Left ventricular wall resection for aneurysm and akinesia  due to coronary artery disease: fifty consecutive patients.
Left ventricular wall resection with or without vein bypass grafting was performed in 50 consecutive patients with aneurysm or an akinetic segment with poor left ventricular hemodynamics. Ejection fraction averaged 29% and left ventricular end-diastolic pressure averaged 20 mm Hg. Associated valve disease was present in 14 patients (28%). Hospital mortality was 22% (11 patients) and late mortality was 20% (10 patients). The lowest mortality (3%, 1 death) was found in patients who had anterior apical resection with associated vein bypass, in whom prophylactic balloon pumping was used when needed for ejection fractions of less than 30%. A high mortality occurred with associated valve replacement (6 deaths, 86%) and posterior aneurysm. Among 39 patients followed for an average of twenty-four months, 34 (87%) improved one class and 18 (46%) improved two classes of the New York Heart Association Functional Classification.
