Percutaneous LAAO and Pulsed-Field Isolation in a Canine Model
In this study, we investigated the feasibility, safety, and efficiency of using a novel device system to perform percutaneous left atrial appendage occlusion concomitant with left atrial appendage electrical isolation (LAAEI) via pulsed field ablation. In the acute phase, LAAEI was successful in 10 of 10 canines. At follow-up, full endothelialization was observed in 5 of 5 (100%) cases at 6 months. LAAEI was durable in 8 of 10 (80.00%) canines. Histologic examination in 4 of 6 LAAs with durable isolation showed transmural scars comprising fibrosis and fat. No pericardial effusion or phrenic paralysis was observed at follow-up. This preliminary study provides the scientific basis for first-in-human studies.
期刊介绍：
JACC: Basic to Translational Science is an open access journal that is part of the renowned Journal of the American College of Cardiology (JACC). It focuses on advancing the field of Translational Cardiovascular Medicine and aims to accelerate the translation of new scientific discoveries into therapies that improve outcomes for patients with or at risk for Cardiovascular Disease. The journal covers thematic areas such as pre-clinical research, clinical trials, personalized medicine, novel drugs, devices, and biologics, proteomics, genomics, and metabolomics, as well as early phase clinical trial methodology.
