Aneurysms of the inferior left ventricular
wall comprise only a small fraction of all aneurysms that have
been reported in surgical series. Pseudo-false ventricular aneurysm
is very rare and communicates with the left ventricule through
a small orifice, and its wall contains myocardial tissue, unlike
false ventricular aneurysm. A 53-year-old man was admitted to
our hospital with chest pain. Echocardiography revealed left
ventricular aneurysm, and the coronary arteriography subsequently
revealed a complete occlusion of right coronary #2 and 75% and
90% stenosis of left anterior descending artery #7 and#8, respectively.
Left ventriculography revealed an aneurysm of the inferior left
ventricular wall, which communicated with the left ventricle
through a small orifice and exhibited contraction. Surgical repair
was indicated. Endoventricular circular patch repair (Dor operation)
of the aneurysm of the inferior left ventricular wall and coronary
artery bypass grafting to the left anterior descending artery
and the right coronary artery were simultaneously performed under
cardiopulmonary bypass with moderate hypothermia. The postoperative
course was uneventful and the patient was discharged on the 22th
day after surgery. Pseudo-false ventricular aneurysm of the inferior
left ventricular wall was diagnosed by pathologic examination.
