ABSTRACT
Radial artery occlusion (RAO) is a major impediment to reintervention in patients who underwent proximal transradial access (p-TRA) for coronary catheterization. Distal transradial access (d-TRA) at the level of snuffbox distal to the radial artery bifurcation is a novel alternative to p-TRA. We conducted an updated meta-analysis of all available randomized controlled trials (RCTs) to compare the incidence of RAO between p-TRA and d-TRA, along with access site-related complications. PubMed, Web of Science, and Google Scholar were searched for RCTs published since 2017 to October 2023 comparing d-TRA and p-TRA for coronary angiography and/or intervention. Risk ratios (RRs) and mean differences (MDs) with 95% confidence intervals were calculated using the random-effects model for procedural and clinical outcomes for the 2 approaches. A total of 18 RCTs with 8,205 patients (d-TRA n = 4,096, p-TRA n = 4,109) were included. The risk of RAO (RR 0.31, 0.21 to 0.46, p ≤0.001) and time to hemostasis (minutes) (MD -51.18, -70.62 to -31.73, p <0.001) was significantly lower in the d-TRA group. Crossover rates (RR 2.39, 1.71 to 3.32, p <0.001), access time (minutes) (MD 0.93, 0.50 to 1.37, p <0.001), procedural pain (MD 0.46, 0.13 to 0.79, p = 0.006), and multiple puncture attempts (RR 2.13, 1.10 to 4.11, p = 0.03) were significantly higher in the d-TRA group. The use of d-TRA for coronary angiography and/or intervention is associated with a lower risk of RAO at the forearm and may preserve p-TRA site for reintervention in selective patients by reducing the incidence of RAO.

Timely revascularization is essential for limb salvage and to reduce mortality in patients with chronic limb-threatening ischemia (CLTI). In patients who are candidates for endovascular therapy and surgical bypass, the optimal revascularization strategy remains uncertain. Recently published randomized controlled trials (RCTs) have presented conflicting results. We conducted a trial-level meta-analysis to compare the outcomes between endovascular-first and surgery-first strategies for revascularization. PubMed, Web of Science, and the Cochrane Library were searched to identify RCTs comparing the outcomes of endovascular-first versus surgery-first strategies for revascularization in patients with CLTI. Data were pooled for major outcomes and their aggregate risk ratios (RRs) with 95% confidence intervals were calculated using a random-effects model. Kaplan-Meier curves for amputation-free survival and overall survival time were plotted using the pooled aggregated data from published curves, with their corresponding hazard ratios (HRs) and 95% confidence intervals reported for up to 5 years of follow-up. A total of 3 RCTs with 2,627 patients (1,312 endovascular-first and 1,315 surgery-first) were included in the meta-analysis. Of these, 1,864 patients (70.9%) were men and 347 (13.2%) were older than 80 years. Comparing the endovascular-first and surgery-first approaches, there was no significant difference in the overall (HR 0.92 [0.83 to 1.01], p = 0.09) or amputation-free survival (HR 0.98 [0.92 to 1.03], p = 0.42), reintervention (RR 1.24 [0.74 to 2.07], p = 0.41), major amputation, (RR 1.16 [0.87 to 1.54], p = 0.31), or therapeutic crossover (RR 0.92 [0.37 to 2.26], p = 0.85). In conclusion, data from available RCTs suggest that there is no difference in clinical outcomes between endovascular-first and surgery-first revascularization strategies for CLTI. A planned patient-level meta-analysis may provide further insight.

Patients who underwent transcatheter aortic valve implantation (TAVI) with concomitant atrial fibrillation (AF) are at a higher risk for thromboembolic and bleeding events. The optimal antithrombotic strategy for patients with AF after TAVI remains unclear. We sought to determine the comparative efficacy and safety of direct oral anticoagulants (DOAC) versus oral vitamin K antagonists (VKAs) in these patients. Electronic databases such as PubMed, Cochrane, and Embase databases were searched till January 31, 2023, for relevant studies evaluating clinical outcomes of VKA versus DOAC in patients with AF after TAVI. Outcomes assessed were (1) all-cause mortality, (2) stroke, (3) major/life-threatening bleeding, and (4) any bleeding. Hazard ratios (HRs) were pooled in meta-analysis using random effect model. Nine studies (2 randomized and 7 observational) were included in systematic review, and 8 studies with 25,769 patients were eligible to be included in the meta-analysis. The mean age of the patients was 82.1 years, and 48.3% were male. Pooled analysis using random-effects model showed no statistically significant difference in all-cause mortality (HR 0.91, 95% confidence interval [CI] 0.76 to 1.10, p = 0.33), stroke (HR 0.96, 95% CI 0.80 to 1.16, p = 0.70), and major/life-threatening bleeding (HR 1.05, 95% CI 0.82 to 1.35, p = 0.70) in patients that received DOAC compared with oral VKA. Risk of any bleeding was lower in the DOAC group compared with oral VKA (HR 0.83, 95% CI 0.76 to 0.91, p = 0.0001). In patients with AF, DOACs appear to be a safe alternative oral anticoagulation strategy to oral VKA after TAVI. Further randomized studies are required to confirm the role of DOACs in those patients.

