND: This meta-analysis compared the outcomes of bilateral cerebral perfusion (BCP) and unilateral cerebral perfusion (UCP) in aortic surgery for acute type A aortic dissection. METHODS: A systematic literature search identified 12 studies involving 4,547 patients. Pooled odds ratios (OR) with 95% confidence intervals (CI) were calculated to analyze perioperative characteristics, short-term mortality rates, and postoperative neurological complications. RESULTS: No significant differences were found between the BCP and UCP groups in terms of cardiopulmonary bypass time, aortic cross clamp time, lowest body temperature, and lower body circulatory arrest time. Short-term mortality rates (OR [95% CI] = 0.87 [0.64-1.19], p = 0.40) and permanent neurological deficits (OR [95% CI] = 1.01 [0.69-1.47], p = 0.96) were comparable between the groups. However, subgroup analysis of studies exclusively involving total arch replacement showed a lower short-term mortality rate (OR [95% CI] = 0.42 [0.28-0.63], p < 0.01) and permanent neurological deficits (OR [95% CI] = 0.53 [0.30-0.92], p = 0.03) in the BCP group. The BCP group also had a lower rate of temporary neurological deficits (OR [95% CI] = 0.70 [0.53-0.93], p = 0.01), particularly in studies exclusively involving total arch replacement (OR [95% CI] = 0.58 [0.40-0.85], p < 0.01). CONCLUSION: This meta-analysis suggests that BCP and UCP yield comparable outcomes. However, BCP may be associated with lower short-term mortality rates and reduced incidence of neurological complications, particularly in cases requiring total arch replacement. BCP should be considered as a preferred cerebral perfusion in specific patient populations.

ABSTRACT

BACKGROUND: This meta-analysis compared survival outcomes among patients experiencing improvement in untreated significant tricuspid regurgitation (TR) following transcatheter aortic valve replacement (TAVR) for severe aortic stenosis, in contrast to those without improvement. METHODS: MEDLINE and EMBASE were searched through January 2024. Pooled hazard ratios (HR) with 95% confidence intervals (CI) were computed. Employing network meta-analysis, a comparison involving four post-procedural TR categories (improved, no improvement, worsened, and no change) was executed. Subsequently, these categories were amalgamated into two groups (less TR after TAVR and same or greater TR after TAVR), and a standard meta-analysis was conducted. Kaplan-Meier curves depicting long-term all-cause mortality were reconstructed utilizing individual patient data derived from the studies. RESULTS: A systematic review identified seven non-randomized studies encapsulating 698 patients. Network meta-analysis revealed that improved TR after TAVR correlated with significantly lower long-term all-cause mortality compared to the remaining cohorts. Similarly, pooled all-cause mortality of standard meta-analysis demonstrated significant reduction in patients whose TR was sub-baseline than those exhibiting same or greater TR after TAVR (HR [95% CI] = 0.43 [0.32-0.58], p < .01). The hazard ratio, derived from reconstructed time-to-event data, showed a lower long-term all-cause mortality in patients with less TR after TAVR relative to the other cohort (HR [95% CI] = 0.46 [0.32-0.67], p < .01). CONCLUSION: This meta-analysis revealed that improved TR after TAVR correlates with superior long-term survival. The benefits of simultaneous or staged intervention on the tricuspid valve in individuals undergoing TAVR warrant validation in future investigations.

ABSTRACT

BACKGROUND: Acute type A aortic dissection necessitates rapid and effective arterial cannulation techniques for optimal outcomes. This meta-analysis compares the safety and effectiveness of direct aortic cannulation (AoC) with peripheral cannulation (PC) via the femoral or axillary arteries in aortic surgery for acute type A aortic dissection. METHODS: A systematic review following PRISMA guidelines identified 10 retrospective studies encompassing 2518 patients (961 AoC, 1557 PC). Pooled odds ratios (OR) with 95% confidence intervals (CI) were calculated to analyze perioperative characteristics, short-term mortality rates, and postoperative complications including stroke and acute kidney injury. RESULTS: Short-term mortality did not significantly differ between AoC and PC (OR [95% CI] = 0.78 [0.61-1.01], p = .06). Likewise, postoperative stroke (OR [95% CI] = 0.86 [0.63-1.17], p = .33) nor acute kidney injury (OR [95% CI] = 1.11 [0.89-1.37], p = .35) showed no significant differences. AoC exhibited shorter operation time whereas there were no significant differences in aortic cross clamp time and cardiopulmonary bypass time between both groups. Our meta-regression analysis, considering the distal extent of aortic replacement, indicated that variations in aortic replacement rates did not significantly impact the observed outcomes. CONCLUSION: AoC is a viable alternative to PC for acute type A aortic dissection. While both approaches offer comparable outcomes, AoC's advantage in shorter operation time warrants thoughtful consideration in clinical practice.

