Reconstructive surgery for an akinetic anterior ventricular wall in ischemic cardiomyopathy.
BACKGROUND
The purpose of this prospective study is to analyze the postoperative outcome after only left ventricular reconstruction (LVR) versus LVR combined with coronary artery bypass grafting (CABG) and/or mitral valve (MV) procedure in ischemic cardiomyopathy (ICM) as a result of an akinetic anterior ventricular wall.


RESULTS
Nineteen patients underwent only LVR, and 37 underwent a concomitant LVR procedure. In both groups, New York Heart Association (NYHA) classification improved significantly from 3.5 +/- 0.6 to 2.2 +/- 0.5 (LVR group) and 3.4 +/- 0.7 to 2.5 +/- 0.5 (combined LVR group). Ejection fraction improved significantly from 25.1 +/- 3.2 to 35.3 +/- 4.5% in the LVR group and 28.1 +/- 2.2 to 37.6 +/- 5.5% in the combined LVR group. Cardiac index improved significantly from 1.8 +/- 0.6 to 2.3 +/- 0.5 l/min/m2 in the LVR group and 1.6 +/- 0.4 to 2.2 +/- 0.6 l/min/m2 in the combined LVR group. An additional concomitant procedure increased the mortality rate only slightly. The overall 1- and 5-year actuarial survival rates were 90% and 75% in the LVR group and 80% and 70% in the combined LVR group.


CONCLUSIONS
The LVR for akinetic ventricular wall shows very satisfactory early and long-term results. The LVR, with or without concomitant procedures, has considerable benefits for operative therapy.
