Cardiac Computed Tomography Angiography Unveils a Concurrent Unroofed Coronary Sinus Atrial Septal Defect with Atrial Septal Defect Secundum - Abstract
Unroofed coronary sinus is a rare subtype of atrial septal defect, which is an adult congenital heart disease characterized by communication of the systemic and pulmonary circulations at the atria level. We describe a 25-year-old female with a rare coexistence of a large unrepaired atrial septal defect secundum, and Unroofed coronary sinus type II identified incidentally during a cardiac murmur assessment. Atrial septal defect secundum was diagnosed with transthoracic echocardiography and was confirmed with transesophageal echocardiogram. Unroofed coronary sinus was diagnosed using cardiac computed tomography angiography. The patient underwent a successful reroofing using bovine pericardial patch.
