Abstract: Objective To evaluate the treatment efficacy of post-infarction left ventricular pseudo-aneurysm (LVPA) through surgical procedure, and explore the diagnosis and differential diagnosis details of LVPA. Methods Between May 1993 and July 2007, 7 cases were diagnosed through echocardiography aided with left ventriculography or multi-sliced computer tomography (MSCT) or magnetic resonance imaging (MRI); 6 cases with LVPA were surgically treated through different procedure that included direct closure, cut and patching or cut and sandwiching procedure choose according to its location, anatomical morphology, and comorbidity; accompanied diseases were treated by coronary artery bypass grafting(CABG) procedure. Results Six cases were diagnosed before surgery, and 1 case was diagnosed during the surgical procedure. One died from the cardiac tamponade due to rupture of LVPA before the surgical procedure, so the inhospital mortality was 14.3%（1/7）. There was no operative death. With the follow-up from 2 months to 13 years of the 6 operational survivors, 1 case died from cardiac rupture and pericardial tamponade 4 years after the repair procedure. Of the 5 surviving LVPA, the left ventricular ejection fraction(LVEF) values were from 43% to 52%, and 3 cases were in New York Heart Association (NYHA) class Ⅰ, and 2 cases were in NYHA class Ⅱ. Conclusion Echocardiography, aided with left ventriculography or MSCT or MRI, is an effective measure for diagnosis of LVPA. Surgical procedure is an effective measure to treat LVPA,but different surgical procedures, accompanied with homeochronous CABG procedure,should be adopted to deal with LVPA according its location, anatomical morphology, and accompanied deformity. The perioperative and mid-long term efficacy were good for the surgical treatment of LVPA, but it is imperative to pay attention to prevention of the recurrence and the late rupture of repaired LVPA. 
