Left ventricular outflow tract pseudoaneurysms are a rare but life-threatening disorder, often caused by complications of cardiac surgery or myocardial infarction. We present a case report of a patient with no prior risk factors who presented with a six-month history of progressive exertional dyspnea, bilateral leg swelling and cough. Point-of-care ultrasound revealed an unexpected outpouching of the left ventricle. He was diagnosed with a left ventricular outflow tract pseudoaneurysm and subsequently went into cardiogenic shock secondary to extension of pseudoaneurysm causing extrinsic compression of the coronary arteries. The patient underwent successful emergency surgical repair and made a full recovery.
左心室流出道假性动脉瘤是一种罕见但危及生命的疾病,通常由心脏手术或心肌梗死的并发症引起。我们报告了一例无既往危险因素的患者,其病史为六个月的进行性劳力性呼吸困难、双侧腿部肿胀和咳嗽。即时超声心动图显示左心室有一处意外膨出。患者被诊断为左心室流出道假性动脉瘤,随后因假性动脉瘤的扩展导致冠状动脉的外部压迫而发生心源性休克。患者成功接受了紧急外科修复手术,并完全康复。