BACKGROUND: Outcomes following in-hospital cardiac arrest (IHCA) in patients with COVID-19 have been reported by several small single-institutional studies; however, there are no large studies contrasting COVID-19 IHCA with non-COVID-19 IHCA. The objective of this study was to compare the outcomes following IHCA between COVID-19 and non-COVID-19 patients. METHODS: We searched databases using predefined search terms and appropriate Boolean operators. All the relevant articles published till August 2022 were included in the analyses. The systematic review and meta-analysis were conducted as per Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. An odds ratio with a 95% confidence interval (CI) was used to measure effects. RESULTS: Among 855 studies screened, 6 studies with 27,453 IHCA patients (63.84% male) with COVID-19 and 20,766 (59.7% male) without COVID-19 were included in the analysis. IHCA among patients with COVID-19 has lower odds of achieving return of spontaneous circulation (ROSC) (OR: 0.66, 95% CI: 0.62-0.70). Similarly, patients with COVID-19 have higher odds of 30-day mortality following IHCA (OR: 2.26, 95% CI: 2.08-2.45) and have 45% lower odds of cardiac arrest because of a shockable rhythm (OR: 0.55, 95% CI: 0.50-0.60) (9.59% vs. 16.39%). COVID-19 patients less commonly underwent targeted temperature management (TTM) or coronary angiography; however, they were more commonly intubated and on vasopressor therapy as compared to patients who did not have a COVID-19 infection. CONCLUSIONS: This meta-analysis showed that IHCA with COVID-19 has a higher mortality and lower rates of ROSC compared with non-COVID-19 IHCA. COVID-19 is an independent risk factor for poor outcomes in IHCA patients.
ABSTRACT
BACKGROUND: In-hospital cardiac arrest during cardiac catheterization is not uncommon. The extent of variation in survival after cardiac arrest occurring in the cardiac catheterization laboratory (CCL) and underlying factors are not well known. OBJECTIVES: The aim of this study was to identify the factors associated with higher survival rates after an index cardiac arrest in the CCL. METHODS: Within the GWTG (Get With The Guidelines)-Resuscitation registry, patients ≥18 years of age who had index in-hospital cardiac arrest in the CCL between January 1, 2003, and December 31, 2017, were identified. Hierarchical models were used to adjust for demographics, comorbidities, and cardiac arrest characteristics to generate risk-adjusted survival rates (RASRs) to discharge for each hospital with ≥5 cases during the study period. Median OR was used to quantify the extent of hospital-level variation in RASR. RESULTS: The study included 4,787 patients from 231 hospitals. The median RASR was 36% (IQR: 21%) and varied from a median of 20% to 52% among hospitals in the lowest and highest tertiles of RASR, respectively. The median OR was 1.71 (95% CI: 1.52-1.87), suggesting that the odds of survival for patients with identical characteristics with in-hospital cardiac arrest in the CCL from 2 randomly chosen different hospitals varied by 71%. Hospitals with greater annual numbers of cardiac arrest cases in the CCL had higher RASRs. CONCLUSIONS: Even in controlled settings such as the CCL, there is significant hospital-level variation in survival after in-hospital cardiac arrest, which suggests an important opportunity to improve resuscitation outcomes in procedural areas.

