Two unusual congenital anomalies of the tricuspid valve.
We describe two unusual congenital anomalies of the tricuspid valve discovered incidentally at autopsy. One is an abnormal attachment of the tricuspid septal leaflet to one of two posterior papillary muscles with a concomitant fusion of the right ventricular septal and anterior papillary muscles in a patient with ectodermal dysplasia. The other involves a fenestration defect of the septal leaflet of the tricuspid valve in a patient with aortic stenosis, coronary artery atherosclerosis, and cardiac amyloidosis.
