Anomalous attachment of mitral valve causing subaortic atresia. Observations in a case with other cardiac anomalies and multiple spleens.

was hypertrophied. The case illustrates the most severe degree of subaortic obstruction that may result from anomalous attachment of the mitral valve to the ventricular septum. Also present vere multiple spleens, and other cardiovascular anomalies. The last included junction of a persistent left superior vena cava with the left atrium, absence of the coronary sinus, absence of the limbi of the fossa ovalis, and an anomnalous connection of the right pulmonary veins to the right atrium.
