Unroofed coronary sinus and persistent left superior vena cava: A case report

Area of Science:

• Cardiology
• Radiology
• Medical Imaging

Background:

• Unroofed coronary sinus is a spectrum of cardiac anomalies characterized by partial or complete absence of the interatrial wall separating the coronary sinus from the left atrium.
• These anomalies frequently coexist with anomalous systemic venous return, notably persistent left superior vena cava.
• Diagnosis can be challenging due to nonspecific clinical presentations, impacting patient prognosis.

Purpose of the Study:

• To report a case of a complete unroofed coronary sinus and persistent left superior vena cava.
• To illustrate the utility of computed tomography in diagnosing this rare cardiac anomaly in the context of pulmonary hypertension.

Main Methods:

• Computed tomography (CT) investigation was performed.
• The diagnostic process involved detailed imaging analysis to identify cardiac anomalies.

Main Results:

• A complete unroofed coronary sinus was identified.
• A persistent left superior vena cava was also diagnosed.
• These findings were discovered during a CT scan for pulmonary hypertension.

Conclusions:

• The case demonstrates the successful diagnosis of a complete unroofed coronary sinus and persistent left superior vena cava using computed tomography.
• This highlights the importance of advanced imaging in diagnosing rare cardiac anomalies, especially when presenting with conditions like pulmonary hypertension.