Background: To date, only dexamethasone and tocilizumab have been shown to reduce mortality in patients with COVID-19. Baricitinib is a Janus kinase 1/2 inhibitor with known anti-inflammatory and anti-viral properties. We performed a meta-analysis of RCTs assessing the role of baricitinib in hospitalised patients with COVID-19. Methods: Electronic databases such as MEDLINE, EMBASE, and Cochrane Central were searched up until March 31, 2022, for RCTs evaluating the efficacy of baricitinib in hospitalised patients with COVID-19. The outcomes assessed were 28-day mortality, progression to invasive mechanical ventilation (IMV) or ECMO, progression to respiratory failure needing positive pressure ventilation, IMV or death, duration of hospitalisation and time to discharge. The meta-analysis was registered in the PROSPERO database (CRD42022314579). Findings: Four studies (with 10,815 patients) were included in the analysis. Pooled analysis using random-effects model showed a statistically significant reduction in 28-day mortality (OR 0.69, 95% CI 0.50-0.94; p=0.04, I2=65%) and composite outcome of progression to severe disease needing positive pressure ventilation, IMV or death (OR 0.89, 95% CI 0.80-0.99, p= 0.03, I2=0%). There was a favorable trend towards reduced progression to IMV or ECMO (OR 0.76, 95% CI 0.58-1.01; p=0.06, I2=49%) in the baricitinib arm compared to standard therapy, even though it was not statistically significant. Statistical significance was achieved for all outcomes with fixed-effects model analysis. Interpretation: In hospitalised patients with COVID-19, baricitinib was associated with reduced 28-day mortality although there was not a statistically significant reduction in progression to IMV or ECMO. Baricitinib used in conjunction with standard of care treatments is associated with improved mortality in hospitalised patients with COVID-19 disease. Funding: None.
ABSTRACT
Glutamic acid decarboxylase 65kD autoantibody (GAD65Ab) is frequently detected in patients with refractory epilepsy and stiff person syndrome. In contrast to T1D, the pathological role of GAD65Ab in neurological disorders is still debatable. As a result, the implementation of possible immunotherapy is usually delayed. This report presents 2 cases of GAD65Ab-associated brain autoimmunity and their different management. We present clinical data and discuss management based on available evidence in the reviewed literature. Both cases presented with acute on chronic neurological symptoms and were GAD65Ab positive. Case 1, a 30-year-old man with a history of early-onset type 1 diabetes mellitus at 14 months, followed by cryptogenic temporal epilepsy at 11 years of age, presented with intractable seizures. Case 2, a 48-year-old woman, presented with a history of recurrent severe headaches, cognitive impairment, decreased memory, and behavioral symptoms. GAD65Ab was detected in both patients' sera. Cerebrospinal fluid GAD65Ab was only checked and positive in case 1. Case 2 was diagnosed with limbic encephalitis, treated with immunotherapy, and showed a remarkable clinical improvement. Case 1 with refractory epilepsy failed multiple antiepileptic drugs and responsive-stimulator system treatments. He was finally diagnosed with autoimmune epilepsy. The delay in diagnosis resulted in a lost opportunity for early immunotherapy. In conclusion, autoantibody screening and early initiation of immunotherapy should be considered to manage GAD65Ab-associated neurological disorders.
ABSTRACT
BACKGROUND: Intravascular lithotripsy (IVL) is a novel tool for the treatment of calcified vascular stenosis. Recently, IVL has been successfully used for modification of calcified plaque in coronary and lower extremity peripheral arteries with promising results. However, experience in subclavian and innominate peripheral arterial disease is limited. This study aims to report our initial experience of IVL use in calcified subclavian and innominate vasculature. METHODS: This was a retrospective review of all the cases of IVL performed in subclavian and innominate arteries at the Miriam Hospital, Providence, between January 2019 and May 2020. Data on the baseline and procedural characteristics were collected. The primary endpoint was procedural success defined as residual stenosis of <20% after stenting. Other endpoints of interest were; 1) procedural complications, including dissections, perforations, abrupt closure, slow or no-reflow, thrombosis, and distal embolization; 2) in-hospital major adverse cardiac events (MACE) defined as a composite of death, myocardial infarction, or stroke/transient ischemic attack. RESULTS: A total of 7 patients with 13 lesions undergoing IVL were included. Of these, 5 (71%) were women, the mean age was 74.6 ± 12.9, and the mean BMI was 25.1 ± 6.7. IVL was successfully delivered to all the target lesions with a mean 252.9 ± 54.4 pulses delivered per patient. Procedural success was achieved in 100% of the treated lesions. No procedure-related complications or in-hospital MACE occurred in any of the patients. CONCLUSIONS: In this single-center retrospective analysis, IVL facilitated acute procedural success without any procedural complications in severely calcified stenoses of the subclavian and innominate vasculature. Larger studies with an active comparator and longer follow-up are needed to establish the relative efficacy and safety of IVL use in this vascular bed.

