Surgical treatment of congenital mitral valve disease: Midterm results of a repair-oriented policy

Abstract

Objective: Management of congenital mitral valve disease is challenging because of a wide morphologic spectrum, frequent associated lesions, and small patient size. We evaluated the results of a repair-oriented policy. Methods: All consecutive patients with congenital mitral valve disease who underwent surgery between 1996 and 2006 were studied retrospectively. Patients with atrioventricular canal, atrioventricular discordance, or ischemic regurgitation were excluded. Results: During this period, 71 children (median age 2.9 years, range 3 days-20.8 years) underwent surgery. All but 1 underwent primary mitral valve repair. Twenty-two (30%) were younger than 12 months. Associated cardiac lesio..