ABSTRACT

We experienced an extremely rare case of blunt traumatic aortic arch pseudoaneurysm( BTAAPA) and report it with literature review. A 40-year-old asymptomatic man with chest X-ray abnormality visited our hospital. Contrast-enhanced computed tomography( CT) scans revealed saccular aortic-isthmus aneurysm, and BTAAPA was diagnosed because of a history of multiple severe traffic trauma 21 years before. The patient underwent replacement of the distal aortic arch and proximal descending aorta under partial cardiopulmonary bypass through left posterolateral thoracotomy. The postoperative course was uneventful. BTAAPA is exceedingly uncommon, and our comprehensive literature search identified only 9 cases including the present case. The age at diagnosis was 10 to 76 years, 7 cases were males, and most of the traumas were due to traffic accidents. The present case had the longest duration (21 years) from the trauma to the diagnosis. Six patients underwent thoracic endovascular aortic repair with good prognosis.

ABSTRACT

OBJECTIVE: The aim was to analyze the risk of progression to chronic limb-threatening ischemia (CLTI), amputation and subsequent interventions after revascularization versus noninvasive therapy in patients with intermittent claudication (IC). BACKGROUND: Conflicting evidence exists regarding adverse limb outcomes after each treatment strategy. METHODS: Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. MEDLINE, Web of Science, and Google Scholar were searched aided by a health sciences librarian through August 16, 2022. Randomized control trials (RCTs) comparing invasive (endovascular or surgical revascularization) and noninvasive treatment (exercise and/or medical treatment) were included. PROSPERO registration was completed (CRD42022352831). RESULTS: A total of 9 RCTs comprising 1477 patients (invasive, 765 patients; noninvasive, 712 patients) were eligible. During a mean of 3.6-year follow-up, progression to CLTI after invasive [5 (2-8) per 1000 person-years] and noninvasive treatment [6 (3-10) per 1000 person-years] were not statistically different [rate ratio (RR): 0.77; 95% CI, 0.35-1.69; P =0.51, I2 =0%]. Incidence of amputation (RR: 1.69; 95% CI, 0.54-5.26; P =0.36, I2 =0%) and all-cause mortality (hazard ratio: 1.26; 95% CI, 0.91-1.74; P =0.16, I2 =0%) also did not differ between the groups. However, the invasive treatment group underwent significantly more revascularizations (RR: 4.15; 95% CI, 2.80-6.16; P <0.00001, I2 =83%). The results were not changed by fixed effect or random-effects models, nor by sensitivity analysis. CONCLUSIONS: Although there is equivalent risk of progression to CLTI, major amputation and all-cause mortality compared with noninvasive treatment, invasive treatment for patients with IC led to significantly more revascularization procedures and should be used selectively in patients with major lifestyle limitation. Guideline recommendation of noninvasive treatment for first-line IC therapy is supported.

