Abstract:
Objective To evaluate the feasibility and safety of modified Yacoub technique with aortic annuloplasty in the patients with aortic root aneurysm and dilatation of aortic annular base. Methods We performed a retrospective review of 6 patients with aortic root aneurysm undergoing modified Yacoub technique with aortic annuloplasty from November 2017 to January 2019. There were 5 males and 1 female, with a mean age of 54.1±12.3 years. The preoperative cardiac function of 3 patients was in New York Heart Association (NYHA) classⅡand the other 3 patients were in class Ⅲ. There were two patients with bicuspid aortic valve, and no Marfan syndrome. There was aortic regurgitation in the patients measured by the echocardiogram, 1 in mild aortic regurgitation, 1 in moderate aortic regurgitation, and 4 in severe aortic regurgitation. The diameter of aortic annular base was 27.8±1.9 mm, and the largest diameter of aortic root was 49.8±3.7 mm. Six patients underwent modified Yacoub technique with aortic annuloplasty, including 5 patients who underwent aortic cusp repair at the same time. Results All 6 identified patients survived. There was no severe complication (bleeding, stroke, or acute renal failure). The cardiopulmonary bypass time was 204.6±13.5 min, aortic cross-clamping time 168.0±17.1 min, mechanical ventilation time 21.3±19.5 h, ICU stay time 67.8±62.2 h. The follow-up time ranged from 4 to 18 months with an average time of 12.8±4.7 months. Patients' cardiac function improved postoperatively with four patients in NYHA classⅠand two patients with classⅡ. Two patients had no aortic valve regurgitation, four patients had mild regurgitation. Left ventricular end diastolic volume decreased significantly (118.6±20.4 mL vs. 169.1±58.4 mL, P<0.05). Conclusion The modified Yacoub technique with aortic annuloplasty is effective and safe for the patients with aortic root aneurysm and dilatation of aortic annular base, and the early- and mid-term outcomes are satisfactory.