BACKGROUND: Acute myocardial infarction complicated by cardiogenic shock (AMICS) is associated with high mortality rates. Data has shown that intra-aortic balloon pump (IABP) support does not provide a survival benefit over optimal medical therapy in AMICS. Despite lack of supportive evidence, IABP is still commonly used in these clinical situations. The Impella percutaneous ventricular assist device (PVAD) (Abiomed, Denver, MA) rapidly deploys superior mechanical circulatory support (MCS) in patients with AMICS. However, the safety and efficacy of Impella in AMICS is a matter of ongoing investigation, and its role in AMICS management is not yet fully established. METHODS: The databases of Pubmed, EMBASE and Cochrane Central databases were searched from inception to March 2020. Relevant randomized trials and observational studies comparing Impella versus IABP in AMICS were identified and a meta-analysis was performed using the random effect model. The efficacy endpoint of interest was short-term mortality (defined as in-hospital or 30-day mortality). The safety endpoints of interest were major bleeding, limb complications, stroke and hemolysis. RESULTS: A total of 2 randomized trials and 5 observational studies with 3921 patients were included. No difference in short-term mortality between the two groups [RR 1.08, 95% CI 0.87-1.33, P = 0.49] was found. For safety endpoints, Impella was associated with significantly higher incidence of major bleeding [RR: 2.03, 95% CI 1.56-2.64, P < 0.0001], limb complications [RR: 3.67, 95% CI 1.56-8.65, P = 0.003] as well as hemolysis [RR: 9.46, 95% CI 1.75-51.22, P = 0.009] compared with IABP. No significant difference was observed for the incidence of stroke [RR: 1.07 95% CI 0.34-3.31 P = 0.91]. CONCLUSION: Impella support in AMICS patients was associated with a significantly increased risk of bleeding, limb complications and hemolysis without an improved short-term survival advantage compared with IABP.

Venous thromboembolism (VTE) is a common complication in cancer patients and is associated with increased morbidity and mortality. Lung cancer is commonly associated with VTE including pulmonary embolism. We did a retrospective analysis from the 2013 Healthcare Cost and Utilization Project data to determine the role of age as a factor in the development of VTE in this patient group. Patients were selected using the International Classification of Diseases, Ninth Revision (ICD-9) diagnosis codes for metastatic lung cancer and VTE. The patients were stratified by age, sex, race/ethnicity, and site of VTE. There was a total of 16,577 VTE events detected out of a total of 182,863 cases of metastatic lung cancer, representing 9% of the total cases. In patients under 65 years of age, there were 356.82 more cases of pulmonary embolism per 100,000 individuals compared to those older than 65 years (p<0.0001). The same age group also showed 374.83 more upper extremity VTE, 286.94 more non-pulmonary thoracic VTE, and 263.97 more abdominal VTE events per 100,000 individuals (p<0.0001). In conclusion, we found that patients under the age of 65 years had a significantly higher incidence of VTE, pulmonary embolism, upper extremity VTE as well as abdominal and non-pulmonary VTE.
ABSTRACT
Cell therapy involves transplantation of human cells to promote repair of diseased or injured tissues and/or cells. Only a limited number of mostly small-scale trials have studied cell therapy in nonischemic cardiomyopathy (NICM). We performed a meta-analysis of randomized clinical trials (RCTs) to assess the safety and efficacy of cell therapy in NICM. Electronic databases were searched for relevant RCTs from inception until August 2020. Outcomes assessed were left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter or volume (LVEDD), quality of life (QoL) indices, and major adverse cardiac events (MACEs). Weighted mean differences (MDs) and standardized mean differences (SMDs) were calculated using random-effects methods. Eleven RCTs with 574 participants were included in the analysis. There was a significant increase in mean LVEF (MD, 4.17%; 95% confidence interval [CI] = 1.66-6.69) and modest decrease in LVEDD (SMD, -0.50; 95% CI = -0.95 to -0.06) in patients treated with cell therapy compared with controls. Cell therapy was also associated with improvement in functional capacity, as assessed by the 6-minute walking distance (MD, 72.49 m; 95% CI = 3.44-141.53). No significant differences were seen in MACEs and QoL indices between treated and control groups. This meta-analysis suggests that cell therapy may improve LV systolic function and may be associated with improvement in LVEDD and functional capacity compared with maximal medical therapy. Cell therapy was safe, with no significant difference in MACEs between treatment and control groups. However, given the limitations of current studies, larger well-designed RCTs are needed to evaluate the efficacy of cell therapy in patients with NICM.

