|May 1, 1991
Summary
Colour flow mapping (CFM) effectively diagnoses congenital ventricular septal defects (VSD) and confirms closure. CFM improves detection rates, especially for muscular VSD, and assesses spontaneous or surgical closure in pediatric patients.
Area of Science:
- Pediatric Cardiology
- Diagnostic Imaging
- Echocardiography
Background:
- Congenital ventricular septal defects (VSD) are common heart abnormalities.
- Accurate diagnosis and monitoring of VSD closure are crucial for patient management.
Purpose of the Study:
- To evaluate the utility of colour flow mapping (CFM) in diagnosing and classifying congenital VSD.
- To assess CFM's role in confirming spontaneous and surgical VSD closure.
- To determine CFM's effectiveness in evaluating hemodynamics and flow in pediatric VSD patients.
Main Methods:
- 102 pediatric patients with isolated VSD underwent 176 echocardiographic examinations.
- Assessment utilized sequential cross-sectional imaging and CFM with Doppler interrogation.
- Patients were categorized into preoperative (n=82) and postoperative (n=20) groups.
Main Results:
- CFM detected VSD in 88.9% of muscular, 57.6% of doubly committed subarterial, and 11.8% of perimembranous types.
- Spontaneous closure rates were higher in muscular (28.6%) and perimembranous (8.9%) VSD.
- CFM rapidly confirmed complete surgical closure in all 20 postoperative patients.
Conclusions:
- CFM is a valuable tool for diagnosing and classifying congenital VSD in children.
- CFM aids in assessing spontaneous and surgical closure, as well as hemodynamic status.
- CFM enhances cross-sectional imaging for comprehensive VSD evaluation.
