Abstract:
The case of a 2-year-old infant admitted to our Institution with a diagnosis of severe aortic valve stenosis is presented. After a balloon valvuloplasty with no results in terms of gradient reduction, an echocardiogram showed a moderate mitral regurgitation. The patient underwent surgical repair of both the aortic and mitral valves. Inspection of the mitral valve showed a 5-mm hole in the posterior leaflet at the P2 scallop. Probably, the dilation tore a secondary cord, pulling away a piece of the leaflet. A quadrangular resection was performed with good results.
