RESUMEN
BACKGROUND: Despite optimal medical therapy and cardiac resynchronization therapy (CRT), significant functional mitral regurgitation (MR) persisted in 30% of the patients and labeled as CRT nonresponders. AIMS: We sought to study the impact of transcatheter edge-to-edge repair (TEER) in patients with symptomatic grade III and IV functional MR despite CRT. METHODS: A retrospective analysis was conducted of all patients who had prior CRT for at least 6 months and underwent TEER for significant residual functional MR (grade ≥3) and symptomatic heart failure (HF) at our institution. The primary outcomes were the change in New York Heart Association classification (NYHA), MR grade, echo parameters, and NT-ProBNP from baseline to 1-year post-procedure. RESULTS: A total of 28 patients were identified, mean age of 73 ± 6.7 years and 89% males. Procedure success was achieved in all patients. At 1-year follow-up, patients had lower MR grade (median 2, IQR 1 [1,2] vs. 4, IQR 1 [3,4]; p < 0.001), NYHA class (median 2, IQR 1 [2,3] vs. 3, IQR 1 [3,4]; p < 0.001), and NT-ProBNP (7658 ± 11322 vs. 3760 ± 4431; p = 0.035) compared to before the TEER procedure. The left ventricular end-diastolic volume (255 ± 59 vs. 244 ± 66 mm; p = 0.016) and the right ventricular systolic pressure (52 ± 14 mmHg vs. 37 ± 13 mmHg, <0.001) decreased. CONCLUSION: Patients who remain symptomatic after CRT with severe functional MR had improved functional status and MR grade at 1-year following TEER. There was a signal toward reverse remodeling.
RESUMEN
BACKGROUND: Studies comparing plug-based (i.e., MANTA) with suture-based (i.e., ProStar XL and ProGlide) vascular closure devices (VCDs) for large-bore access closure after transcatheter aortic valve replacement (TAVR) have yielded mixed results. AIMS: To examine the comparative safety and efficacy of both types of VCDs among TAVR recipients. METHODS: An electronic database search was performed through March 2022 for studies comparing access-site related vascular complications with plug-based versus suture-based VCDs for large-bore access site closure after transfemoral (TF) TAVR. RESULTS: Ten studies (2 randomized controlled trials [RCTs] and 8 observational studies) with 3113 patients (MANTA = 1358, ProGlide/ProStar XL = 1755) were included. There was no difference between plug-based and suture-based VCD in the incidence of access-site major vascular complications (3.1% vs. 3.3%, odds ratio [OR]: 0.89; 95% confidence interval [CI]: 0.52-1.53). The incidence of VCD failure was lower in plug-based VCD (5.2% vs. 7.1%, OR: 0.64; 95% CI: 0.44-0.91). There was a trend toward a higher incidence of unplanned vascular intervention in plug-based VCD (8.2% vs. 5.9%, OR: 1.35; 95% CI: 0.97-1.89). Length of stay was shorter with MANTA. Subgroup analyses suggested significant interaction based on study designs such that there was higher incidence of access-site vascular complications and bleeding events with plug-based versus suture-based VCD among RCTs. CONCLUSION: In patients undergoing TF-TAVR, large-bore access site closure with plug-based VCD was associated with a similar safety profile as suture-based VCD. However, subgroup analysis showed that plug-based VCD was associated with higher incidence of vascular and bleeding complications in RCTs.

