Successful WATCHMAN Device Placement Despite Left Atrial Appendage Perforation in Two Cases

Sangeeta Prabhakar Bhat et al. Cureus. .

Abstract

The WATCHMAN (Boston Scientific, Marlborough, USA) is a device used to occlude the left atrial appendage (LAA) in patients of non-valvular atrial fibrillation (NVAF) with a high CHA2DS2-VASc score who are poor candidates for oral anticoagulation. LAA perforation is a well-known complication of the WATCHMAN device placement. Here we present two cases of NVAF where oral anticoagulation was not advisable due to recurrent bleeding episodes. They underwent the WATCHMAN procedure for stroke prevention. During the placement of the WATCHMAN device into the left atrial appendage (LAA) in both cases, pericardial staining was noted that worsened over the next few minutes. It was decided to deploy the 27 mm WATCHMAN device into the LAA. In one case, satisfactory hemostasis was achieved with the device deployment eliminating the need for cardiothoracic surgery. However, the second case led to pericardial tamponade and was managed by the placement of a pericardial window. To our knowledge, this is the first case series describing the use of a WATCHMAN device upon detection of LAA perforation.

Keywords: device deployment; hemostasis; left atrial appendage perforation; pericardial staining; pericardial tamponade; watchman.

Cardiac catheterization images of the first case demonstrate satisfactory positioning of the pigtail catheter into the intact left atrial appendage (LAA) (1A), pericardial staining (red arrows) with the advancement of the catheter into the anterior lobe of LAA prior to WATCHMAN device placement (1B) achievement of satisfactory hemostasis after device deployment (1C).

Cardiac catheterization images of the second case demonstrate the satisfactory positioning of the pigtail catheter into the intact left atrial appendage (2A), pericardial staining (red arrows) during WATCHMAN device deployment (2B), and worsening pericardial effusion after device deployment (2C).
