Embolized Watchman Removal With Modified Hangman Technique

J Soc Cardiovasc Angiogr Interv. 2024 May 18;3(8):102072. doi: 10.1016/j.jscai.2024.102072. eCollection 2024 Aug.

Abstract

In this case report, we explore a novel technique to remove an embolized Watchman device (Boston Scientific) into the thoracic aorta endovascularly. The technique involves a wire + snare combination that is threaded through the metal struts of the Watchman. This combination technique along with the threading provides increased stability during removal and decreases the risk of the Watchman slipping from the devices and causing further embolization. Further work is required to elucidate the efficacy of this technique in other scenarios.
