A rare congenital anomaly, the absence of the right superior vena cava alongside a persistent left superior vena cava, was identified in a patient with atrial fibrillation. This case highlights the importance of diagnosing venous anomalies.

Area of Science:

  • Cardiology
  • Anatomy
  • Medical Imaging

Background:

  • Congenital venous anomalies, such as persistent left superior vena cava (PLSVC), are relatively common.
  • The simultaneous complete absence of the right superior vena cava (RSVC) is a rare occurrence.

Observation:

  • A patient presented with atrial fibrillation and a dilated coronary sinus.
  • Diagnostic imaging revealed a persistent left superior vena cava.
  • Contrast injection and phlebography confirmed the absence of the right superior vena cava.

Findings:

  • The primary finding was the rare co-occurrence of PLSVC and complete RSVC absence.
  • No other cardiac anomalies were identified in the patient.
  • The dilated coronary sinus was a consequence of the venous anomaly.

Implications:

  • This case underscores the diagnostic importance of recognizing rare venous anomalies.
  • Understanding the embryology and presentation of such anomalies is crucial for clinical practice.
  • Accurate diagnosis can prevent misinterpretation of imaging findings and guide patient management.
