Despite decades of experience, catheter ablation of an accessory atrioventricular pathway (AP) in the posteroseptal region can still be challenging owing to complex anatomy and the proximity to coronary arteries. This is especially true for APs involving the musculature around the proximal coronary sinus (CS), the middle cardiac vein, or a diverticulum off the CS [1]. The coronary venous system…
An innovative mapping and ablation catheter (Sphere-9TM, Medtronic) fully integrated into a novel mapping and ablation platform (AfferaTM, Medtronic) was introduced (1,2). The lattice-tip irrigated…
PVC response Atrial-Pace (PVC-A-Pace) is a programmable algorithm developed by Abbott to prevent pacemaker-mediated tachycardia after premature ventricular contractions (PVCs) in all dual-chamber cardiac implantable…
Early recurrence of atrial arrhythmia (ERA) is commonly seen after catheter ablation of atrial fibrillation (AF), with reported incidence of up to 61% in the…
Pulmonary vein isolation (PVI) is the cornerstone of atrial fibrillation (AF) ablation. A blanking period (BP) of 3 months is used in clinical trials and…
The availability of dual-chamber leadless pacemakers (LPs) expands the use of this technology for patients who need atrial pacing and reliable atrioventricular synchrony.1 Although the…
A 44-year-old man with a structurally normal heart presented with a history of regular palpitations. He was not on any medication and his baseline electrocardiogram…
With advances in technology and technique, catheter ablation has achieved increasing safety and efficacy in arrhythmia treatment. Simultaneously, innovations have been developed to expedite patient…
Pulsed Field Ablation (PFA) employs high-voltage electroporation for tissue ablation, offering enhanced durability and minimized esophageal damage, thereby improving PVI safety (1). Electrical arcing is…
In response to Drs. Cheng and Zhang to our paper1, we note that despite ARVC being a relatively uncommon cardiomyopathy, we uniquely report on a…
Sir, we read Zado’s study1 with great interest. The objective of this study was to determine the type, prevalence, outcome, and risk correlates of atrial…