ABSTRACT

BACKGROUND: Targeted temperature management (TTM) has been recommended after cardiac arrest (CA), however the specific temperature targets and cooling methods (intravascular cooling (IVC) versus surface cooling (SC)) remain uncertain. METHODS: PUBMED and EMBASE were searched until October 8, 2022 for randomized clinical trials (RCTs) investigating the efficacy of TTM after CA. The randomized treatment arms were categorized into the following 6 groups: 31..C to 33..C IVC, 31..C to 33..C SC, 34..C to 36..C IVC, 34..C to 36..C SC, strict normothermia or fever prevention (Strict NT or FP), and standard of care without TTM (No-TTM). The primary outcome was neurological recovery. P-score was used to rank the treatments, where a larger value indicates better performance. RESULTS: We identified 15 RCTs, involving 5,218 patients with CA. Compared to No-TTM as the reference, the other therapeutic options significantly improved neurological outcomes (vs No-TTM; 31..C to 33.. C IVC: RR = 0.67, 95% CI 0.54 to 0.83; 31..C to 33..C SC RR = 0.73, 95% CI 0.61 to 0.87; 34..C to 36.. C IVC: RR = 0.66, 95% CI 0.51 to 0.86; 34..C to 36..C SC: RR = 0.73, 0.59 to 0.90; Strict NT or FP: RR = 0.75, 95% CI 0.62 to 0.90). Overall, 31-33..C IVC had the highest probability to be the best therapeutic option to improve outcomes (the ranking P-score of 0.836). As a subgroup analysis, the ranking P-score showed that IVC might be a better cooling method compared to SC (IVC vs SC P-score: 0.960 vs 0.670). CONCLUSIONS: Hypothermia (31..C to 36..C IVC and SC) and active normothermia (Strict-NT and Strict-FP) were associated with better neurological outcomes compared to No-TTM, with IVC having a greater probability of being the better cooling method than SC.

ABSTRACT

Conventional echocardiographic assessment may overestimate the left ventricular (LV) function in mitral regurgitation (MR). LV global longitudinal strain (GLS) is more sensitive marker to detect subclinical LV dysfunction. Multiple studies have investigated the prognostic value of LV-GLS in MR to examine its potential to determine the timing and indication of intervention. This systematic review aimed to assess the prognostic value of LV-GLS in patients with mitral regurgitation (MR) to define its clinical applicability. PUBMED and EMBASE were queried through July 2021 to identify studies investigating the prognostic value of LV-GLS in MR. A total of 24 observational studies with 5267 patients were identified. Sixteen studies investigated for primary MR, 7 studies for secondary MR, and 1 study for both. Most studies included patients who underwent intervention. There was significant heterogeneity in patient population, intervention status, follow-up period, LV-GLS cutoff value, outcomes, and statistical methods among the studies. Meta-analysis was not performed considering the significant variability. With exception to 1 study, all studies demonstrated significant association between impaired LV-GLS and worse clinical and echocardiographic outcomes in primary MR. Prognostic value of LV-GLS in secondary MR was less certain due to inconsistent findings and limited reporting. LV-GLS is a promising parameter of prognostication in primary MR and can be considered as alternative to determine the timing of intervention. However, the optimal cutoff value remains unclear. The prognostic value of LV-GLS in secondary MR is less clear. Further large-scale prospective study is warranted before its routine clinical application.

ABSTRACT

OBJECTIVE: Stroke is one of the devastating complications after coronary artery bypass graft (CABG). Underlying carotid artery atherosclerotic disease is reported to be an independent risk factor. The optimal treatment strategy for these patients remains under debate. METHODS: We aimed to perform a network meta-analysis to evaluate the safety and efficacy of additional carotid interventions for patients with concomitant carotid artery atherosclerotic disease who require CABG by comparing perioperative adverse event rates. All articles through February 2022 were searched using MEDLINE and EMBASE to identify studies that investigated outcomes of CABG only as well as additional staged vs combined carotid interventions by both carotid endarterectomy (CEA) and carotid artery stenting (CAS). RESULTS: Two randomized controlled trials and 23 observational studies were included, yielding a total of 32,473 patients who underwent combined CEA and CABG (n = 20,204), CEA and staged CABG (n = 6882), CABG and staged CEA (n = 340), CAS and CABG regardless of timing and sequences (n = 1224), and CABG only (n = 3823). No strategy showed a significant advantage over CABG only in all perioperative outcomes. CEA and staged CABG was associated with the lowest perioperative stroke/transient ischemic attack (TIA) rate, significantly lower compared with CAS and CABG (odds ratio [OR], 0.52; 95% confidence interval [CI], 0.36-0.76) as well as CABG and staged CEA (OR, 0.41; 95% CI, 0.23-0.74), but was also associated with the highest perioperative mortality (OR, 2.50; 95% CI, 1.67-3.85, vs CAS and CABG) and myocardial infarction rate (OR, 3.70 [95% CI, 1.16-12.5] and OR, 2.50 [95% CI, 1.35-4.55] vs CAS and CABG, vs combined CEA and CABG, respectively). CONCLUSIONS: CEA and staged CABG are associated with low perioperative stroke/transient ischemic attack rates with a tradeoff of higher mortality and myocardial infarction rate. No strategy showed a significant advantage over the CABG-only strategy in all perioperative outcomes, outlining the importance of a tailored approach and determining proper indications for carotid intervention in these patients.

