Surgical management of unroofed coronary sinus syndrome: A 20-year-single-center experience

Multimodality Imaging in the Diagnosis of Unroofed Coronary Sinus in the Adult

•Unroofed CS is a rare cause of atrial-level shunting and right heart dilatation. •Unroofed CS is commonly diagnosed in adulthood. •TTE is the primary modality to recognize and diagnose unroofed CS. •CCT and/or magnetic resonance imaging should be done as complementary studies before CS repair.

Simultaneous Identification of Unroofed Coronary Sinus Atrial Septal Defect and Atrial Septal Defect Secundum Using Cardiac Computed Tomography Angiography

Unroofed coronary sinus (UCS) represents a rare subtype of atrial septal defect (ASD), an adult congenital heart disease characterized by communication between the systemic and pulmonary circulations at the atrial level. This case report presents the unique occurrence of a large, unrepaired ASD secundum and an incidentally identified UCS type II in a 25-year-old female during a cardiac murmur assessment. The diagnosis of ASD secundum was initially made using transthoracic echocardiography (TTE) and was later confirmed with a transesophageal echocardiogram. The identification of the UCS was achieved through the utilization of cardiac computed tomography angiography (CCTA). Ultimately, the patient underwent a successful reroofing procedure using a bovine pericardial patch.

Intracardiac baffle repair of complex completely unroofed coronary sinus with persistent left superior vena cava in an adult

A 35-year-old woman presented with dyspnea on exertion. The diagnosis was unroofed coronary sinus with persistent left superior vena cava and atrial septal defect. She underwent total correction with the intracardiac baffle technique by using an interatrial flap and autologous pericardial patch. Her clinical course was uneventful and markedly improved after the surgery.
