Abstract

BACKGROUND:

Sinus of Valsalva aneurysm (SVA) is a rare cardiac anomaly, and SVA with discrete membranous subaortic stenosis is even rarer. The aim of the study was to make sure the incidence of SVA with discrete membraneous subaortic stenosis in SVA and their surgical results. We retrospectively analyzed 234 patients receiving surgical repair of SVA and reported the incidence of ventricular septal defect, aortic regurgitation, and discrete membranous subaortic stenosis. We also reported seven cases of SVA combined with discrete membranous subaortic stenosis and their surgical results.

METHODS:

Between January 1999 and December 2009, seven patients of SVA with discrete membranous subaortic stenosis underwent surgical repair of SVA and resection of subaortic discrete membrane. There were six male and one female patients. The mean age was (33.71 ± 13.25) years (range 16 - 52 years). Associated cardiovascular lesions were aortic regurgitation (n = 7), ventricular septal defect (n = 5), coarctation of aorta (n = 1), bicuspid aortic valve (n = 1), patent ductus arteriosus (n = 1), and aortic valve stenosis (n = 1). The aortic valve was replaced in four patients and valvuloplasty was done in three. The other co-existing anomalies were corrected at the same time. All the seven patients were followed up from 18 to 125 months (mean (63.14 ± 39.54) months). Among 234 SVA patients who underwent surgical repair, the number of cases with coexisting ventricular septal defect, aortic regurgitation, and discrete membranous subaortic stenosis was 129, 108, and 7, respectively.

RESULTS:

There was neither early death after operation nor late death during the follow-up period. All the seven patients were in the New York Heart Association (NYHA) functional classes I and II. There was no recurrence of discrete subaortic membrane during the follow-up period. The incidence of ventricular septal defect, aortic valve incompetence, and discrete membranous subaortic stenosis among 234 SVA patients was 55.13%, 46.15%, and 2.99%, respectively.

CONCLUSIONS:

Surgical repair of SVA with discrete membranous subaortic stenosis showed good mid-term results. Resection of discrete subaortic membrane should be done actively while repairing SVAs. Long-term results need to be followed up.
