Abstract

Background:Aortic root aneurysms combined with lesions of the mitral valve requires synchronous operations. The conventional approach is to treat the two lesions through separate aortic and atrial incisions.Methods:From May 2009 to August 2012, 28 transaortic mitral valve operations were performed. There were 23 males and five females, the age ranged from 18 to 75 years, mean 41 ± 16 years. The operative procedures included Bentall + MVR in 20 patients, Bentall + MVP in three patients, Bentall + total arch replacement + stent elephant trunk + MVP in one patient, Bentall + total arch replacement + stent elephant trunk + MVR in two patients, Bentall + MVP + CABG in two patients. Follow-up was completed for all patients, with a mean follow-up period of 22 ± 10 months and a maximum of 42 months.Results:Transaortic mitral valve surgery was successful for all patients. There was a reoperation in two patients for bleeding. In the MVP group, there was mild regurgitation in two cases before discharge, without further development during the follow-up. In the MVR group, there was paravalvular leakage in one patient three months later, which required repair. There were no deaths in the hospital and the follow-up period, and no valve-associated complication during the follow-up period. The heart function of all patients during the follow-up period was Level I–II (NYHA).Conclusion:Transaortic mitral valve operation is a feasible surgical approach to treat patients with aortic root aneurysms combined with mitral valve lesions.
