Pulmonary artery injury (PAI) is a feared yet rare complication of endocardial LAAC, but its surrounding literature is scarce.</p><p><strong>Objectives: </strong>The aim of the current study was to review prior PAI published reports and the U.S. Food and Drug Administration Manufacturer and User Facility Device Experience (MAUDE) database to understand evidence and mechanisms of PAI after LAAC.</p><p><strong>Methods: </strong>A systematic review was conducted of the literature and MAUDE database for previously reported cases of PAI, and cases were reviewed for patient characteristics and outcomes.

Most commonly, LAAC associated with PAI involved a dual-seal (75%) followed by lobular occlusive devices (19.4%); the device was unspecified in 2.8% of cases. PAI commonly presented postprocedurally, either within the first 24 hours (50%) or beyond (38.9%), with cardiac tamponade (61.1%) or cardiac arrest (19.4%). Overall, 52.8% required surgery with or without antecedent pericardiocentesis, and 16.7% were managed with pericardiocentesis. PAI was associated with a high mortality rate (ie, 33.3%). Unfortunately, no specific cardiac imaging or procedural details to predict PAI were noted in the reports.</p><p><strong>Conclusions: </strong>Presentation of PAI after LAAC can occur immediately following the procedure or be delayed.
