Atrial septal defects (ASDs) make up about 10%-15% of congenital heart diseases. Clinical sequelae are insidious and present around the fourth decade of life. Arrhythmias such as atrial fibrillation and atrial flutter are common in patients with delayed presentation, while conduction abnormalities are rare. Conduction abnormalities mainly occur after defect closure by surgery or percutaneous device. Hereditary forms of ASD, as seen in the Holt-Oram syndrome, may also be associated with conduction disturbances. Our case is a female with newly diagnosed ostium primum ASD in the sixth decade of life and with the unusual presentation of atrial fibrillation coexisting with a complete atrioventricular block. We highlight the need for genetic testing in this uncommon clinical scenario.
