Volume reduction surgery for end-stage ischemic heart disease.
The Dor procedure, or infarction excision surgery, was first used in 1984. It is a surgical treatment option for patients with end-stage ischemic heart failure. In a recently published multicenter study that included a total of 439 patients, average ejection fraction increased from 29 +/- 10% to 39 +/- 12% after surgery. In our experience, the overall survival rate 18 months after surgery is 89%, and the preoperative mortality rate is 6.6%. These results are similar to the previous reports from Dor's group, which confirmed the certain value of the surgery. Echocardiography, including intraoperative transesophageal echocardiography, plays an important role in clarifying cardiac anatomies, absolute left ventricular (LV) volumes, ejection fraction, and mitral regurgitation in patients with ischemic heart failure undergoing this surgery. With the development of ultrasound and computer technology, three-dimensional echocardiography may be preferred when evaluating the surgical results, including determination of absolute LV volumes. Communication between experienced cardiac surgeons and echocardiographers in the operating room is essential for successful outcomes and reliable evaluation of the surgery.
