Concomitant aortic valve and ascending aorta replacement with moderate hypothermic circulatory arrest to treat an aortic bicuspid valve with post-stenotic dilatation.
ABSTRACT We recommend concomitant surgery for aortic valve replacement (AVR) and ascending aortic replacement using moderate hypothermic circulatory arrest (CA) for post-stenotic dilatation complicated by an aortic bicuspid valve. Cardiopulmonary bypass (CPB) was established from the right atrium to the dilated ascending aorta. As soon as the rectal temperature decreased to 28 °C, CA was commenced and the open distal anastomosis of a polyester prosthesis, without any cerebral perfusion, was completed. AVR was then carried out during rapid re-warming with CPB using a side arm of the prosthesis. This procedure exhibited safe and satisfactory results. There are many benefits of carrying out the procedure in this way; it avoids the requirement for cannulation to a calcified aortic arch, provides a good operative field, for an easier distal anastomosis and suturing at the valve site, and reduces the risk of further dilatation or dissection of the residual ascending aorta in the later phase.

ABSTRACT: To evaluate the effectiveness of tailoring aortoplasty used to treat fusiform aneurysms of the ascending aorta, we reviewed the results of operation in 17 patients. Nine patients had tailoring aortoplasty alone, and 8 patients had aortoplasty with Dacron wrap of the ascending aorta. Fourteen of 17 patients were discharged from the hospital, and 12 patients were alive at follow-up between 2 and 120 months. Of two late deaths, neither was due to aneurysmal disease. Actuarial survival at 1 and 10 years was 81% and 63%, respectively. In selected cases, tailoring aortoplasty can achieve long-term results comparable with those of resection and graft replacement of fusiform ascending aortic aneurysms.The Annals of Thoracic Surgery 03/1995; 59(2):497-51. · 3.63 Impact Factor

ABSTRACT: Among 119 cases of fatal dissecting aneurysm of the aorta, exclusive of those iatrogenically caused or associated with arachnodactyly or aortic stenosis, there were observed 11 cases of congenital bicuspid aortic valve (9%). The ages ranged from 17 to 69 years, five of the patients being 29 years old or younger. Among the latter, three had coarctation of the aorta and one had Turner's syndrome without coarctation. In one of the older patients, aortic insufficiency was present. Hypertension was either established or inferred from cardiac weight in 73% of the cases. In each case, cystic medial necrosis of the aorta was present. Prolapse of valves other than the aortic was observed in 45% of the cases with bicuspid aortic valve. Compared to an estimated incidence of bicuspid aortic valve of about 1 to 2% in the population, the high incidence among subjects with dissecting aneurysm suggests a causative relationship between bicuspid aortic valve and aortic dissecting aneurysm.Circulation 06/1978; 57(5):1022-5. · 14.95 Impact Factor
