Persistent Left Superior Vena Cava Draining Directly Into the Left Atrium With Occluded Coronary Sinus

Area of Science:

• Cardiology
• Medical Imaging
• Congenital Heart Disease

Background:

• Persistent left superior vena cava (PLSVC) is a rare congenital anomaly.
• An atretic coronary sinus (CS) is also uncommon.
• The combined occurrence of PLSVC entering the left atrium and an atretic CS is exceptionally rare.

Purpose of the Study:

• To describe a rare case of combined persistent left superior vena cava entering the left atrium with a congenitally atretic coronary sinus.
• To emphasize the importance of detailed cardiac vasculature assessment before interventional procedures.

Main Methods:

• Review of imaging findings.
• Anatomical correlation.

Main Results:

• Identification of a combined persistent left superior vena cava entering the left atrium and a congenitally atretic coronary sinus.
• The anomaly was asymptomatic in the absence of a significant right-to-left shunt.

Conclusions:

• This rare cardiac anomaly is typically asymptomatic and may be an incidental finding.
• Thorough pre-procedural assessment of cardiac vasculature is essential for patient safety.