BACKGROUND: TandemHeart has been demonstrated to improve hemodynamic and metabolic complications in cardiogenic shock (CS). Contemporary outcomes have not been reported. OBJECTIVES: To evaluate the outcomes of the TandemHeart (LivaNova) in contemporary real-world use. METHODS: We analyzed baseline characteristics, hemodynamic changes, and outcomes of all patients treated with TandemHeart who were enrolled in the THEME registry, a multicenter, prospective, observational study. RESULTS: Between May 2015 and June 2019, 50 patients underwent implantation of the TandemHeart device. 22% of patients had TandemHeart implanted within 12 h, 32% within 24 h, and 52% within 48 h of CS diagnosis. Cardiac index (CI) was significantly improved 24 h after implantation (median change 1.0, interquartile range (IQR) (0.5-1.4 L/min/m2 ). In survivors, there was a significant improvement in CI (1.0, IQR (0.5-2.25 L/min/m2 ) and lactate clearance -2.3 (-5.0 to -0.7 mmol/L). The 30-day and 180-day survival were 74% (95% confidence interval: 60%-85%) and 66% (95% confidence interval: 51%-79%), respectively. Survival was similarly high in those in whom TandemHeart has been used as a bridge to surgery (85% 180-day survival). CONCLUSION: In a contemporary cohort of patients presenting in CS, the use of TandemHeart is associated with a 74% 30-day survival and a 66% 180-day survival.

BACKGROUND: Aortic stenosis (AS) is associated with myocardial ischemia through different mechanisms and may impair coronary arterial flow. However, data on the impact of moderate AS in patients with acute myocardial infarction (MI) is limited. AIMS: This study aimed to investigate the impact of moderate AS in patients presenting with acute myocardial infarction (MI). METHODS: We conducted a retrospective analysis of all patients who presented with acute MI to all Mayo Clinic hospitals, using the Enterprise Mayo PCI Database from 2005 to 2016. Patients were stratified into two groups: moderate AS and mild/no AS. The primary outcome was all cause mortality. RESULTS: The moderate AS group included 183 (13.3%) patients, and the mild/no AS group included 1190 (86.7%) patients. During hospitalization, there was no difference between both groups in mortality. Patients with moderate AS had higher in-hospital congestive heart failure (CHF) (8.2% vs. 4.4%, p = 0.025) compared with mild/no AS patients. At 1-year follow-up, patients with moderate AS had higher mortality (23.9% vs. 8.1%, p < 0.001) and higher CHF hospitalization (8.3% vs. 3.7%, p = 0.028). In multivariate analysis, moderate AS was associated with higher mortality at 1-year (odds ratio 2.4, 95% confidence interval [1.4-4.1], p = 0.002). In subgroup analyses, moderate AS increased all-cause mortality in STEMI and NSTEMI patients. CONCLUSION: The presence of moderate AS in acute MI patients was associated with worse clinical outcomes during hospitalization and at 1-year follow-up. These unfavorable outcomes highlight the need for a close follow-up of these patients and for timely therapeutic strategies to best manage these coexisting conditions.

BACKGROUND: Proximal cap ambiguity is a key parameter in the global chronic total occlusion (CTO) percutaneous coronary intervention (PCI) crossing algorithm. METHODS: We examined the baseline characteristics and procedural outcomes of 9718 CTO PCIs performed in 9498 patients at 41 US and non-US centers between 2012 and 2022. RESULTS: Proximal cap ambiguity was present in 35% of CTO lesions. Patients whose lesions had proximal cap ambiguity were more likely to have had prior coronary artery bypass graft surgery (37% vs. 24%; p < 0.001). Lesions with proximal cap ambiguity were more complex with higher J-CTO score (3.1 ± 1.0 vs. 2.0 ± 1.2; p < 0.001) and lower technical (79% vs. 90%; p < 0.001) and procedural (77% vs. 89%; p < 0.001) success rates compared with nonambiguous CTO lesions. The incidence of major adverse cardiovascular events (MACE) was higher in cases with proximal cap ambiguity (2.5% vs. 1.7%; p < 0.001). The retrograde approach was more commonly used among cases with ambiguous proximal cap (50% vs. 21%; p < 0.001) and was more likely to be the final successful crossing strategy (29% vs. 13%; p < 0.001). The antegrade dissection and re-entry (ADR) "move-the-cap" techniques were also more common among cases with proximal cap ambiguity. CONCLUSIONS: Proximal cap ambiguity in CTO lesions is associated with higher utilization of the retrograde approach and ADR, lower technical and procedural success rates, and higher incidence of in-hospital MACE.

