Chronic aortic counterpulsation with latissimus dorsi: clinical follow-up cardiomyoplasty comparison

摘要

Dynamic aortomyoplasty is an alternative technique to heart transplantation. The goal of our study was to evaluate the benefits of aortic counterpulsation obtained by dynamic aortomyoplasty in patients with heart failure refractory to pharmacological treatment and contraindications to heart transplant or cardiomyoplasty.In this study we compared preoperative and postoperative data of selected patients submitted who were treated with dynamic thoracic aortomyoplasty. This surgical technique wrap the right latissimus dorsi muscle flap around the ascending aorta. This muscle flap was electrically stimulated during diastole, following a muscle-conditioning protocol, to obtain diastolic augmentation. At twelve months follow-up period we evaluated, invasively and noninvasively, the hemodynamic and clinical effects of aortomyoplasty. We observed a significant decrease in the number of hospitalizations (p
