Objective
This study investigated the mid-term outcomes of simultaneous mitral valve repair in patients with mitral regurgitation (MR) and concomitant annulo-aortic ectasia.
Methods
The study included 26 patients with MR and annulo-aortic ectasia [mean age 46.0 ± 19.9 (10–86) years] who underwent simultaneous mitral valve repair between January 2007 and March 2018. Of these 26 patients, 11 (42.3%) were diagnosed with Marfan syndrome and 10 (38.5%) with Barlow’s disease. All patients underwent complete ring annuloplasty; a semi-rigid ring was used in 14 (53.8%) and a semi-flexible ring (anterior-flexible) in 12 patients (46.2%). All patients underwent valve-sparing root replacement using the reimplantation technique.
Results
The overall 3-year survival rate was 95.7 ± 4.3%. The 3-year freedom from > moderate MR rate was 94.7 ± 5.1%, and the 3-year freedom from > moderate aortic regurgitation (AR) rate was 86.7 ± 7.3%. The 3-year freedom from reoperation rate was 100%. The 3-year freedom from > moderate MR rate was 100% in the semi-rigid ring group and 85.7 ± 13.2% in the semi-flexible ring group (log-rank test, p = 0.5371). The 3-year freedom from > moderate AR rate was 100% in the semi-rigid ring group and 72.9 ± 16.5% in the semi-flexible ring group (log-rank test, p = 0.0815).
Conclusions
Simultaneous mitral valve repair in patients with MR and concomitant annulo-aortic ectasia showed favorable mid-term outcomes.
