Aortic and mitral discontinuity with congenital subaortic aneurysm and normally connected great arteries: echocardiographic diagnosis in life.
A newborn with preductal coarctation and ventricular septal defect had a subaortic aneurysm which protruded into the left atrium causing intractable pulmonary oedema. The subaortic aneurysm was congenital. It was clearly identified by cross-sectional echocardiography which, in serial studies, showed it to be increasing in size. Predisposing to its development was the wide area of aortic and mitral discontinuity in association with the concordant ventricular connexion of the great arteries. The child remained in worsening pulmonary oedema after relief of the coarctation and banding of the pulmonary trunk and died after attempted relief of the left atrial obstruction.
