Abstract
Abstract
Background
Catheter ablation for atrial fibrillation may improve quality of life and long-term mortality among patients with heart failure.
Purpose
The rates of hospital readmission after catheter ablation for atrial fibrillation among patients with an established diagnosis of heart failure are largely unknown. We aimed to assess the rates and causes of 30-day readmission among patients with heart failure undergoing catheter ablation vs. medical therapy for atrial fibrillation in the United States.
Methods
The 2016 Nationwide Readmissions Database was screened for patients with diagnosis of heart failure and atrial fibrillation using the 10th Revision of International Classification of Diseases codes. Patients undergoing catheter ablation for atrial fibrillation were grouped separately from those treated medically for atrial fibrillation. Thirty-day readmissions were assessed for both groups.
Results
The analytical cohort included 749,776 (national estimate of 1,421,673) patients with heart failure and atrial fibrillation. This included 2,204 patients that underwent catheter ablation. Patients treated with catheter ablation had lower 30-day readmissions compared to the medical therapy group (16.8% vs 20.1%, p<0.001). Fifty-five percent of all readmissions among the catheter ablation cohort were related to cardiac events. Heart failure exacerbation (40%) and arrhythmia (36%) were the most common cardiac causes for readmission after catheter ablation (Figure).
Conclusions
In a contemporary nationwide analysis of patients with heart failure and atrial fibrillation, compared to medical therapy those treated with catheter ablation for atrial fibrillation had fewer 30-day readmissions after index hospital discharge. The most common cause for readmission among patients treated with catheter ablation was heart failure exacerbation and arrhythmia.

Abstract
Abstract
Introduction
Conduction disturbances after transcatheter aortic valve replacement (TAVR) requiring permanent pacemaker (PPM) implantation are a well-known procedural complication. Data on the effect of post-TAVR PPM implantation on 30-day readmissions is scarce.
Methods
The Nationwide Readmissions Database (NRD) is a nationally representative sample of all US hospitalizations, representing over 35 million discharges. The 2016 NRD was used to identify patients who underwent TAVR and PPM implantation from January to November 2016. Propensity matching was used to balance baseline clinical characteristics.
Results
Of the 44,607 patients who underwent TAVR, 4,878 (10.9%) required permanent pacemaker implantation during their index hospitalization. Patients requiring PPM during their index admission for TAVR had a higher crude median length of stay (LOS) (5d vs. 3d, p<0.001), median cost of index admission ($61,604 vs. $45,513, p<0.001) and rate of 30-day readmission (14.5% vs 11.2%, p<0.001). After 2:1 propensity matching, PPM patients still had a higher median LOS (5d vs. 3d, p<0.001), median cost of index admission ($61,902 vs. $41,162, p<0.001), and rate of 30-day readmission (13.8% vs 11.1%, p=0.003). Patients who received PPM were more likely to be older (81.1 vs 80.3, OR 1.01, CI 1.01–1.02), diabetic (OR 1.27, 1.13–1.44), obese (OR 1.22, 1.05–1.43), and have right (OR 4.35, 3.72–5.09) or left (OR 1.80, 1.51–2.15) bundle branch blocks on multivariate analysis. Causes of readmission in patients with and without PPM were predominantly non-cardiac (62.9% vs 68.0%). Heart failure was the most common cause of readmission for both groups (18.4% vs 14.6%). Median cost of readmissions ($8716 vs $8250, p=0.34) and LOS (4d vs 4d, p=1) were not significantly different during readmissions.
Conclusions
Based on a nationally representative sample, 10.9% of patients undergoing TAVR required PPM implantation during the index hospitalization. Age, diabetes, obesity, and right or left bundle branch blocks were significant predictors of PPM implantation. PPM implantation resulted in significantly higher LOS, costs, and 30-day readmissions on propensity-matched analysis.

P6572Sinus arrest post-cardioversion. Eur Heart J 2019.

Abstract
Abstract
Introduction
Sinus arrest remains a recognized but likely underreported complication of cardioversion, with incidence ranging widely in the literature, from virtually 0% to 1.5%. After a case of elective cardioversion resulting in the need for ECMO support, we investigated possible risk factors that could help predict adverse outcomes after cardioversion.
Hypothesis
Cardioversion, while generally benign, is not without risks, and further study may help elucidate predictors of morbidity and mortality.
Methods
We retrospectively reviewed data of all patients who underwent cardioversion at three hospitals within the Lifespan health system, Rhode Island Hospital, Newport Hospital, and the Miriam Hospital, between 2000 and 2015. 23 patients who experienced sinus arrest after cardioversion, and characteristics of these patients were compared with those of 3:1 age-and-gender matched controls using binomial logistic regression analysis on Stata.
Results
Of 12,156 patients who underwent cardioversion, 23 patients (57% male, mean age 78±14), or 0.18%, experienced immediate post-cardioversion sinus arrest, defined as absence of sinus activity for greater than five seconds. Compared with 3:1 age-and-gender-matched controls who underwent cardioversion without incident, binomial logistic regression revealed that paroxysmal atrial fibrillation (OR 11.8; 95% CI 1.85–75.72; p=0.009), beta-blocker use (OR 58.0; 95% CI 2.4–1404.48; p=0.013), Amiodarone use (OR 19.9; 95% CI 2.0–198.32; p=0.011), and elevated ventricular rate (CV 0.028; 95% CI 0.0031–0.053; p=0.027) were statistically significant predictors of sinus arrest after cardioversion. Calcium-channel blocker use, Digoxin use, age, gender, PR interval, QRS duration, and corrected QT interval were not significant associations.
Conclusions
Sparse data exists regarding characteristics predisposing patients to adverse outcomes following cardioversion, and further risk stratification is warranted, given the potential for significant morbidity and mortality. Our findings raise questions that demand elucidation, such as whether beta-blockers or Amiodarone should be held prior to cardioversion.