BACKGROUND: Coronary artery perforation is one of the most feared and common complications of chronic total occlusion (CTO) percutaneous coronary intervention (PCI). METHODS: To assess the usefulness of the recently developed PROGRESS-CTO (NCT02061436) perforation risk score in independent cohorts. Individual patient-level data pooled analysis of three registries was performed. RESULTS: Of the 4566 patients who underwent CTO PCI at 25 centers, 196 (4.2%) had coronary artery perforation. Patients with perforations were older (69 ± 10 vs. 65 ± 10, p < 0.001), more likely to be women (19% vs. 13%, p = 0.009), more likely to have a history of prior coronary artery bypass graft (34% vs. 20%, p < 0.001), and unfavorable angiographic characteristics such as blunt stump (62% vs. 48%, p < 0.001), proximal cap ambiguity (52% vs. 34%, p < 0.001), and moderate-severe calcification (60% vs. 49%, p = 0.002). Technical success was lower in patients with perforations (73% vs. 88%, p < 0.001). The area under the receiver operating characteristic curve of the PROGRESS-CTO perforation risk model was 0.76 (95% confidence interval [CI], 0.72-0.79), with good calibration (Hosmer-Lemeshow p = 0.97). We found that the CTO PCI perforation risk increased with higher PROGRESS-CTO perforation scores: 0.3% (score 0), 2.3% (score 1), 3.1% (score 2), 5.5% (score 3), 7.5% (score 4), 14.6% (score 5). CONCLUSION: Given the good discriminative performance, calibration, and the ease of calculation, the PROGRESS-CTO perforation score may facilitate assessment of the risk of perforation in patients undergoing CTO PCI.
RESUMEN
BACKGROUND: There is limited data on complications associated with the use of coronary embolic protection devices (EPDs). METHODS: We queried the Manufacturer and User Facility Device Experience database between November 2010 and November 2020 for reports on coronary EPDs: Spider FX (Medtronic, Minneapolis, MN) and Filterwire EZ (Boston Scientific, Natick, MA). RESULTS: We retrieved 119 reports on coronary EPD failure (Spider FX n = 33 and Filterwire EZ n = 86), most of which (78.2%) occurred during saphenous vein graft interventions. The most common failure mode was inability to retrieve the EPD (49.6%), with the filter trapped against stent struts in 76.2% of the cases. Other device complications included filter fracture (28.6%), failure to cross (7.6%), failure to deploy (7.6%), and failure to recapture the filter (3.4%). Filter fracture (54.5 vs. 29.1%) and failure to recapture (9.1 vs. 2.1%) were more commonly reported, while failure to deploy the filter (0 vs. 10.5%) was less commonly reported with the Spider-FX. CONCLUSIONS: The most common modes of failure of coronary EPDs are the failure of retrieval (49.6%), followed by the filter fracture (28.6%). When using EPDs, careful attention to the technique is essential to avoid failures and subsequent complications.

OBJECTIVES: To examine the trends in utilization and outcomes of tricuspid valve (TV) transcatheter edge-to-edge repair (TEER). BACKGROUND: Surgery for isolated tricuspid regurgitation is associated with high morbidity and mortality and is rarely performed. TV TEER is an attractive alternative. METHODS: The Nationwide Readmissions Database was queried using the International Classification of Diseases, 10th Revision, procedure code for TV TEER for years 2016-2019. The main outcomes were trends in utilization and in-hospital all-cause mortality. RESULTS: We identified 918 hospitalizations for TV TEER. There was an uptrend in its utilization from 13 cases in the first quarter of 2016 to 122 cases in the last quarter of 2019 (p trend < 0.001). Concomitant mitral valve (MV) TEER was performed in 42.1% of admissions. The overall in-hospital mortality was 2.1%. Surgical TV replacement was needed in 1.1% of admissions; none of them died during the index hospitalization. Unplanned rehospitalizations were common at 30 days (15.7%); 38.2% of those were due to heart failure. There was no difference in in-hospital mortality between isolated TV TEER and combined MV and TV TEER (1.7% vs. 2.6%, p = 0.359). However, admissions receiving combined procedure had lower length of stay and urgent readmission rate. CONCLUSION: The current study showed that there was an increase in the utilization of TV TEER over 2016-2019 in the United States. TV TEER was associated with low rates of in-hospital mortality; however, the rate of urgent readmission remains high, mainly due to heart failure.

