Patients with congenital structural heart disease (CSHD) and inherited arrhythmias (IAs) are at high risk of ventricular tachyarrhythmias and sudden cardiac death. The present study was designed to evaluate the short- and long-term outcomes of patients with CSHD and IA who received a wearable cardioverter-defibrillator (WCD) for the prevention of sudden(More)
BACKGROUND Patients with atrial fibrillation sustain a significant lower exercise tolerance compared to those in sinus rhythm, even while seemingly in adequate rate-control. METHODS Exercise testing was performed during atrial fibrillation and after electric cardioversion for 30 patients who were initially treated with AV modifying agents and were(More)
As the longevity of patients with congenital heart disease improves, the number surviving to adulthood will continue to rise. Consequently, practicing physicians can expect to encounter an increasing number of adult patients with various congenital cardiac conditions. Impaired exercise tolerance in this patient population is exceptionally common; adult(More)
BACKGROUND Percutaneous pulmonary valve implantation using a stent-based bioprosthetic valve provides an alternative to surgery in select patients. Systemic infections in Melody valve-implanted patients with and without identified valve involvement have been reported, yet the incidence is unknown, and risk factors remain unidentified. METHODS AND RESULTS(More)
BACKGROUND Women with congenital long-QT syndrome experience an increased risk for cardiac events after the onset of adolescence that is more pronounced among carriers of the LQT2 genotype. We hypothesized that the hormonal changes associated with menopause may affect clinical risk in this population. METHODS AND RESULTS We used a repeated-events analysis(More)
BACKGROUND Subpulmonary ventricular outflow conduits are utilized routinely to repair complex congenital cardiac abnormalities, but are limited by the inevitable degeneration and need for reintervention. Data on conduit durability and propensity to dysfunction in the adult population are limited. METHODS The study included 288 consecutive patients ≥18(More)
OBJECTIVES The aim of this study was to evaluate whether certain post-Maze left atrial (LA) contractile profiles may pose a risk for ischemic stroke. BACKGROUND The mechanical contraction of the left atrium may be modified after the Maze procedure. Whether this imposes a risk for stroke, even in the presence of sinus rhythm and after removal of the LA(More)
AIMS Absent left atrium (LA) mechanical contraction may occur following the modified Cox-maze operation, and was found to impose a potential risk for the occurrence of thrombo-embolic stroke. It is unknown whether certain morphological P-wave characteristics can surrogate absent LA mechanical activity. The aim of this study was to evaluate the morphological(More)
OBJECTIVES We aimed to evaluate the management and outcomes of patients of the octogenarian age group with non-ST elevation myocardial infarction (NSTEMI) in a real-world setting. METHODS The risk of 30-day and 1-year mortality by age and the time of coronary angiography [categorized as early (≤48 h of admission) and late (>48 h of admission)] was(More)
OBJECTIVES This study hypothesized that time-dependent statin therapy will reduce the risk of life-threatening ventricular tachyarrhythmias among patients with nonischemic cardiomyopathy (NICM) enrolled in the MADIT-CRT (Multicenter Automatic Defibrillator Implantation Trial with Cardiac Resynchronization Therapy). BACKGROUND Prior studies suggested that(More)
