Persistent left superior vena cava, absence of the innominate vein, and upper sinus venosus defect : a rare anomaly...

Area of Science:

• Cardiology
• Thoracic Surgery
• Medical Imaging

Background:

• Congenital heart defects frequently involve superior vena cava anomalies.
• Persistent left superior vena cava is the most common thoracic venous anomaly.
• Combinations of specific superior vena cava anomalies with other cardiac defects are exceptionally rare.

Observation:

• A patient presented with a rare combination of congenital anomalies.
• The anomalies included a persistent left superior vena cava, an upper sinus venosus defect, and absence of the innominate vein.
• Diagnostic procedures involved a bubble study and magnetic resonance imaging.

Findings:

• The study confirms an extremely rare coexistence of persistent left superior vena cava, upper sinus venosus defect, and absent innominate vein.
• Diagnostic imaging successfully identified these complex thoracic venous anomalies.
• This case highlights the utility of bubble studies and MRI in diagnosing rare cardiac malformations.

Implications:

• Accurate diagnosis of rare venous anomalies is crucial for appropriate patient management.
• This case expands the understanding of the spectrum of superior vena cava malformations.
• Advanced imaging techniques are vital for characterizing complex congenital cardiac defects.