BACKGROUND: Transesophageal echocardiogram (TEE) is the preferred imaging modality to guide transcatheter left atrial appendage closure (LAAC). Intracardiac echocardiography (ICE) has evolved as a less invasive alternative to TEE. Several observational studies have shown similar success rates and perioperative complications between TEE and ICE for LAAC. OBJECTIVES: We sought to examine the temporal trends and patient characteristics of TEE versus ICE use in LAAC using a national database. We also evaluated hospital outcomes including periprocedural complications, mortality, and length of hospital stay. METHODS: This is a retrospective analysis of data from the National Readmission Database, collected from 2016 to 2018. The primary outcome was major adverse events (MAE) defined as in-hospital mortality, cardiac arrest, pericardial effusion with or without tamponade, pericardiocentesis or window pericardiocentesis and pericardial window, pericardial effusion and tamponade, and hemorrhage requiring transfusion. RESULTS: Trend analysis showed that TEE-guided LAAC increased from 96.6% in 2016 to 98.4% in 2018 (relative increase, 1.9%), while ICE-guided LAAC decreased from 3.4% to 1.6% during the same period (relative decrease, 53%, p for trend = 0.08). In the unmatched cohorts, the MAE was significantly lower in TEE-guided LAAC compared to ICE-guided LAAC (6.5% vs. 9.3%, p = 0.022). In the propensity score matching analysis, MAE remained significant (5.6% vs. 9.4%, p < 0.001). The incidence of pericardial effusion with or without tamponade remained significantly lower in the TEE group (2.3% vs. 5.8%, p < 0.001). Length of stay (3.4 vs. 1.9 days, p < 0.001) and hospitalization cost ($34,826 vs. $20,563, p < 0.001) remained significantly lower for TEE-guided LAAC. CONCLUSIONS: Compared to ICE, the incidence of MAE was significantly lower for TEE-guided LAAC, driven mainly by less pericardial effusion events. Large-scale randomized trials are needed to confirm the findings of the current and previous studies.

OBJECTIVE: To compare the clinical outcomes after extraplaque (EP) versus intraplaque (IP) tracking in chronic total occlusion (CTO) percutaneous coronary intervention (PCI). BACKGROUND: The impact of modern dissection and reentry (DR) techniques on the long-term outcomes of CTO PCI remains controversial. METHODS: We performed a systematic review and meta-analysis of studies that compared EP versus IP tracking in CTO PCI. Odds ratios (ORs) with 95% confidence intervals (CIs) are calculated using the Der-Simonian and Laird random-effects method. RESULTS: Our meta-analysis included seven observational studies with 2982 patients. Patients who underwent EP tracking had significantly more complex CTOs with higher J-CTO score, longer lesion length, and more severe calcification and had significantly longer stented segments. During a median follow-up of 12 months (range 9-12 months), EP tracking was associated with a higher risk of major adverse cardiovascular events (MACE) (OR 1.50, 95% CI (1.10-2.06), p = 0.01) and target vessel revascularization (TVR) (OR 1.69, 95% CI (1.15-2.48), p = 0.01) compared with IP tracking. There was no difference in the incidence of all-cause death (OR 1.37, 95% CI (0.67-2.78), p = 0.39), myocardial infarction (MI) (OR 1.48, 95% CI (0.82-2.69), p = 0.20), stent thrombosis (OR 2.09, 95% CI (0.69-6.33), p = 0.19), or cardiac death (OR 1.10, 95% CI (0.39-3.15), p = 0.85) between IP and EP tracking. CONCLUSION: EP tracking is utilized in more complex CTOs and requires more stents. EP tracking is associated with a higher risk of MACE, driven by a higher risk of TVR at 1 year, but without an increased risk of death or MI compared with IP tracking. EP tracking is critically important for contemporary CTO PCI.

