Abstract:
The case is described of a pediatric patient with hypertrophic non-obstructive cardiomyopathy (HNCM) presenting with aortic and mitral regurgitation. This 17-year-old boy had been followed for HNCM since he was aged 4 years. Serial echocardiography had been showing the emergence and progression of aortic regurgitation and mitral regurgitation since the patient was aged 6 years. He started to have syncope attacks at 16 years of age and fell into congestive heart failure at 17 years. He underwent successful mitral valve repair by means of double-orifice technique, and aortic valve repair with raphe triangular resection, cusp plication and subvalvular annuloplasty.
