Coronary sinus draining into the left subclavian vein through a persistent left superior vena cava.

چکیده
A persistent left superior vena cava (PLSVC) is formed by the remains of the oblique vein of the left atrium, which is not completely degenerated during embryonic development. The incidence is approximately 0.3% in the general population. Approximately 80-92% of PLSVCs drain into the right atrium through the coronary sinus. This report describes a rare case of PLSVC in which the coronary sinus (CS) did not open into the right atrium, but rather drained into the left subclavian vein through the PLSVC.

A 3-week-old female underwent transthoracic echocardiography (iE33, Philips medical system, Andover, MA, USA) to evaluate a grade 1 systolic murmur. In the subcostal view, blood flow in the inferior vena cava drained to the right atrium, while no blood flow from the superior vena cava to the right atrium was noted (Figure 1A). In the four-chamber view, no superior vena caval blood flow was seen...

Anomalous vena cavae can have significant implications for procedures on the right side of the heart. We report a rare anatomical configuration in a 44-year-old female, which to the best of our knowledge, is the first report of such an association. She had a bicuspid aortic valve in conjunction with a persistent left superior vena cava (PLSVC) draining into the coronary sinus, and a left-sided ...
متن کاملPersistent Left Superior Vena Cava Draining into the Coronary Sinus: A Case Report
Persistent left superior vena cava (PLSVC) is a congenital anomaly of the thoracic venous system resulting from the abnormal persistence of an embryological vessel that normally regresses during early fetal life. This anomaly is often discovered incidentally during surgery, cardiovascular imaging or invasive cardiovascular procedures. In most cases, a PLSVC drains into the right atrium through ...