BACKGROUND: There are limited data describing gender differences in patients undergoing chronic total occlusion (CTO) percutaneous coronary interventions (PCI). METHODS: We compared baseline clinical and angiographic characteristics and procedural outcomes between men and women among 9457 CTO PCIs performed at 38 centers between 2012 and 2022. RESULTS: A total of 7687 (81%) men and 1770 (19%) women were treated. Women were older, more likely to have comorbidities such as diabetes, hypertension and peripheral arterial disease, and had higher left ventricular ejection fraction. The most common CTO target vessel was the right coronary artery for both men (53%) and women (52%), although the left anterior descending artery was more frequently the target vessel among women (31% vs. 25%; p < 0.001). The J-CTO score (2.4 ± 1.3 vs. 2.2 ± 1.2; p < 0.001) as well as the PROGRESS-CTO score (1.3 ± 1.0 vs. 1.1 ± 1.0; p < 0.001) were higher among men. In female patients, antegrade wiring was more frequently the initial crossing strategy (87.6% vs. 82.4%; p < 0.001) and was more successful in crossing the target lesion (62.7% vs. 54.0%; p < 0.001) compared with men. Interventions in men required longer procedure time and fluoroscopy time, as well as higher air kerma radiation dose and contrast volume when compared to women. Technical (89% vs. 86%; p < 0.001) and procedural (87% vs. 84%; p = 0.003) success rates were higher among women. In-hospital major adverse cardiovascular events (MACE) were also higher in women (2.9% vs. 1.8%; p < 0.001). CONCLUSIONS: Women undergoing CTO PCI had higher technical and procedural success rates, but also higher in-hospital MACE compared with men.

BACKGROUND: The use of intravascular lithotripsy (IVL) in chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has received limited study. METHODS: We analyzed the baseline clinical and angiographic characteristics and procedural outcomes of 82 CTO PCIs that required IVL at 14 centers between 2020 and 2022. RESULTS: During the study period, IVL was used in 82 of 3301 (2.5%) CTO PCI procedures (0.4% in 2020 and 7% in 2022; p for trend < 0.001). Mean patient age was 69 ± 11 years and 79% were men. The prevalence of hypertension (95%), diabetes mellitus (62%), and prior PCI (61%) was high. The most common target vessel was the right coronary artery (54%), followed by the left circumflex (23%). The mean J-CTO and PROGRESS-CTO scores were 2.8 ± 1.1 and 1.3 ± 1.0, respectively. Antegrade wiring was the final successful crossing strategy in 65% and the retrograde approach was used in 22%. IVL was used in 10% of all heavily calcified lesions and 11% of all balloon undilatable lesions. The 3.5 mm lithotripsy balloon was the most commonly used balloon (28%). The mean number of pulses per lithotripsy run was 33 ± 32 and the median duration of lithotripsy was 80 (interquartile range: 40-103) seconds. Technical and procedural success was achieved in 77 (94%) and 74 (90%) cases, respectively. Two (2.4%) Ellis Class 2 perforations occurred after IVL use and were managed conservatively. CONCLUSION: IVL is increasingly being used in CTO PCI with encouraging outcomes.

Direct oral anticoagulants (DOACs) are being increasingly used in patients with chronic thromboembolic hypertension (CTEPH), however, the data on their safety and efficacy are scarce and contradictory. We systematically searched MEDLINE and Google Scholar databases from January 2010 to January 2021 for studies of DOACs in CTEPH. Three observational studies, 2 abstracts and one case series met our inclusion criteria. While these studies reported similar or even less rates of major bleeding in patients receiving DOACs compared with vitamin K antagonists, there were concerns about the possibility of increased risk of venous thromboembolism recurrence with DOAC therapy. Further studies are warranted to better define the role of DOACs in CTEPH.

