Rare Case of Unileaflet Mitral Valve

Unileaflet mitral valve is the rarest of the congenital mitral valve anomalies and is usually life threatening in infancy due to severe mitral regurgitation (MR). In most asymptomatic individuals, it is mostly due to hypoplastic posterior mitral leaflet. We present a 22-year-old male with palpitations, who was found to have an echocardiogram revealing an elongated anterior mitral valve leaflet with severely hypoplastic posterior mitral valve leaflet appearing as a unileaflet mitral valve without MR. Our case is one of the 11 reported cases in the literature so far. We hereby review those cases and conclude that these patients are likely to be at risk of developing worsening MR later in their lives.

Mitral Insufficiency due to Isolated Cleft Mitral Valve in Anterior Mitral Leaflet: A case report / 대한흉부외과학회지

A 45 year-old man who suffered with palpitation and dyspnea for 3 years visited our hospital. He was dianosed as mitral insufficieny due to isolated cleft mitral valve in anterior mitral leaflet on the basis of transthoracic echocardiogram In our case edges of the cleft were relatively thin and smooth. The entire length of the cleft was sutured with 5-0 Prolene(R) interrupted sutures. We report a case of direct suture repair in a patient with isolated cleft in anterior mitral valve leaflet.
