A new concept for correction of systolic anterior motion and mitral valve regurgitation in patients with hypertrophic obstructive cardiomyopathy

Abstract

a graft-assisted anastomosis between the ascending aorta and the supraceliac abdominal aorta. In our patient, a graft was implanted between the ascending and descending aortas. To avoid uncontrolled bleeding, there are 3 aspects that must be focused on perioperatively. First, all ductal tissue must be aggressively removed. Otherwise the anastomosis between the graft and the aorta will be susceptible to bleeding. Second, the anastomosis should be free of tension. Careful study of CT scans and better preoperative preparation are helpful to achieve complete dissociation of the descending aorta. More important, implanting a conduit will assist in reducing the tension. Third, pressuring hemostasis is effective when uncontrolled bleeding occurs. A bandage was placed with a little pressure on the stoma and thoracic cavity. One of the tips was placed out of the thoracic cavity. The bleeding volume was 900 mL on postoperative day 1 and 350 mL on postoperative day 2. The hemostasis
