Straddling atrioventricular valve: two-dimensional echocardiographic diagnosis, classification and surgical
The American Journal of Cardiology
|February 15, 1985
Summary
Two-dimensional echocardiography accurately identifies straddling atrioventricular (AV) valves, classifying straddling types (A, B, C) and overriding severity. This classification impacts surgical planning and outcomes in complex congenital heart disease.
Area of Science:
- Cardiology
- Medical Imaging
- Pediatric Cardiology
Background:
- Straddling and overriding atrioventricular (AV) valves are complex congenital heart anomalies.
- Accurate anatomical subclassification is crucial for surgical management and predicting outcomes.
Purpose of the Study:
- To evaluate the utility of 2-dimensional echocardiography in subclassifying anatomical variations of straddling and overriding AV valves.
- To correlate echocardiographic findings with surgical or autopsy data.
Main Methods:
- Retrospective analysis of 52 patients with straddling AV valves diagnosed via echocardiography.
- Classification of straddling chordae into types A, B, and C.
- Categorization of overriding AV valve annulus as minor, major, or double-inlet ventricle.
Main Results:
- 2-D echocardiography correctly identified the diagnosis and straddling type in 91% of 66 straddling AV valves.
- Associated defects included double-outlet right ventricle, transposition of the great arteries, and double-inlet ventricle.
- Straddling AV valves significantly impacted surgical type or outcome in 41% of patients, with type C (severe) being most common.
Conclusions:
- 2-D echocardiography is a valuable tool for subclassifying straddling and overriding AV valves.
- Detailed echocardiographic assessment aids in surgical planning and improves outcomes for patients with these complex cardiac anomalies.