ABSTRACT

BACKGROUND: Transcatheter edge-to-edge repair (TEER) may have potential benefits in the treatment of atrial functional mitral regurgitation (AFMR), but robust evidence is currently lacking. We conducted a systematic review and meta-analysis to investigate the clinical outcomes of TEER for AFMR, including comparisons to ventricular functional MR (VFMR). METHODS: MEDLINE and EMBASE were searched through January 2023 to identify studies eligible for analysis. The primary outcome was postprocedural MR severity. Postprocedural New York Heart Association (NYHA) functional class classification and all-cause mortality were also evaluated. Outcomes were stratified into short term (postprocedure to 6 months) and long term (6 months to 2 years). RESULTS: A total of eight observational studies met the inclusion criteria, enrolling 539 AFMR and 3486 VFMR patients. Postprocedural MR grade ≤2 in the AFMR group was observed in 93.7% (454/491 patients; 95% confidence interval (CI), 91.1%-96.2%, I2 = 24.3%) and 97.1% (89/93 patients; 95% CI, 92.9%-100%, I2 = 26.4%) in short- and long-term follow-up, respectively. There was no difference in the rates of postprocedural MR grade ≤2 between AFMR and VFMR either in short-term (risk ratio [RR], 1.00 [95% CI, 0.95-1.06]; p = 0.90; I2 = 53%) or long-term follow-up (RR, 1.08 [95% CI, 0.89-1.32]; p = 0.44; I2 = 22%). Similarly, no difference was observed between AFMR and VFMR in the rates of postprocedural NYHA class ≤2 or all-cause mortality. CONCLUSION: TEER provides similar clinical outcomes for AFMR and VFMR. A high rate of MR grade ≤2 was observed in patients at both short- and long-term follow-ups. Further prospective studies with TEER versus medical therapy and/or rhythm control for AFMR are warranted.

ABSTRACT

BACKGROUND: Contemporary dual antiplatelet therapy (DAPT) strategies, such as short-term DAPT or de-escalation of DAPT, have emerged as attractive strategies to treat patients with acute coronary syndrome (ACS). However, it remains uncertain whether they are suitable for elderly patients. METHODS: PubMed, Embase, and Cochrane CENTRAL databases were searched in September 2022. Randomized controlled trials (RCTs) investigating DAPT strategies, including standard (12 months), short-term, uniform de-escalation, and guided-selection strategies for elderly patients with ACS (age ≥ 65 years) were identified, and a network meta-analysis was conducted. The primary endpoint was the net clinical benefit outcome, a composite of major adverse cardiovascular events (MACEs: cardiovascular death, myocardial infarction, or stroke) and clinically relevant bleeding (equivalent to bleeding of at least type 2 according to the Bleeding Academic Research Consortium). The secondary outcomes were MACE and major bleeding. RESULTS: Sixteen RCTs with a combined total of 47,911 patients were included. The uniform de-escalation strategy was associated with an improved net clinical benefit compared with DAPT using potent P2Y12 inhibitors. The short-term DAPT strategy was associated with reduced risks of the primary outcome and major bleeding compared with DAPT using potent P2Y12 inhibitors, however, it was ranked as the least effective strategy for MACE compared with other DAPT strategies. CONCLUSIONS: Uniform de-escalation and short-term DAPT strategies may be advantageous for elderly patients, but need to be tailored based on individual bleeding and ischemic risks. Further RCTs of contemporary DAPT strategies specifically designed for elderly patients are warranted to confirm the findings of the present study.

