Abstract:
A case of left ventricular pseudoaneurysm formation at an atypical site in the left ventricle is described. A 32-year-old man underwent mitral valve replacement and he was taken to the intensive care unit (ICU) in good condition. Two hours later, he sustained massive bleeding from the chest drainage tubes, hypotension, and shock. We reopened the sternotomy in the ICU and found massive bleeding from the lateral wall of the left ventricle. Under cardiopulmonary bypass and cardiac arrest, the myocardial laceration was closed with Teflon felt-buttressed interrupted sutures and then the involved area was covered with a Xeno-medicaTM patch. Postoperative echocardiography, computed tomography, and left ventriculography revealed pseudoaneurysm formation at antero-lateral wall of left ventricle. Because the patient was asymptomatic, he was discharged from our hospital without reoperation. However we are closely following him in the outpatient clinic.
