OBJECTIVES:To summarize the experience of surgical repair of ruptured sinus of Valsalva aneurysm to right atrium and to compare the difference between through right atrium repair and transaortic combined with right atrium approach.METHODS:Between January 2004 and December 2009, 53 patients with ruptured sinus of Valsalva aneurysm to right atrium underwent surgical repair. There were 35 male and 18 female, aged from 15 to 63 with a mean of (33 ± 9) years. Repair through right atrium had undergone in 40 patients (group I), while transaortic combined with right atrium approach in 13 patients (group II). Surgical results between the two group and group were compared in cardiopulmonary bypass time, clamp aorta time, mechanical ventilation time, ICU time and postoperative stay time.RESULTS:There were no significant differences between two groups in cardiopulmonary bypass time [(86 ± 29) min vs. (96 ± 30) min], clamp aorta time [(59 ± 29) min vs. (71 ± 25) min], mechanical ventilation time [(9 ± 4) h vs. (16 ± 23) h], ICU time [(35 ± 23) h vs. (35 ± 23) h], postoperative stay time [(7.1 ± 0.9) d vs. (7.7 ± 2.8) d] (P > 0.05). Follow-up was performed from 1 to 64 months, with a mean of (32 ± 21) months. There was no death during follow up. One needed operation due to severe aortic valve regurgitation. One combined with coronary artery disease used medication. Heart function (NYHF) of the other patients were I and II degree during follow up.CONCLUSIONS:Surgical repair of ruptured sinus of Valsalva aneurysm to right atrium shows good result. There is no significant difference between through right atrium repair and transaortic combined with right atrium approach.

OBJECTIVE:To summarize the experience in surgical treatment of De Bakey type III aortic dissection and discuss the operative indications, techniques, and methods for spinal cord protection.METHODS:From January 1994 to January 2000, 49 patients with De Bakey type III aortic dissection were operated on. Of these patients, 35 were subjected to partial thoratical aorta replacement, 4 partial thoratical aorta replacement and plasty, 8 total thoratical aorta replacement, and 2 thoracoabdominal aorta replacement. In the 35 patients, the operations were performed by using the technique which preserved blood was transfused back by pump via the femoral artery.RESULTS:Hospital mortality in this group was 6.1% (3/49). Eight patients received emergence operation, and 1 patient died. Paraparesis developed in one patient (2.0%). Other complications included re-exploration for bleeding in 3 patients, and wound infection in 5.CONCLUSIONS:The rate of mortality and complication is high in patients with De Bakey type III aortic dissection. Appropriate operative techniques and methods of spinal cord protection are essential to resolve this problem.

BACKGROUND:Although minimally invasive surgical procedures have aroused much interest in cardiac surgery, difficulty still exists with its application in most of the operations on great arteries. This report summarizes our initial experience of aortic root replacement by a superior ministernotomy in terms of operative indications, operative techniques, and potential benefits.METHODS:Between July 1999 and September 1999, 8 patients who were diagnosed with Marfan syndrome with aortic valve regurgitation underwent aortic root replacements with composite grafts. Clinical characteristics, in-hospital outcomes, and postoperative stay of these patients were compared with data of patients who had undergone Bentall procedure by standard median sternotomy from January to September 1999.RESULTS:There was no death in either group of patients. Demographics were similar between the two groups of patients. In the mini-incision group, the mediastinal drainage was significantly less than the standard incision group. The mean operating time was significantly longer than that in the standard incision group. The cardiopulmonary bypass time and aortic cross-clamping time were similar in both groups of patients. The mean intubation time, postoperative blood transfusion amount, duration of intensive care unit stay and postoperative hospital stay were less than that of the standard incision group; however, they all showed no statistical significant difference.CONCLUSIONS:Aortic root replacement by a superior ministernotomy in cardiopulmonary bypass with cannulas through the femoral artery and femoral vein or right atrium is a safe, reliable procedure with excellent exposure. The procedure provides a potential benefit of less trauma, quick recovery, and reduction of mediastinal drainage and reduction of blood transfusion.