BACKGROUND: There is a paucity of literature on safety and efficacy of various transseptal puncture (TSP) needles. OBJECTIVES: To assess the reported mechanisms of failure, complications, and outcomes among the most frequently used transseptal needles in the United States. METHODS: We queried the Food and Drug Administration (FDA) Manufacturer and User Facility Device Experience (MAUDE) database between January 2011 and January 2021 for reports on the most commonly used transseptal needles: NRG (Baylis Medical, Montreal, Canada), and BRK (St. Jude, Saint Paul, MN)]. The primary outcome was the mechanism of failure. Secondary outcomes included clinical consequences of device failure. RESULTS: The final analysis included 306 reports of failure/complication with TSP needles (NRG n = 70, BRK n = 236). The most commonly reported mode of failure was detachment of the needle component (i.e., clip, hub, stopcock, shaft, spring, or needle tip) (14.7% overall; 17.8% BRK; and 4.3% NRG). Among these reports, cardiac perforation was the most common complication (69.9% overall; 69.1% for BRK; and 72.9% for NRG). Pericardiocentesis was the second most commonly reported complication (45.1% overall; 48.3% for BRK; and 34.3% for NRG). The procedure was successfully completed in 33.3% of all cases (36.4% for BRK and 22.9% for NRG), while surgical conversion was needed in (13.4% overall; 14% for BRK and 11.4% for NRG) of the reports. Death occurred in 3.9% of all cases overall (3.4% for BRK and 5.7% for NRG). CONCLUSIONS: Needle detachment was the most common mode of failure, and cardiac perforation was the most common complication reported with TSP needles. Future efforts should focus on innovative TSP needle design, best practice guidelines, including role of imaging guidance, and increased TSP training.

INTRODUCTION: The comparative efficacy and safety of valve-in-valve transcatheter aortic valve replacement (ViV-TAVR) and redo-surgical AVR (redo-SAVR) in patients with degenerated bioprosthetic aortic valves remain unknown. METHOD: Digital databases were searched to identify relevant articles. Unadjusted odds ratios for dichotomous outcomes were calculated using a random effect model. A total of 11 studies comprising 8326 patients (ViV-TAVR = 4083 and redo-SAVR = 4243) were included. RESULTS: The mean age of patients undergoing ViV-TAVR was older, 76 years compared to 73 years for those undergoing SAVR. The baseline characteristics for patients in ViV-TAVR vs. redo-SAVR groups were comparable. At 30-days, the odds of all-cause mortality (OR 0.45, 95% CI 0.30-0.68, p = .0002), cardiovascular mortality (OR 0.44, 95% CI 0.26-0.73, p = .001) and major bleeding (OR 0.29, 95% CI 0.15-0.54, p = .0001) were significantly lower in patients undergoing ViV-TAVR compared to redo-SAVR. There were no significant differences in the odds of cerebrovascular accidents (OR 0.91, 95% CI 0.52-1.58, p = .74), myocardial infarction (OR 0.92, 95% CI 0.44-1.92, p = .83) and permanent pacemaker implantation (PPM) (OR 0.54, 95% CI 0.27-1.07, p = .08) between the two groups. During mid to long-term follow up (6-months to 5-years), there were no significant differences between ViV-TAVR and redo-SAVR for all-cause mortality, cardiovascular mortality and stroke. ViV-TAVR was, however, associated with higher risk of prosthesis-patient mismatch and greater transvalvular pressure gradient post-implantation. CONCLUSION: ViV-TAVR compared to redo-SAVR appears to be associated with significant improvement in short term mortality and major bleeding. For mid to long-term follow up, the outcomes were similar for both groups.

