MITRAL VALVE PROLAPSE AND CONGENITAL PYLORIC STENOSIS IN IDENTICAL TWINS

Both congenital pyloric stenosis and the mitral valve prolapse syndrome are reported to have a familial incidence. Although mitral valve prolapse has been documented in twins, only one case has received echocardiographic confirmation. The present account describes typical symptomatic mitral valve prolapse in identical twins, both of whom had undergone surgery during infancy to correct congenital pyloric stenosis.
