title: Progressive increase in peridevice leakage after the implantation of the watchman device on long-term serial echocardiographic follow-up.
abstract: Percutaneous left atrial appendage (LAA) occlusion using the Watchman device (Atritech, Plymouth, MN) is suggested as an alternative modality to warfarin for stroke prevention in patients with nonvalvular atrial fibrillation (AF). However, peridevice leakage resulting from incomplete LAA occlusion remains 1 of the most frequent limitations. We report a case of progressive increase in peridevice leakage after Watchman device implantation on long-term transesophageal echocardiographic follow-up accompanied by stroke.
