Abstract:
A 26-year-old woman presented with palpitations and exertional dyspnea. Echocardiography suggested an inferior sinus venosus atrial septal defect, while cardiac CT angiography revealed a 26 × 32 mm defect with inferior vena cava overriding, a persistent left superior vena cava draining into the left atrium, and a coronary sinus with an intact roof draining independently into the left atrium. Surgical correction involved patch closure of the atrial septal defect and redirection of both venous structures to the right atrium. Postoperative imaging demonstrated no residual interatrial shunt and confirmed patency of the redirected persistent left superior vena cava. This case highlights the essential role of multimodality imaging in defining complex congenital venous anatomy and guiding surgical management .

Overview of Systemic Veins
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the middle...

Coronary Circulation
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...

Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
