In Vitro Evaluation of Ice-Cold Saline Irrigation Introduction Irrigated radiofrequency (RF) catheters allow tissue-electrode interface cooling, decreasing thrombus risk while enabling higher RF power delivery. The impact of irrigation with ice-cold

The incidence of pulmonary vein reconnection and recurrent atrial fibrillation after a single catheter ablation procedure is unacceptably high. We studied the ability of a novel endoscopic laser balloon ablation system (EAS) to achieve acute and chro

Transesophageal echocardiography (TEE) is the gold standard in the evaluation for left atrial appendage (LAA) thrombus in patients with atrial fibrillation (AF) and is often performed prior to AF ablation. We routinely use intracardiac echocardiograp

Background Conventional mapping of ventricular tachycardia (VT) after myocardial infarction is limited in patients with hemodynamically untolerated or noninducible VT. Objectives The purpose of this study was to develop a unique strategy using noncon

Objectives: To characterize a new method for radiofrequency energy titration during ablation of atrial tissue based on reduction in electrogram amplitude. To compare this method with energy titration using electrode thermometry.

Introduction: The production of larger, particularly deeper lesions may improve the success rate for radiofrequency (RF) ablation of post infarction ventricular tachycardia (VT). Therapeutic RF ablation causes left ventricular (LV) mural swelling. Th

The contractile power of the latissimus dorsi muscle (LDM) is used in skeletal muscle cardiac assist (SMCA) to augment the blood pumping ability of a failing heart. The LDM has three anatomically distinct, independently innervate segments-the transve