ABSTRACT

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is as an alternative treatment to surgical AVR, but the long-term outcomes of TAVR remain unclear. AIMS: This study aimed to analyze long-term outcomes following TAVR using meta-analysis. METHODS: A literature search was performed with MEDLINE, EMBASE, Cochrane Library, Web of Science, and Google Scholar through November 2022; studies reporting clinical outcomes of TAVR with follow-up periods of ≥8 years were included. The outcomes of interest were overall survival and/or freedom from structural valve deterioration (SVD). Surgical risk was assessed with the Society of Thoracic Surgeons (STS) predicted risk of mortality (PROM) score. A subgroup analysis was conducted for intermediate-/high-surgical risk patients only. RESULTS: Eleven studies including 5458 patients were identified and analyzed. The mean age was 82.0 ± 6.5 years, and mean STS PROM score ranged from 2.9 to 10.6%. Survival rate at 5 and 10 years was 47.7% ± 1.4% and 12.1 ± 2.0%. Five studies including 1509 patients were analyzed for SVD. Freedom from SVD at 5 and 8 years was 95.5 ± 0.7% and 85.1 ± 3.1%. Similar results for survival and SVD were noted in the subgroup analysis of intermediate-/high-risk patients. CONCLUSIONS: Following TAVR, approximately 88% of patients died within 10 years, whereas 85% were free from SVD at 8 years. These date suggest that baseline patient demographic have the greatest impact on survival, and SVD does not seem to have a prognostic impact in this population. Further investigations on longer-term outcomes of younger and lower-risk patients are warranted.

ABSTRACT

Introduction: Pulmonary endarterectomy (PEA) is known to be a curative intervention for chronic thromboembolic pulmonary hypertension (CTEPH). Its complications include endobronchial bleeding, persistent pulmonary arterial hypertension, right ventricular failure, and reperfusion lung injury. Extracorporeal membranous oxygenation (ECMO) is a perioperative salvage method for PEA. Although risk factors and outcomes have been reported in several studies, overall trends remain unknown. We performed a systematic review and study-level meta-analysis to understand the outcomes of ECMO utilization in the perioperative period of PEA. Methods: We performed a literature search with PubMed and EMBASE on 11/18/2022. We included studies including patients who underwent perioperative ECMO in PEA. We collected data including baseline demographics, hemodynamic measurements, and outcomes such as mortality and weaning of ECMO and performed a study-level meta-analysis. Results: Eleven studies with 2632 patients were included in our review. ECMO insertion rate was 8.7% (225/2,625, 95% CI 5.9-12.5) in total, VV-ECMO was performed as the initial intervention in 1.1% (41/2,625, 95% CI 0.4-1.7) (Figure 3), and VA-ECMO was performed as an initial intervention in 7.1% (184/2,625, 95% CI 4.7-9.9). Preoperative hemodynamic measurements showed higher pulmonary vascular resistance, mean pulmonary arterial pressure, and lower cardiac output in the ECMO group. Mortality rates were 2.8% (32/1238, 95% CI: 1.7-4.5) in the non-ECMO group and 43.5% (115/225, 95% CI: 30.8-56.2) in the ECMO group. The proportion of patients with successful weaning of ECMO was 72.6% (111/188, 95% CI: 53.4-91.7). Regarding complications of ECMO, the incidence of bleeding and multi-organ failure were 12.2% (16/79, 95% CI: 13.0-34.8) and 16.5% (15/99, 95% CI: 9.1-28.1), respectively. Conclusion: Our systematic review showed a higher baseline cardiopulmonary risk in patients with perioperative ECMO in PEA, and its insertion rate was 8.7%. Further studies that compare the use of ECMO in high-risk patients who undergo PEA are anticipated.

ABSTRACT

OBJECTIVES: The indication, complications, and outcomes of extracorporeal membrane oxygenation (ECMO) in children with COVID-19-related illnesses remain unelucidated. Our study aimed to investigate the characteristics and outcomes of ECMO in children with COVID-19-related illnesses. DATA SOURCES: We searched PubMed and EMBASE databases in March 2022. STUDY SELECTION: We retrieved all studies involving children (age ≤ 18 yr) with COVID-19-related illnesses who received ECMO. DATA EXTRACTION: Two authors independently extracted data and assessed the risk of bias. Mortality, successful weaning rate, and complications while on ECMO were synthesized by a one-group meta-analysis using a random-effect model. Meta-regression was performed to explore the risk factors for mortality. DATA SYNTHESIS: We included 18 observational studies, four case series, and 22 case reports involving 110 children with COVID-19-related illnesses receiving ECMO. The median age was 8 years (range, 10 d to 18 yr), and the median body mass index was 21.4 kg/m 2 (range, 12.3-56.0 kg/m 2 ). The most common comorbidities were obesity (11% [7/63]) and congenital heart disease (11% [7/63]), whereas 48% (30/63) were previously healthy. The most common indications for ECMO were multisystem inflammatory syndrome in children (52% [47/90]) and severe acute respiratory distress syndrome (40% [36/90]). Seventy-one percent (56/79) received venoarterial-ECMO. The median ECMO runtime was 6 days (range, 3-51 d) for venoarterial ECMO and 11 days (range, 3-71 d) for venovenous ECMO. The mortality was 26.6% (95% CI, 15.9-40.9), and the successful weaning rate was 77.0% (95% CI, 55.4-90.1). Complications were seen in 37.0% (95% CI, 23.1-53.5) while on ECMO, including stroke, acute kidney injury, pulmonary edema, and thromboembolism. Corticosteroids and IV immunoglobulin therapies were associated with lower mortality. CONCLUSIONS: The mortality of children on ECMO for COVID-19 was relatively low. This invasive treatment can be considered as a treatment option for critically ill children with COVID-19.

