Levoatriocardinal Vein With Multiple Ventricular Septal Defects and Without Left-Sided Valvular Atresia

Area of Science:

• Cardiovascular Medicine
• Congenital Heart Disease
• Medical Imaging

Background:

• The levoatrial cardinal vein (LACV) is a rare congenital anomaly, typically associated with left-sided heart obstructive lesions.
• Its isolated occurrence without left-sided valvular atresia is exceptionally uncommon.

Observation:

• This report presents a case of LACV in a patient with multiple muscular ventricular septal defects (VSDs).
• The patient also exhibited a small atrial septal defect (ASD) and mitral regurgitation (MR).

Findings:

• The imaging findings confirmed the presence of LACV coexisting with complex VSDs and ASD.
• The co-occurrence of LACV with these specific defects, particularly without left-sided atresia, is noteworthy.

Implications:

• This case expands the spectrum of known presentations for LACV.
• Accurate diagnosis through advanced imaging is crucial for understanding the associated hemodynamics and planning management.
• Further research into the embryological origins and clinical significance of isolated LACV is warranted.
