Posterobasal left ventricular aneurysms: surgical treatment and long-term outcomes.

Abstract

This retrospective study analyzes short- and long-term outcomes in 18 patients who underwent repair of posterobasal left ventricular aneurysm from January 1993 through December 2009. As concomitant procedures, mitral reconstruction was performed in 4 patients, ventricular septal defect repair in 2 patients, and coronary artery bypass grafting in 17 patients. In regard to surgical technique, 10 patients underwent patch repair and 8 underwent closure by linear suture. The in-hospital mortality rate was 11% (2 patients). An intra-aortic balloon pump was placed postoperatively in 1 patient. One patient underwent reoperation for mediastinitis and 2 for bleeding. The 1-, 5-, and 10-year survival rates were 82%, 76%, and 52%, respectively. Posterobasal left ventricular aneurysm repair can be performed with low short-term mortality rates and good long-term outcomes. It must be judged whether a linear repair or patch repair is better, in accordance with aneurysm size and the concomitant operative procedure, if any.
