Common atrium, a rare congenital malformation, has many similarities with the more usual atrioventricular septal defect limited to the lowermost portion of the atrial septum: a left-toright shunt; an identical type of common atrioventricular valve that may have only one orifice (5) but usually has right and left orifices (3, 5, 6), either or both of which may be incompetent; and a rather characteristic electrocardiogram showing right ventricular enlargement, left anterior fascicular block and, in 50% of patients, a long P-R interval (7, 8).
In several respects, however, common atrium differs from atrioventricular septal defect limited to the lowermost portion of the atrial septum.
