Left atrial wall thickness variability measured by CT scans in patients undergoing pulmonary vein isolation

Left Atrial Wall Thickness Variability Measured by CT Scans. Introduction: Successful catheter ablation of atrial fibrillation (AF) requires the creation of transmural lesions in the left atrium (LA). In addition, cardiac perforation is more likely to occur in areas of thin walls. The LA wall thickness is thus relevant both for procedural efficacy and safety. This study sought to evaluate the regional LA wall thickness in patients with AF.

Increased perforation risk with an MRI-conditional pacing lead: a single-center study.

Magnetic resonance imaging (MRI) has been considered contraindicated in patients with cardiac pacemakers (PPMs). Recently, Medtronic (MDT) MRI SureScan PPM (Medtronic Inc., Minneapolis, MN, USA) and leads were introduced into clinical practice in the United States of America.

Characteristics of Responders to Cardiac Resynchronization Therapy: The Impact of Echocardiographic Left Ventricular Volume

One‐third of patients who receive cardiac resynchronization therapy (CRT) are classified as nonresponders. Characteristics of responders to CRT have been studied in multiple clinical trials.

UTILIZATION OF AN ADVANCED ABLATION LESION ANNOTATION SYSTEM WITH FORCE SENSING CATHETERS DRAMATICALLY REDUCES ADENOSINE INDUCED PULMONARY VEIN RECONNECTION FOLLOWING RADIOFREQUENCY ABLATION FOR ATRIAL FIBRILLATION

The ability to achieve transmural, durable ablation lesions is a significant challenge of a pulmonary veins isolation (PVI) procedure resulting in their reconnection. We aim to assess the effect of utilization of a force-sense irrigated tip catheters in conjunction with a novel automated ablation
