Abstract
Three cases of congenital cardiac anomalies involving the Eustachian valve are presented. The first is a case of a 12-year-old boy with findings of severe chronic myocarditis combined with an anomalous Eustachian valve which divided the right atrium and caused moderate constriction of the inferior veana cava orifice, resulting in marked congestion of the intraabdominal viscera. The second case, a 30-day-old male infant, exhibited an area of aneurysmal dilatation in the midportion of the Eustachian valve associated with interventricular septal defect and right aortic arch. The third case, a 9-month-old male child with interventricular septal defect, transposition of the great vessels, bicuspid pulmonic valve and anomalous origin of the left subclavian artery, had an abnomrally enlarged, membranous Eustachian valve. A review of similar anomalies reported in the literature and of the classification of minor variations and major anomalies is presented.
