Insights
This study details a rare congenital heart defect with parallel great arteries, a divided left atrium, and other complex anomalies. Understanding these morphological features is crucial for diagnosis and management.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Medical Morphology
Background:
- Congenital heart defects represent a significant burden in pediatric cardiology.
- Complex cardiac anomalies require precise morphological description for accurate diagnosis.
Purpose of the Study:
- To describe the detailed morphological features of a rare case of concordant ventriculoarterial connections with associated anomalies.
- To highlight the diagnostic challenges posed by this complex cardiac malformation.
Main Methods:
- Detailed morphological examination of the cardiac specimen.
- Review of clinical presentation and diagnostic imaging.
Main Results:
- The patient presented with concordant ventriculoarterial connections and parallel arterial trunks.
- Additional findings included cor triatriatum sinister, ventricular septal defect, bilateral superior caval veins, and juxtaposed atrial appendages.
- The aorta was noted to be anterior and left-sided.
Conclusions:
- This case underscores the variability and complexity of congenital heart disease.
- Accurate morphological assessment is essential for diagnosing and managing rare cardiac anomalies.
Abstract:
We describe a patient with concordant ventriculoarterial connections with parallel arterial trunks, divided left atrium (cor triatriatum sinister), ventricular septal defect, bilateral superior caval veins, and juxtaposed atrial appendages. The aorta was anterior and left sided. We discuss the morphological features of this rare condition, and the diagnostic dilemma it produced.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
