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.
