Ross‐Kabbani Operation in an Infant with Mitral Valve Dysplasia

Abstract

Background . Mitral valve replacement can be very difficult to obtain in infants because the valve annulus diameter can be smaller than the available prosthesis. Case Report . We describe the case of a 2‐month‐old female weighing 3.5 kg affected by mitral valve dysplasia leading to severe valve stenosis. Despite full medication, the clinical conditions were critical and surgery was undertaken. The mitral valve was unsuitable for repair and the orifice of mitral anulus was 12 mm, too small for a mechanical prosthesis. Therefore, a Ross‐Kabbani operation was undertaken, replacing the mitral valve with the pulmonary autograft and reconstructing the right ventricular outflow tract with an etherograft. Results . The postoperative course was uneventful and the clinical conditions are good at 4‐month follow‐up. Conclusion . The Ross‐Kabbani operation can be an interesting alternative to mitral valve replacement in infants when valve repair is not achievable and there is little space for an intra‐annular mechanical prosthesis implant.
