Ventricular inversion associated with normally related great vessels

Area of Science:

• Cardiology
• Pediatric Cardiology
• Medical Genetics

Background:

• Ventricular inversion with normally related great vessels is a rare congenital heart defect.
• Double inlet left ventricle is a complex cardiac anomaly where both atria connect to a dominant left ventricle.
• Down's syndrome (Trisomy 21) is a genetic disorder associated with an increased risk of congenital heart defects.

Observation:

• A patient presenting with ventricular inversion, normally related great vessels, and a double inlet left ventricle was identified.
• The patient also exhibited phenotypic features consistent with Down's syndrome.
• This combination of cardiac malformations and genetic syndrome is exceptionally uncommon.

Findings:

• The anatomical arrangement results in a functional state mimicking complete transposition of the great vessels.
• The specific connections between the ventricles and great vessels dictate the altered hemodynamics.
• The co-occurrence of this rare cardiac anomaly with Down's syndrome is a significant clinical observation.

Implications:

• Highlights the importance of comprehensive cardiac evaluation in patients with Down's syndrome.
• Contributes to the understanding of rare congenital heart disease associations.
• Informs clinical management strategies for complex cyanotic heart disease in syndromic patients.
