With increasing procedural volumes, recognizing anatomical risk factors, especially the proximity between the LAA and PA, has become essential for interventional cardiologists. This report emphasizes the value of detailed pre-procedural imaging, such as cardiac CT or TEE, to assess LAA morphology, PA diameter, and their spatial relationship. Identifying anatomical variants like Type II proximity can guide appropriate device selection and procedural planning. The study also highlights the importance of post-procedural vigilance, particularly in patients with elevated PA pressure or larger closure devices. Sudden hemodynamic deterioration after LAAC should raise suspicion for PA injury, and timely pericardiocentesis or surgical intervention may be life-saving. By combining anatomical awareness, careful technique, and close monitoring, clinicians can reduce the risk of this serious complication and improve patient outcomes.","order":5,"name":"Ethics","group":{"name":"EthicsHeading","label":"Impact on daily practice"}}]}}
