Importance Little is known about cardiac adverse events among patients with nonobstructive
coronary artery disease (CAD). Objective To compare myocardial infarction (MI) and …

Objectives: This study sought to evaluate the efficacy and safety of using half-normal saline
(HNS) as the cooling radiofrequency ablation (RFA) irrigant among patients who had failed …

Background—Little is known about the contemporary use of intra-aortic balloon pump (IABP)
and other mechanical circulatory support (O-MCS) devices in patients undergoing …

Background: High-grade atrioventricular block (H-AVB) is a well-described in-hospital
complication of transcatheter aortic valve replacement (TAVR). Delayed high-grade …

Background Prior research has shown a transient increase in the incidence of acute
myocardial infarction (AMI) after daylight savings time (DST) in the spring as well as a …

Background—Bleeding after hospital discharge from percutaneous coronary intervention
(PCI) is associated with increased risk of subsequent myocardial infarction (MI) and death; …

Innovations in radiofrequency (RF) ablation and nonablative techniques have led to
significant advances in addressing complex arrhythmogenic substrates for a variety of …

Background Ventricular tachyarrhythmias are the most common cause of death in patients
with repaired tetralogy of Fallot (TOF), but predicting those at risk remains a challenge. An …

Background: Data on atrial fibrillation (AF) ablation and outcomes are limited in patients with
congenital heart disease (CHD). We aimed to investigate the characteristics of patients with …

Introduction While cardiac sarcoidosis (CS) carries a risk of ventricular arrhythmias (VAs)
and sudden cardiac death (SCD), risk stratification of patients with CS and preserved left …
