Abstract:
Congenial mitral stenosis may be defined as a develpment abnormality of the mitral valve leaflets,commissures, interchordal spaces, papillary muscle,s annulus or immediate supravalvular area producing obstructionto left ventricular filling. Authors had experience of nine cases of congenital mitral stenosis confirmed by twodimenstional echocardiography, angiocardiography and surgery in recent 5 years since 1979, and analyzed them withemphasis on the angiographic findings. The results are as follows; 1. Among 9 cases, 6 patients were male and 3 were female. Age distribution was from 4 months to 11 years. 2. The types of congenital mitral stenosis were 1typical congenital mitral stenosis, 5 cases of parachute mitral valve and 3 cases of supramitral ring. 3. Angiographically typical congenital mitral stenosis showed narrowing of mitral valvular opening, parachute mitralvalve displayed single large papillary muscle with narrowed valvular opening and supramitral ring disclosedsemilunar shaped filling defect between left atrium and ventricle. 4. Associated cardiac and extracardiacanomalies of congenital mitral stenosis, as frequency wise, were ventricular septal defect, patent ductusarteriosus, coarctation of aorta, supra and subvalvular aortic stenosis, mitral regurgitation and double outletright ventricle. 5. Cardiac angiography is essential to diagnose congenital mitral stenosis, but the need of two dimensional echocardiography cannot be ignored.
