title: Complete A-V block: incidental or a part of cor triatriatum dexter.
abstract: Cor triatriatum dexter (CTD) is an extremely rare cardiac anomaly in which the right atrium is divided into two distinct chambers by a membrane. The persistence of the right valve of sinus venosus results in a complete septation of the right atrium. This anomaly is frequently associated with other right-sided cardiac abnormalities. Its clinical manifestation and the need for intervention are determined by the number and the size of the fenestrations on the membrane, associated cardiac anomalies and arrhythmias. We describe a case of CTD in a patient with complete atrioventricular (A-V) block.
