title: Ventricular pseudoaneurysm after transaortic septal myotomy for hypertrophic subaortic stenosis.
abstract: Clinical and morphological features are described in a man in whom a pseudoaneurysm arising from the ventricular septum developed after transaortic septotomy for hypertrophic subaortic stenosis. Pseudoaneurysm of the left ventricle or ventricular septum has not been described previously in a patient with hypertrophic cardiomyopathy in whom only the transaortic approach was utilized for septotomy or septectomy or both. In addition, no previous studies have reported pseudoaneurysm arising from the ventricular septum.
