Abstract:
A 57 year-old female was admitted for chronic heart failure (HF) with NYHA class IV symptoms. Transthoracic echocardiography revealed ruptured left ventricular (LV) lateral and posterior wall between their basal and middle segments resulting in giant, round pseudoaneurysm formation with a diameter of 12 cm. Bidirectional flow through a 2.9 cm orifice between the LV and the pseudoaneurysm cavity was shown. A 12-cm diameter pseudoaneurysm was resected and the orifice was closed with a Dacron patch. Twelve months after the diagnosis, the patient is in a stable condition with NYHA class II HF symptoms.
