Surgical correction for sinus of valsalva aneurysm with right ventricular outflow tract stenosis

Sinus of Valsalva aneurysm (SVA) is a rare cardiac anomaly, and SVA combined with right ventricular outflow tract stenosis is even rarer. We retrospectively analyzed 222 patients receiving surgical repair of SVA in our center over nine years, and report the incidence of right ventricular outflow tract stenosis in SVAs and the surgical results of 13 cases of SVA with right ventricular outflow tract stenosis.

Between January 2000 and December 2009, 13 patients with SVA combined with right ventricular outflow tract stenosis underwent surgical repair of SVA and correction of right ventricular outflow tract stenosis. There were nine males and four females. The mean age was 29.69 ± 9.98 years (range 13 to 45 years). Associated cardiovascular lesions were ventricular septal defect (n = 12), aortic regurgitation (n = 9), mitral regurgitation (n = 2), and tricuspid regurgitation (n = 1). All 13 patients were followed from 35 to 126 months (mean 80.15 ± 32,14 months).

There was neither early death after operation nor late death. All the patients recovered well uneventfully. The incidence of right ventricular outflow tract stenosis among 222 SVA patients was 5.86%.

Surgical correction of SVA with right ventricular outflow tract stenosis results in good mid-term results. Longer follow-up is needed to determine the efficacy of this procedure as this cohort of patients ages.
