Key result
Rapid Watchman Flex deployment successfully controls acute bleeding from LAA perforation during angiography.
Why the study?
Pericardial effusion is a common complication of percutaneous LAA closure that often requires interrupting the intervention, highlighting the need to describe acute management strategies.
Case Report (n=1)
Rapid deployment of an LAA closure device can serve as an effective technique for bleeding control following LAA perforation during appendage angiography.
May offer bailout for LAA perforation; leaves open whether this extends beyond single-case observation.
Background Pericardial effusion is a common complication of percutaneous left atrial appendage (LAA) closure. Acute management is the cornerstone of pericardial effusion treatment and interrupting the intervention is often required. Case summary A 65-year-old man presented an acute 10 mm pericardial effusion following pigtail contrast appendage injection. A rapid Watchman Flex 24 mm (Boston Scientific) deployment permitted bleeding interruption. A needle pericardiocentesis was achieved in order to prevent any haemodynamical instability. Discussion This case report describes an atypical cause of pericardial effusion and a technique for bleeding control with LAA closure device deployment.

Champagne et al. (2021) conducted a case report in Pericardial effusion during left atrial appendage angiography (n=1). Watchman Flex 24 mm deployment and needle pericardiocentesis was evaluated. Rapid deployment of a 24 mm Watchman Flex device successfully controlled bleeding from an acute 10 mm pericardial effusion caused by LAA perforation during angiography.
