Key result
Surgical repair successfully resolved both severe mitral stenosis and severe mitral regurgitation in a 3.5-year-old boy with a rare combination of a supramitral ring and an anterior leaflet cleft.
Case Report (n=1)
This case report describes the first known coexistence of a supramitral ring and an isolated mitral valve cleft, which was successfully treated with surgical repair.
May inform individualized repair strategies for rare pediatric mitral anomalies; leaves open durability, prevalence, and generalizability.
A supramitral ring is a rare cause of mitral stenosis, while an isolated mitral valve cleft is a rare cause of congenital mitral regurgitation. Fortunately, both the lesions are known to have good outcomes after surgical correction. Although each is known to be associated with a variety of other structural heart defects, their coexistence has not been reported previously. We report a case of a three- and half-year-old boy detected to have a rare combination of supramitral ring producing severe mitral stenosis with a coexisting cleft in the anterior leaflet of mitral valve causing severe mitral regurgitation. The patient underwent successful surgical repair with resolution of both mitral stenosis and regurgitation.

Nair et al. (2018) conducted a case report in Mitral stenosis and mitral regurgitation (n=1). Surgical repair was evaluated on Resolution of mitral stenosis and regurgitation. Surgical repair successfully resolved both severe mitral stenosis and severe mitral regurgitation in a 3.5-year-old boy with a rare combination of a supramitral ring and an anterior leaflet cleft.
