Abstract:
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.
