[Suspected Left Ventricular Pseudo-false Aneurysm of a Huge Size Combined with Sustained Ventricular Tachycardia;Report of a Case].

A 74-year-old man was transferred to our hospital for heart failure and ventricular tachycardia. Left ventricular aneurysm of a huge size( 6×9 cm) was found on the imaging test, and was suspected to be a pseudo-false aneurysm because of its thick wall with small orifice. Occulusion of the right coronary artery (#1) was revealed by coronary arteriography and the diskinetic aneurysm in the inferior wall was revealed by left ventriculography. The surgical treatment was needed, because of the high risk of rupture. He successfully underwent Dor operation with endocardial cryoablation and left ventricular ejection fraction (LVEF) was found to be improved by postoperative left ventriculography. He discharged on 56 days after operation. Ventricular pseudo-false aneurysm is rare and the treatment is controversial.