BACKGROUND: To date, only dexamethasone has been shown to reduce mortality in coronavirus disease-19 (COVID-19) patients. Tocilizumab has been recently added to the treatment guidelines for hospitalized COVID-19 patients, but data remain conflicting. STUDY DESIGN AND METHODS: Electronic databases such as MEDLINE, EMBASE, and Cochrane central were searched from March 1, 2020, until March 10, 2021, for randomized controlled trials evaluating the efficacy of tocilizumab in hospitalized COVID-19 patients. The outcomes assessed were all-cause mortality, mechanical ventilation, and time to discharge. RESULTS: Nine studies (with 6490 patients) were included in the analysis. In total, 3358 patients received tocilizumab, and 3132 received standard care/placebo. Pooled analysis showed a significantly decreased risk of all-cause mortality (RR 0.89, 95% CI 0.80-0.98, p = 0.02) and progression to mechanical ventilation (RR 0.80, 95% CI 0.71-0.89, p < 0.0001) in the tocilizumab arm compared to standard therapy or placebo. In addition, there was a trend towards improved median time to hospital discharge (RR 1.28, 95% CI 1.12-1.45, p = 0.0002). CONCLUSIONS: Tocilizumab therapy improves outcomes of mortality and need for mechanical ventilation, in hospitalized patients with COVID-19 infection compared with standard therapy or placebo. Our findings suggest the efficacy of tocilizumab therapy in hospitalized COVID-19 patients and strengthen the concept that tocilizumab is a promising therapeutic intervention to improve mortality and morbidity in COVID-19 patients.

Heart failure with preserved ejection fraction (HFpEF) accounts for almost one-half of all heart failure (HF) patients and continues to increase in prevalence. While mortality with heart failure with reduced ejection fraction (HFrEF) has decreased over the past few decades with use of evidence-based HFrEF therapy, mortality related to heart failure with HFpEF has not changed significantly over the same time period. The combination of poor prognosis and lack of effective treatment options creates a pressing need for novel strategies for better patient characterization. We conducted a systematic review to evaluate the prognostic value of cardiac magnetic resonance (CMR)-derived T1 relaxation time and extracellular volume fraction (ECV) in HFpEF patients. PubMed, Embase, and Cochrane Central were searched for relevant studies. The primary outcomes of interest were hospitalization for HF and all-cause mortality. Five studies with 2741 patients were included. Four studies reported correlation of outcomes with ECV, 2 studies reported correlation of outcomes with native T1 time, and 1 study reported correlation of outcomes with post-contrast T1 time. All five studies showed significant correlation of CMR-derived parameters with adverse outcomes including event-free survival to cardiac event, all cause, and cardiac mortality. CMR-determined ECV is strongly correlated with adverse outcomes in HFpEF cohorts.

Endovascular interventions are commonly utilized for treatment of femoropopliteal peripheral artery disease. The relative efficacy of these interventions remains unclear. A Bayesian network meta-analysis was performed comparing 5 endovascular treatment modalities: balloon angioplasty (BA), bare metal stent (BMS), covered stent (CS), drug-coated balloon (DCB), drug-eluting stent (DES) for femoropopliteal peripheral artery disease. The primary efficacy end points were freedom from target lesion revascularization (TLR) and primary patency at 12 months. BA was the reference treatment. Twenty-two trials including 4,381 participants provided data on TLR. Sixteen trials including 3,691 participants provided data on primary patency. Point estimates for DCB suggested that it was the most efficacious treatment for freedom from TLR (odds ratio [OR] 4.23; 95% credible intervals [CrI] 2.43 to 7.66) followed by CS (OR 3.65; 95% CrI 1.11 to 12.55), DES (OR 2.64; 95% CrI 0.72 to 9.77), and BMS (OR 2.3; 95% CrI 1.11 to 4.76). Similarly, point estimates for primary patency were highest with DES (OR 8.93; 95% CrI 3.04, 27.14) followed by CS (OR 3.91; 95% CrI 1.18, 13.84), DCB (OR 3.32; 95% CrI 1.8, 6.25), and BMS (OR 3.5; 95% CrI 1.58, 7.99). In conclusion, DCB has the lowest need for TLR whereas DES has the highest primary patency rate. DCB, CS, and BMS were associated with significant reductions in TLR compared with BA, whereas DCB, DES, CS, and BMS were associated with significantly improved primary patency compared with BA.

