Summary: The goal of this clinical trial is to evaluate the effect of catheter ablation of persistent atrial fibrillation on cognitive function in patients with mild cognitive impairment. Participants will be randomized into antiarrhythmic drugs alone or atrial fibrillation ablation + antiarrhythmic drugs.

Summary: To investigate the effect of VTA ablation at the time of LVAD implant to see if it can reduce the incidence of VTA after surgery

Summary: In this pilot and feasibility study, the investigators will enroll patients with frequent symptomatic episodes of atrial fibrillation (AF) in a cross-over study testing two different classes of anti arrhythmic drugs (AADs). This pilot and feasibility study will provide preliminary data for a larger study in which the investigators will test the hypothesis that a common AF genetic risk allele modul...

Summary: Therapeutic management of Atrial Fibrillation (AF) is based either on heart rate control or on rhythm control, a strategy which aims to maintain a normal heart rhythm. The benefit in terms of morbidity and mortality of a normal heart rhythm would, however, be largely offset by the frequent side effects of antiarrhythmic drugs which could even lead to an increase in mortality compared to rate contr...

Summary: Sudden cardiac death (SCD) due to recurrent ventricular tachycardia (VT) is an important clinical sequela in patients with structural heart disease. VT generally occurs as a result of electrical re-entry in the presence of arrhythmogenic substrate (scar). Scar tissue forms due to an ischemic cardiomyopathy (ICM) from prior coronary obstructive disease or a non-ischemic cardiomyopathy (NICM) from a...
