['Surgical restoration of the left ventricular wall (Dor procedure) has been advocated as a therapy for left ventricular dysfunction due to ischemic cardiomyopathy. This procedure involves placement of an endoventricular patch through a ventriculotomy.', 'We reviewed our series of patients that underwent the Dor procedure within the past 4 years and examined their pre and postoperative ventricular function and mitral valve function. Pre and postoperative ejection fraction and degree of mitral regurgitation were analyzed using the paired Student t-test. We hypothesized that this procedure would result in improved ventricular function and that it would also help improve mitral valve function.', 'Thirty-four patients underwent this procedure, with one death. Of these, 30 patients underwent concomitant coronary artery bypass grafting and 8 patients had mitral intervention (seven had an Alfieri repair of the mitral valve, and one had mitral valve annuloplasty). The average preoperative ejection fraction among these patients was 26.8% (range 10-45%). The postoperative ejection fraction was significantly higher at 35.4% (range 25-52%) (P <.001). We noted an improvement in ejection fraction in 27 patients (82%). We also noted that 21 of 33 patients (64%) had improvement in the degree of mitral regurgitation based on echocardiography data (P <.001).'] Does ventricular reconstruction result in improved left ventricular function and amelioration of mitral insufficiency?
