Left ventricular outflow tract pseudoaneurysm diagnosed with point-of-care ultrasound in the emergency department

CJEM. 2018 Sep;20(5):798-801. doi: 10.1017/cem.2018.20. Epub 2018 Mar 16.


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.