ABSTRACT

There is a paucity of longitudinal data on cardiac outcomes in multisystem inflammatory syndrome in children (MIS-C) associated with COVID-19. We aimed to investigate the longitudinal cardiovascular outcomes in MIS-C. PubMed and EMBASE were searched through May 2022. Observational studies were included, reporting mid-term (≥ 3 months) outcomes in children (aged < 21) with MIS-C. Data were extracted by two researchers. Longitudinal outcomes were synthesized by a one-group meta-analysis using a random-effects model. Eleven studies with a follow-up period (3 months to 1 year) were identified, including 547 MIS-C patients. The mortality was 2.5% (95% CI 1.3-4.9). The majority of left ventricular (LV) systolic dysfunction present in 46.8% (95% CI 32.7-61.3) in the acute phase resolved by 3 months, and the prevalence of LV systolic dysfunction was 1.7% (95% CI 0.5-5.7) and 2.1% (95% CI 0.8-5.4) at 3 month and 6 month follow-up, respectively. Additionally, the persistent LV systolic dysfunction in the small population was mild. However, coronary abnormalities such as coronary artery dilatation or aneurysms, seen in 23.7% (95% CI 17.7-31.1) at baseline, persisted in 4.7% (95% CI 1.5-14.3) at 3 months and 5.2% (95% CI 3.0-8.9) at 6 months. Mitral regurgitation (MR), which was observed in 56.6% (95% CI 27.7-81.6) at baseline, also persisted in 7.5% at 6 months. In conclusion, our study demonstrated largely favorable cardiac outcomes, suggesting resolution of LV systolic dysfunction in the majority of cases. However, coronary abnormalities and MR persisted in a subset of patients at mid-term follow-up.

ABSTRACT

The optimal treatment strategy using pulmonary vasodilators in pulmonary arterial hypertension associated with CHD (PAH-CHD) remains controversial. We aimed to compare the efficacy and safety of pulmonary vasodilators in PAH-CHD. PubMed and EMBASE databases were searched through May 2022 and a network meta-analysis was conducted. The primary outcomes were mean difference of changes in 6-minute walk distance, NYHA functional class, and N-terminal pro-brain natriuretic peptide. The secondary outcomes included pulmonary vascular resistance, mean pulmonary arterial pressure, and resting oxygen saturation. We identified 14 studies, yielding 807 patients with PAH-CHD. Bosentan and sildenafil were associated with a significant increase in 6-minute walk distance from baseline compared with placebo (MD 48.92 m, 95% CI 0.32 to 97.55 and MD 59.70 m, 95% CI 0.88 to 118.53, respectively). Bosentan, sildenafil, and combination of bosentan and sildenafil were associated with significant improvement in NYHA functional class compared with placebo (MD -0.33, 95% CI -0.51 to -0.14, MD -0.58, 95% CI -0.75 to -0.22 and MD -0.62, 95% CI -0.92 to -0.31, respectively). Bosentan and sildenafil were also associated with significant improvements in secondary outcomes. These findings were largely confirmed in the subgroup analysis. Various adverse events were reported; however, serious adverse event rates were relatively low (4.8-8.7%), including right heart failure, acute kidney injury, respiratory failure, hypotension, and discontinuation of pulmonary vasodilators. In conclusion, bosentan and sildenafil were the most effective in improving prognostic risk factor such as 6-minute walk distance and NYHA class. Overall, pulmonary vasodilators were well tolerated in PAH-CHD.
