Criss-cross heart with straddling right atrioventricular valve
Clinical Cardiology
|September 1, 1984
Summary
This case study presents a rare criss-cross heart anomaly with straddling tricuspid valve. Combined imaging techniques like angiography and echocardiography are crucial for diagnosing complex congenital heart defects.
Area of Science:
- Cardiology
- Pediatric Cardiology
- Congenital Heart Disease
Background:
- Criss-cross heart, a rare congenital anomaly, involves abnormal spatial arrangement of ventricles.
- Straddling tricuspid valve is a complex defect where the valve annulus is displaced over the ventricular septum.
Observation:
- A case of criss-cross heart with normal atrial situs and a straddling tricuspid valve was analyzed.
- The morphological right ventricle was superior and left, connected to the right atrium, while the left ventricle was inferior and right, connected to the left atrium.
- Both great arteries originated from the right ventricle, with the aorta anteriorly positioned.
Findings:
- The condition was diagnosed as criss-cross heart with a concordant atrioventricular (A-V) connection and double outlet right ventricle (DORV).
- Two-dimensional (2-D) echocardiography initially identified the straddling right A-V valve, which was confirmed by right atrial angiography.
Implications:
- This highlights the importance of advanced imaging in diagnosing complex cardiac malformations.
- Integrated diagnostic approaches using echocardiography and angiography are vital for accurate characterization and management of such anomalies.
