Novel automated atrial pacemapping technique based on intracardiac pattern matching to identify the location of ectopic atrial activity

Atrial ectopy from the pulmonary veins and non-pulmonary vein foci can trigger atrial fibrillation. In addition, the elimination of atrial ectopy is important to prevent recurrence. The intracardiac pattern matching technique has been reported as …

Severe ST-segment elevation and AV block during pulsed-field ablation due to vasospastic angina — a novel observation

Catheter ablation of atrial fibrillation using non-thermal electroporation represents a promising ablation modality due to its believed superior safety profile. Still, if electroporation is delivered in proximity to a coronary artery, vasospasms …

Therapeutic potential of conduction system pacing as a method for improving cardiac output during ventricular tachycardia

Hemodynamic compromise in ventricular tachycardia (VT) does not arise solely from rapid heart rates because sinus tachycardia and supraventricular tachycardias, at similar rates, generally cause less compromise. One contributor is the loss of …

Pulsed field ablation for atrial fibrillation when in proximity to LAA AtriClip: the LAA-Clip does not inhibit the pulse

Pulsed field ablation (PFA) is a novel, non-thermal ablation technology to treat atrial fibrillation (AF). PFA has caught great interest because of its unique safety and efficacy profile, e.g., the myocardial tissue selectivity and the advantage …

Redefining cardiac care: the promising horizon of epicardial pulse field ablation for postoperative atrial fibrillation

We know from knowledge of anatomy that the cardiac GP is located in three main areas: the retroatrial GP, the annular ventricular GP in the oblique sinus, and the peri-great vessel GP in the transverse sinus [ 5 , 6 ]. Musikantow et al. describe …
