Objective: To evaluate structure‐oriented left ventricular volume reduction surgery (LVVRS). The purpose of this study was to report the early and mid‐term results of left volume reduction surgery for dilated cardiomyopathy (DCM). Methods: We performed LVVRS on 29 patients with DCM. The age of the patient ranged from 8 to 73 years (mean 58 ± 18 years). There were 19 male patients (63%). Twenty‐three patients were ischemic, 5 were non‐ischemic, and 1 had salcoidosis. Twenty‐three patients were in New York Heart Association class III or IV. Fourteen patients underwent the Dor operation, 11 underwent a septal anterior ventricular exclusion operation, and 6 underwent a modified Batista operation. Fifteen patients underwent mitral annuloplasty and 2 patients had mitral valve replacement. All patients were divided into two groups, a Dor group (n = 14) and non‐Dor group (n = 15). Postoperative early results and mid‐term survival rate were compared between the two groups. Results: Hospital mortality was 13.8% (4/29). The causes of death were low‐output syndrome (n = 3) and septic shock (n = 1). Survival rate was 80% at 1 year and 72% at 3 years. Two‐year survival rate of Dor and non‐Dor groups were 69.8% and 93.8%, respectively (p = 0.099). Conclusions: Early and mid‐term results of LVVRS were satisfied, and the non‐Dor operation tended to be superior in mid‐term survival to the Dor operation. Long‐term follow‐up is warranted.
