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: Higher rates of CIED implantations have been associated with an increased rate of lead failures and complications resulting in higher rates of transvenous lead extractions (TLE). OBJECTIVE: To assess the trends TLE admissions and evaluate the patient related predictors of safety outcomes. METHODS: National Readmission Database was queried to identify patients who underwent TLE from January 2016 to December 2019. We conducted a multivariate regression analysis to identify variables associated with in-hospital mortality in patients undergoing TLE. Additionally, we compared trends and outcomes of TLE among patients with prior sternotomy versus those without prior sternotomy and analyzed sex-based differences among patients undergoing TLE. RESULTS: We identified 30,128 hospitalizations for TLE. The index admission in-hospital mortality rate was 3.21% with cardiac tamponade happening in 1.46% of the admissions. Age, infective endocarditis, CKD, congestive heart failure and anemia were associated with higher in-hospital mortality rates. There was a lower rate of in-hospital mortality in patients with history of prior sternotomy versus patients without (OR 0.72, CI: 0.59-0.87, p-value < 0.001). There was no difference in in-hospital mortality rate between males and females. Females had a shorter length and a higher cost of stay when compared to male gender. CONCLUSION: TLE admissions continue to increase. Overall rates of mortality and complications are relatively low. Patients with prior sternotomy had better outcomes and less complications when compared to those without prior sternotomy. Female gender is associated with higher rates of cardiac tamponade, yet shorter length of stay with lower cost.

RESUMEN

AIMS: Despite increased temporary mechanical circulatory support (tMCS) utilization for acute myocardial infarction complicated by cardiogenic shock (AMI-CS), data regarding efficacy and optimal timing for tMCS support are limited. This study aimed to describe outcomes based on tMCS timing in AMI-CS and to identify predictors of 30-day mortality and readmission. METHODS AND RESULTS: Patients with AMI-CS identified in the National Readmissions Database were grouped according to the use of tMCS and early (<24 h) vs. delayed (≥24 h) tMCS. The correlation between tMCS timing and inpatient outcomes was evaluated using linear regression. Multivariate logistic regression was used to identify variables associated with 30-day mortality and readmission. Of 294 839 patients with AMI-CS, 109 148 patients were supported with tMCS (8067 veno-arterial extracorporeal membrane oxygenation, 33 577 Impella, and 79 161 intra-aortic balloon pump). Of patients requiring tMCS, patients who received early tMCS (n = 79 906) had shorter lengths of stay (7 vs. 15 days, P < 0.001) and lower rates of ischaemic and bleeding complications than those with delayed tMCS (n = 32 241). Patients requiring tMCS had higher in-hospital mortality [odds ratio (95% confidence interval)] [1.7 (1.7-1.8), P < 0.001]. Among patients requiring tMCS, early support was associated with fewer complications, lower mortality [0.90 (0.85-0.94), P < 0.001], and fewer 30-day readmissions [0.91 (0.85-0.97), P = 0.005] compared with patients with delayed tMCS. CONCLUSION: Among patients receiving tMCS for AMI-CS, early tMCS was associated with fewer complications, shorter lengths of stay, lower hospital costs, and fewer deaths and readmissions at 30 days.

RESUMEN

Coronary chronic total occlusions (CTO) are present in up to one-third of patients with coronary artery disease (CAD). It is thus essential for all clinical cardiologists to possess a basic awareness and understanding of CTOs, including optimal evaluation and management. While percutaneous coronary intervention (PCI) for CTO lesions has many similarities to non-CTO PCI, there are important considerations pertaining to pre-procedural evaluation, interventional techniques, procedural complications, and post-procedure management and follow-up unique to patients undergoing this highly specialized intervention. Distinct from other existing topical reviews, the current manuscript focuses on key knowledge relevant to non-interventional cardiologists.

RESUMEN

Background: Data on outcomes of patients with high-risk acute pulmonary embolism (PE) transferred from other hospitals are scarce. Methods: We queried the Nationwide Readmissions Database for admissions who were ≥18 years old, and with a primary discharge diagnosis of acute high-risk PE between the years 2016 and 2019. The main outcome of interest was the difference in all-cause in-hospital mortality between patients admitted directly to small/medium hospitals; patients admitted directly to large hospitals; and patients transferred to large hospitals. Results: Among 11,341 weighted hospitalizations with high-risk PE, 631 (5.6%) patients were transferred to large hospitals. There was no significant change in the rates of transfer during the study period. Transferred patients were younger and had a higher prevalence of comorbidities. They were more likely to present with saddle PE and cor pulmonale and were more likely to receive advanced therapies. In-hospital mortality was not different between patients transferred to large hospitals and those admitted directly to large hospitals (adjusted odd ratio [OR] 1.11, 95% confidence interval [CI] 0.81, 1.54) as well as between patients transferred to large hospitals and those admitted directly to small/medium hospitals (aOR 1.28, 95% CI 0.92, 1.76). The rates of major bleeding and cardiac arrest were higher among transferred patients. Admissions for transferred patients were associated with higher cost and longer length of stay. Conclusion: Transferred patients with high-risk PE were more likely to receive advanced therapies. There was no difference in-hospital mortality rates compared with patients admitted directly to the large or small/medium hospitals.

RESUMEN

Background: The impact of continuous positive airway pressure (CPAP) on cardiovascular outcomes among patients with obstructive sleep apnea (OSA) is controversial. Objective: To evaluate the impact of CPAP on reducing cardiovascular outcomes in patients with OSA. Methods: We performed a computerized search of MEDLINE, EMBASE and COCHRANE databases through April 2021 for randomized trials evaluating the impact of CPAP versus control on cardiovascular outcomes in patients with OSA. Summary estimates were reported using both fixed and random effects model. The main study outcome was major adverse cardiac events (MACE). Results: The final analysis included 8 randomized trials with total of 5684 patients. The weighted mean follow-up was 42.6 months. There was no difference between the CPAP and control groups in the risk of MACE (14.4% versus 14.8%, risk ratio [RR]: 0.97; 95% confidence interval [CI]: 0.85 to 1.10; p = 0.60; I2 = 21%). Subgroup analysis suggested that CPAP was associated with lower MACE (by 36%) in CPAP-adherent patients (≥4 h/night) (Pinteraction = 0.08). There was no difference between the CPAP and control groups in the risk of all-cause mortality, cardiovascular mortality, acute stroke, acute myocardium infarction or hospitalizations for angina. Conclusions and relevance: CPAP use might not be associated with lower cardiovascular events among patients with OSA. However, patients adherent to CPAP (≥4 h/night) might derive a benefit on cardiovascular outcomes. Future studies are warranted to evaluate the impact of CPAP in reducing cardiovascular events among patients with severe OSA and with optimal adherence rates to CPAP therapy.
