title: Real-time three-dimensional echocardiography in assessment of congenital double orifice mitral valve.
abstract: The application of real-time three-dimensional echocardiography (RT 3DE) in the diagnosis of double orifice mitral valve (DOMV) was explored. Five cases of DOMV were examined by using 2-dimensional echocardiography (2DE) and RT 3DE. The spatial morphology of malformed mitral valve and its change in hemodynamics were observed. DOMV associated with partial atrioventricular septal defect was found in 3 cases (in which 2 cases had cleft mitral valve) and isolated DOMV in 2 cases; and moderate to severe mitral regurgitation was detected in 3 cases, and mild mitral regurgitation in 1, and no regurgitation in 1 case; 1 case had complicated rhumatic heart disease. Three cases were preoperatively discovered by 2DE, while 2 missed (1 case was discovered postoperatively). Four cases were diagnosed by RT 3DE preoperatively, and 1 case was diagnosed postoperatively (not examined by RT 3DE preoperatively). It was suggested that RT 3DE is a reliable technique in the diagnosis of DOMV; it permitted comprehensive and noninvasive assessment of mitral valve and may supplement 2D TTE in the assessment of DOMV.
