  • Aortic Cusps Replacement with Bovine Pericardium for bicuspid aortic valve and Severe Aortic Regurgitation

    ObjectiveTo assess clinical results of aortic cusps replacement with bovine pericardium for bicuspid aortic valve (BAV) and severe aortic regurgitation (AR). MethodsClinical data of 79 patients with BAV and severe AR who underwent aortic cusps replacement with bovine pericardium in Wuhan Asia Heart Hospital from June 2008 to December 2013 were retrospectively analyzed. There were 60 male and 19 female patients with their age of 38±14 years (ranged 12-78 years). All the patients were in NYHA class Ⅱ. There were 26 patients with ascending aorta and sinotubular expanding. ResultsNo early death or major complication was recorded. Intraoperative transesophageal echocardiography showed successful repair with normal coaptation of the aortic leaflets in all the patients. AR grade was less than mild in all the patients with peak aortic valve pressure gradients of 14.2±2.8 mm Hg. All the patients were discharged from the hospital within 15 postoperative days without any adverse symptom, and were followed up for 50±16 months (ranged 9-64 months). During follow-up, all the patients were in NYHA classⅠ. There were 57 patients without AR, 16 patients with mild AR, 5 patients with moderate AR and 1 patients with severe AR. The peak of aortic valve pressure gradient was 12.4±3.2 mm Hg. The average diameter of ascending aorta was 2.7 cm in the patients with ascending aorta and sinotubular expanding. The shape of sinotubular kept normal. The height of coaptation of aortic valve was 0.58 cm by echocadiography. None of the patients died or required reoperation. The structural valve degeneration was not observed during the follow-up. ConclusionThree aortic cusps replacement with bovine pericardium can produce good hemodynamics and midterm results for patients with BAV and severe AR. The ascending aorta and sinotubular should be reduced and fixed in the patients with ascending aorta and sinotubular expanding.
