ABSTRACT
OBJECTIVE:
To describe a 10-year experience with surgical treatment of left ventricular aneurysm and compare the results of linear repair and ventricular reconstruction.DESIGN:
A retrospective data analysis.SETTING:
Department of cardiothoracic surgery. PATIENTS All patients treated with concurrent coronary artery bypass revascularization and surgical repair of ventricular aneurysm from 1985 to 1995.METHODS:
Patients underwent either linear repair after aneurysmectomy (group A; n=51) or reconstruction of the left ventricle using a patch (group B, n=10). Preoperative patient characteristics and postoperative mortality and symptomatic results in the two groups were compared with chi(2) and paired "t"-tests.RESULTS:
The early mortality rates were 9.8% overall, 7.8%, in group A, and 20% in group B. During a mean follow-up of 58 months, the late mortality rates were 34.5%, 38.2%, and 12.5%. In comparison to patients in group A, those in group B had higher preoperative rates of seriously impaired left ventricular ejection fraction (p=0.01) and pathologic left ventricular end-diastolic pressure (p=0.03) and a prolonged operative aortic cross-clamp time (p=0.04). Early mortality in group B may have been influenced by the initially impaired hemodynamic function and the cross-clamp time. In the longterm, patients in group B had more symptomatic improvement than those in group A (p=0.02).CONCLUSIONS:
Ventricular function in patients with left ventricular aneurysm improved after ventricular reconstruction using a patch. Further experience with this procedure should improve postoperative survival and long-term prognosis.
