Abstract 3254: Effectiveness of Surgical Ventricular Restoration in Patients With Different Shape Abnormalities following Myocardial Infarction
Myocardial infarction leaves a spectrum of LV shape abnormalities. Surgical Ventricular Restoration(SVR) can be applied to any but there are no data that relates its effectiveness to pre-op LV shape. Aim. To assess cardiac function and survival following SVR in patients with different post-MI shape abnormalities. Methods. Ninety-eight patients (69 ± 9yrs) submitted to SVR for heart failure and/or angina. LV shape was classified by Echo 2CH: Type 1 (true aneurysm): LV shape is geometrically delimited by two “borders” identified by an abrupt change in curvature; Type 2 (Intermediate): shape is delimited by one “border” most often at the inferior region; Type 3 (dilated cardiomyopathy): LV shape is without borders ( i.e. the curvature is flattened along the overall LV perimeter). Results. Average FUP was 23 ± 13 months. Table 1⇓ and Graph show that all types benefit from SVR and survival is not significantly different. Conclusions. This study relates the effectiveness of SVR to shape abnormalities and demonstrate that results are good not only in the true aneurysm but also in dilated cardiomyopathy (type 2 and 3).