OBJECTIVE: The authors aimed to investigate the benefits and risks of catheter-directed thrombolysis (CDT) in acute deep venous thrombosis (DVT). BACKGROUND: The role of CDT in the management of DVT is evolving. Data on CDT versus anticoagulation alone in acute DVT is sparse. METHODS: We performed a systematic review and meta-analysis of published studies that compared CDT to anticoagulation alone in patients with acute DVT. RESULTS: We included 11 studies (four randomized control trials [RCTs] and seven observational studies) with a total of 8,737 patients. During hospital stay, patients who received CDT had higher odds of major bleeding (2.5% vs. 1.6%; OR 1.46, 95% CI [1.07, 1.98], p = .02), blood transfusion (10.8% vs. 6.2%; OR 1.8, 95% CI [1.52, 2.13], p < .001), and thromboembolism (15.5% vs. 10%; OR 1.67, 95% CI [1.47, 1.91], p < .001) compared with anticoagulation alone. At 6-month follow-up, patients who received CDT had higher venous patency (71.1% vs. 37.7%; OR 5.49, 95% CI [2.63, 11.5], p < .001) and lower postthrombotic syndrome (PTS; 27% vs. 40.7%; OR 0.44, 95% CI [0.22, 0.86], p = .02). During a mean follow-up duration of 30.5 ± 28 months, CDT group continued to have higher venous patency (79.6% vs. 71.8%; OR 3.79, 95% CI [1.54, 9.32], p = .004) and lower PTS (44.7% vs. 50.5%; OR 0.43, 95% CI [0.23, 0.78], p = .006), but no difference in thromboembolism. CONCLUSION: Compared with anticoagulation alone, CDT for patients with acute DVT was associated with a higher risk of complications, but a higher rate of venous patency and lower risk of postthrombotic syndrome at 2.5 years follow-up.

BACKGROUND: There is a paucity of data regarding the outcomes of transcatheter aortic valve replacement (TAVR) versus surgical aortic valve replacement (SAVR) among solid-organ transplant recipients. METHODS: Temporal trends in hospitalizations for aortic valve replacement among solid-organ transplant recipients were determined using the National Inpatient Sample database years 2012-2017. Propensity matching was conducted to compare admissions who underwent TAVR versus SAVR. The primary outcome was in-hospital mortality. RESULTS: The analysis included 1,730 hospitalizations for isolated AVR; 920 (53.2%) underwent TAVR and 810 (46.7%) underwent SAVR. TAVR was increasingly utilized for solid-organ transplant recipients (Ptrend = 0.01), while there was no change in the number of SAVR procedures (Ptrend = 0.20). The predictors of undergoing TAVR for solid-organ transplant recipients included older age, diabetes, and prior coronary artery bypass surgery, while TAVR was less likely utilized in small-sized hospitals. TAVR was associated with lower in-hospital mortality after matching (0.9 vs. 4.7%, odds ratio [OR] 0.19; 95% confidence interval [CI] 0.11-0.35, p < .001) and after multivariable adjustment (OR 0.07; 95% CI 0.03-0.21, p < .001). TAVR was associated with lower rate of acute kidney injury, acute stroke, postoperative bleeding, blood transfusion, vascular complications, discharge to nursing facilities, and shorter median length of hospital stay. There was no difference between both groups in the use of mechanical circulatory support, hemodialysis, arrhythmias, or pacemaker insertion. CONCLUSION: This contemporary observational nationwide analysis showed that TAVR is increasingly performed among solid-organ transplant recipients. Compared with SAVR, TAVR was associated with lower in-hospital mortality, complications, and shorter length of stay.

OBJECTIVES: To examine the outcomes of vascular brachytherapy (VBT) for recurrent drug-eluting stents (DES) in-stent restenosis (ISR). BACKGROUND: Recurrent DES-ISR can be challenging to treat. VBT has been used with encouraging results. METHODS: We report the long-term outcomes of patients with recurrent DES-ISR treated with VBT between January 2014 and September 2018 at a tertiary care institution. The main outcome was target lesion failure (TLF), defined as the composite of clinically driven target lesion revascularization (TLR), target lesion myocardial infarction (MI), and target lesion-related cardiac death. Cox proportional hazards analysis was performed to identify variables associated with recurrent TLF. RESULTS: During the study period, 116 patients (143 lesions) underwent VBT. Median follow-up was 24.7 (14.5-35.4) months. The incidence of TLR, target-lesion MI, and TLF was 18.9%, 5.6%,and 20.1% at 1 year, and 29.4%, 10.5%, and 32.9% at 2 years.Initial presentation with acute coronary syndrome (ACS) was independently associated with TLF (hazard ratio = 1.975, 95% CI [1.120, 3.485], p = .019). Lesions treated with intravascular ultrasound (IVUS) guidance had a lower incidence of TLR (14.3% vs. 39.6%, log-rank p = .038), and a trend toward lower incidence of TLF (19% vs. 42.6%, log-rank p = .086). CONCLUSIONS: VBT can improve the treatment of recurrent DES-ISR, but TLF occurs in approximately one in three patients at 2 years. Initial presentation with ACS was associated with higher TLF and the use of IVUS with a trend for lower incidence of TLF.

