Percutaneous closure of left atrial appendage to prevent embolic events in high-risk patients with chronic atrial fibrillation

2009

Background: Percutaneous closure of the left atrial appendage (LAA) is a novel alternative for the treatment of patients with atrial fibrillation (AF) and with a high risk of stroke who are not eligible for long-term anticoagulation therapy. The aim of this study was to asses the safety, feasibility, and long-term efficacy of this procedure. Methods: From July 2004 to June 2007, 20 patients (13 male, mean age 69 ± 8 years) with non–valvular AF (NV-AF) underwent LAA percutaneous closure using the PLAATO™ system, implanted through a transeptal access. All patients had contraindications to anticoagulant therapy and were at high risk for cardioembolic stroke (mean CHADS2 score 3 ± 1.2). A trans…

Safety and efficacy of left atrial appendage occlusion with the ACP or Watchman device guided by intracardiac echocardiography from the left atrium

2021

Abstract Background There is a paucity of randomized data regarding the safety and efficacy of the use of intracardiac echocardiography (ICE) from the left atrium (LA) to guide left atrial appendage occlusion (LAAO) procedures under local anesthesia using either of the available devices. Hypothesis The aim of this study was to compare the efficacy and safety of ICE from the LA with transesophageal echocardiography (TEE) for guidance during transcatheter LAAO procedures. Methods Single‐center, cohort study of patients undergoing LAAO with the Amplatzer Cardiac Plug or Watchman device. Procedures were guided by ICE from the LA with local anesthesia (n = 175) or TEE under general anesthesia (n…

Left Atrial Remodeling and Brain Natriuretic Peptide Levels Variation after Left Atrial Appendage Occlusion

2021

Background: Few data are available about brain natriuretic peptide (BNP) variation and left atrial remodeling after the left atrial appendage occlusion (LAAO) technique. Methods: Prospective study included all consecutive patients successfully implanted with an LAAO device. Contrast-enhanced cardiac computed tomography (CT) was performed before and 6 weeks after the procedure with reverse left atrial remodeling defined by an increase in LA volume &gt
