Objective To summarize the experiences of surgical treatment for post infarction ventricular aneurysm and mi tral regurgitation， thus to improve surgical curative effect and survival rates . Clinical data of 37 patients with myocardial infarction complicated with ven tricular aneurysm and severer than moderate mitral regurgitation were retrospectively an alyzed between December 2000 and June 2007, all 37 patients underwent coron ary artery bypass grafting and reconstruction of left ventricular after aneurysm resection, mitral valve repair or replacement. Results Three patients died during hospital stay after surgery,mortality rate was 81%, of th em two died in renal failure, one died in brain complications.Thirty patients we re followed up, followup rate was 88.2%(30/34), with 4 patients missed. Follow up time ranged from 1 month to 6 years after surgery, 2 patients died in foll o wup period, of them one died in anticoagulant treatment failure complicated w ith the large cerebral infarction, one died of lung infection and heart failure. The inner diameter of le ft atrium and enddiastolic left ventricle reduced obviously than those before operation （30.1±3.5mm vs.39.3±3.7mm, P=0.004;48.4±4.3mm vs.61.2±5.1mm, P=0.003）by color doppler echocardiography examination at 6th month a fter su rgery.There was no obvious change in size of untouched ventricular aneurysm(diam eter lt;5cm). No regurgitation or slight regurgitation were observed in 12 patient s, mild regurgitation was observed in 2 patients and moderate in 1 patients. Conclusion According to different types of post infarctio n ventricular aneurysm and mitral regurgitation, constitution o f different surgical treatment programs, can result in favorable early and long-term curative effect. There’s marked improvement in most patients’cardiac f unction and survival rate.