BACKGROUND: Whether revascularization should be performed as multivessel intervention at the time of index procedure (MV-index), staged procedure (MV-staged), or culprit only intervention (COI) in patients with multivessel disease (MVD) presenting with acute coronary syndrome (ACS) is unclear. We performed a systematic review and network meta-analysis of randomized controlled trials to assess the optimal revascularization strategy in this patient population. METHODS: PubMed, Embase, and Cochrane Central databases were systematically searched to identify all relevant studies. The outcomes assessed were major cardiac adverse events (MACE), all-cause mortality, cardiovascular mortality, myocardial infarction (MI), and revascularization. A Bayesian random-effects network meta-analysis was used to calculate odds ratio (OR) with credible interval (CrI). RESULTS: Thirteen studies with 8,066 patients were included in the analysis. There was a decreased risk of MACE (MV-index vs. COI: OR, 0.35; 95% CrI, 0.23-0.55; MV-staged vs COI: OR, 0.52; 95% CrI, 0.31-0.81) and revascularization (MV-index vs. COI: OR, 0.27; 95% CrI, 0.15-0.49; MV-staged vs. COI: OR, 0.38; 95% CrI, 0.19-0.70) with MV-index intervention and MV-staged intervention compared with COI. However, MV-index intervention and not MV-staged intervention was associated with a decreased risk of MI (MV-index vs. COI: OR, 0.35; 95% CrI, 0.12-0.93; MV-staged vs. COI: OR, 0.65; 95% CrI, 0.24-1.59) compared with COI. CONCLUSIONS: Our analysis suggests that multivessel intervention either at index procedure or as staged intervention may be more efficacious compared to COI in patients with MVD presenting with ACS.

BACKGROUND: Patients with atrial fibrillation undergoing percutaneous coronary intervention have indications for oral anticoagulation and dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 receptor inhibitor. The concurrent use of all three agents, termed triple oral antithrombotic therapy (TAT), increases the risk of bleeding. A number of prospective trials showed that the omission of aspirin mitigates the risk of bleeding without affecting major adverse cardiovascular event (MACE). MATERIALS AND METHODS: The databases of PubMed, Embase, and Cochrane Central databases were searched from inception to October 2019. Relevant randomized control trials comparing dual antithrombotic therapy (DAT) versus TAT were identified and a metanalysis was performed using random-effect model. The safety endpoints of interest were thrombolysis in myocardial infarction criteria (TIMI) major and minor bleeding, TIMI major bleeding, and intracranial bleeding. The efficacy endpoints of interest were MACE and individual components of MACE. RESULTS: Six trials with 11,722 patients were included. For safety endpoint, DAT was associated with significantly lower incidence of TIMI major and minor bleeding [RR: 0.58, 95% CI 0.44-0.77, P = 0.0001], TIMI major bleeding [RR: 0.55, 95% CI 0.42-0.73, P < 0.0001] as well as intracranial bleeding [RR: 0.35, 95% CI 0.16-0.73, P = 0.006] compared with TAT. No significant difference was observed for MACE [RR: 0.96 (0.79-1.17) P = 0.71] or any of the individual components of MACE between the two groups. CONCLUSION: Omission of aspirin from TAT in patients with Atrial Fibrillation (AF) after percutaneous coronary intervention is associated with lower risk of bleeding without compromising the efficacy in terms of mortality and cardiovascular thrombotic events.
ABSTRACT
Intravascular lithotripsy (IVL) is an emerging approach for modification of calcified atherosclerotic plaque. We report 2 cases of IVL used for calcific mesenteric stenosis, one in de novo superior mesenteric artery stenosis and another in celiac artery in-stent restenosis. In both cases, IVL was used successfully, reducing stenosis without any complications. (Level of Difficulty: Intermediate.).
