Long term follow up of left ventricular function after repair of left ventricular aneurysm

The aim of this study is to evaluate long term left ventricular function after repair of left ventricular aneurysm. Ninety-seven patients underwent repair of postinfarctional LV aneurysms, between 1992 and 2003. There were 86 patients males and 11 females. Sixty-one patients underwent linear closure and thirty-six patients had endoaneurysmorraphy. Their mean preoperative EFs were 38.9 % and 38.0 %, and the preoperative NYHA functional classes were 2.850.73 and 2.930.74, respectively . There was not significant difference between the groups with respect to age, gender, diseased coronary artery number, urgency of the procedure, preoperative LVEF, functional status, and comorbid risk factors. Postoperative early mortality after classical aneurysmectomy was 9.8% (n=6) and 2.7% (n=1) in the group with endoaneurysmorraphy. Eight-year (96-month) mortality rates were 12.7% (n=7) in the group with classic aneurysmectomy and 14.2% (n=5) in the group with endoaneurysmorraphy. The preoperative ejection fractions were 38.9% in the classical aneurysmectomy group and 38.0% in the endoaneurysmorraphy. Postoperatively, ejection fractions increased 42.8% and 45.0% after 96 months. In the group with classical aneurysmectomy and the group with endoaneurysmorraphy, preoperative and postoperative functional classes (NYHA) after 96 months were 2.6 and 1.6, and 2.7 and 1.2 respectively. Both linear and endoaneurysmorraphy techniques increases functional class postoperative long term.
