Not Just a Double Orifice Mitral: A case Report of a Heart with Two distinct Mitral Valves, Silent for 35 Years

Abstract Introduction:Double mitral valve is a rare congenital malformation, in which two anatomically distinct mitral valves exist. it most commonly diagnosed in infancy or childhood and frequently associated with other structural cardiac anomalies. Due to its rarity, epidemiological data are lacking.Case Presentation:We present the case of a 35-year-old asymptomatic male in whom a true duplicated mitral valve was incidentally discovered during a routine echocardiographic evaluation. Transthoracic echocardiography in multiple views-including two-chamber and four-chamber apical views-revealed two completely separate mitral valves, each with its own set of leaflets and orifice. Color Doppler imaging confirmed normal flow through both valves without regurgitation or stenosis. No associated congenital cardiac anomalies were identified. Follow-up with periodic echocardiography was planned for the patient.Conclusion:This case highlights double mitral valve, presenting in an adult with no symptoms and no associated defects. Early and accurate diagnosis, even in asymptomatic individuals, is essential to guide long-term follow-up and prevent potential future complications.