OBJECTIVE: To evaluate the impact of COVID-19 pandemic migitation measures on of ST-elevation myocardial infarction (STEMI) care. BACKGROUND: We previously reported a 38% decline in cardiac catheterization activations during the early phase of the COVID-19 pandemic mitigation measures. This study extends our early observations using a larger sample of STEMI programs representative of different US regions with the inclusion of more contemporary data. METHODS: Data from 18 hospitals or healthcare systems in the US from January 2019 to April 2020 were collecting including number activations for STEMI, the number of activations leading to angiography and primary percutaneous coronary intervention (PPCI), and average door to balloon (D2B) times. Two periods, January 2019-February 2020 and March-April 2020, were defined to represent periods before (BC) and after (AC) initiation of pandemic mitigation measures, respectively. A generalized estimating equations approach was used to estimate the change in response variables at AC from BC. RESULTS: Compared to BC, the AC period was characterized by a marked reduction in the number of activations for STEMI (29%, 95% CI:18-38, p < .001), number of activations leading to angiography (34%, 95% CI: 12-50, p = .005) and number of activations leading to PPCI (20%, 95% CI: 11-27, p < .001). A decline in STEMI activations drove the reductions in angiography and PPCI volumes. Relative to BC, the D2B times in the AC period increased on average by 20%, 95%CI (-0.2 to 44, p = .05). CONCLUSIONS: The COVID-19 Pandemic has adversely affected many aspects of STEMI care, including timely access to the cardiac catheterization laboratory for PPCI.

There is a paucity of data on the outcomes and revascularization strategies for critical limb ischemia (CLI) among patients with chronic kidney disease (CKD). Hence, we conducted a nationwide analysis to evaluate the trends and outcomes of hospitalizations for CLI with CKD. The National Inpatient Sample database (2002-2015) was queried for hospitalizations for CLI. The trends of hospitalizations for CLI with CKD were reported, and endovascular versus surgical revascularization strategies for CLI with CKD were compared. The main study outcome was in-hospital mortality. The analysis included 2,139,640 hospitalizations for CLI, of which 484,224 (22.6%) had CKD. There was an increase in hospitalizations for CLI with CKD (Ptrend = 0.01), but a reduction in hospitalizations for CLI without CKD (Ptrend = 0.01). Patients with CLI and CKD were less likely to undergo revascularization compared with patients without CKD. CLI with CKD had higher rates of in-hospital mortality (4.8% vs 2.5%, adjusted odds ratio (OR) 2.01; 95% CI 1.93-2.11) and major amputation compared with no CKD. Revascularization for CLI with CKD was associated with lower rates of mortality (3.7% vs 5.3%, adjusted-OR 0.78; 95% CI 0.72-0.84) and major amputation compared with no revascularization. Compared with endovascular revascularization, surgical revascularization for CLI with CKD was associated with higher rates of in-hospital mortality (4.7% vs 2.7%, adjusted-OR 1.67; 95% CI 1.43-1.94). In conclusion, this contemporary observational analysis showed an increase in hospitalizations for CLI among patients with CKD. CLI with CKD was associated with higher in-hospital mortality compared with no CKD. Compared with endovascular therapy, surgical revascularization for CLI with CKD was associated with higher in-hospital mortality.
