All reports dealing with atresia of the tricuspid orifice state that it is an extremely rare anomaly. Breslich,1 reporting one of the most recent cases, reviewed the literature and stated that altogether there had been thirteen cases reported. We have noted that he did not include the case of Cathala and Tisserand2 reported in 1926. It may be that he did not consider that this was a true case of atresia, as they described a communication between the right auricle and the right ventricle by a narrow slit (bordered by muscular folds), without the presence of the usual interventricular defect. We recently saw a case which came to autopsy, and which we now wish to report.
