Insights
Echocardiography can predict patent ductus arteriosus (PDA) closure method. Pulmonary end diameter is a key predictor for device closure in PDA patients.
Area of Science:
- Cardiology
- Medical Imaging
- Pediatric Cardiology
Background:
- Patent ductus arteriosus (PDA) is a common congenital heart defect.
- Transcatheter closure is a primary treatment for PDA.
- Choosing between device and coil closure requires careful consideration of patient-specific factors.
Purpose of the Study:
- To identify echocardiographic predictors differentiating device versus coil closure for PDA.
- To establish criteria for optimal transcatheter closure selection.
Main Methods:
- Seventy-six patients undergoing elective transcatheter PDA closure were studied.
- Comprehensive echocardiograms measured PDA diameter, flow dynamics, and cardiac chamber dimensions.
- Patients were divided into coil (n=42) and device (n=34) closure groups.
Main Results:
- Pulmonary end diameter, color flow width, and extent significantly differed between groups (P < .0001).
- Device closure was associated with larger cardiac volumes and greater diastolic flow reversal.
- Pulmonary end diameter > 2.5mm (suprasternal) or > 2.61mm (parasternal) predicted device closure with high accuracy (AUC 0.971-0.979).
Conclusions:
- Echocardiographic variables, including pulmonary end diameter, can guide the choice between PDA coil and device closure.
- Pulmonary end diameter measured from the suprasternal view emerged as the most independent predictor for device closure.
Aim:
To determine anatomic and hemodynamic echocardiographic predictors for patent ductus arteriosus (PDA) device vs coil closure.
Methods:
Seventy-six patients who were referred for elective transcatheter PDA closure were enrolled in the study. All patients underwent full echocardiogram including measurement of the PDA pulmonary end diameter, color flow width and extent, peak and end-diastolic Doppler gradients across the duct, diastolic flow reversal, left atrial dimensions and volume, left ventricular sphericity index, and volumes.
Results:
The study group was subdivided into 2 subgroups based on the mode of PDA closure whether by coil (n = 42) or device (n = 34). Using univariate analysis there was a highly significant difference between the 2 groups as regard the pulmonary end diameter measured in both the suprasternal and parasternal short-axis views as well as the color flow width and color flow extent (P < .0001). The device closure group had statistically significant higher end-systolic and end-diastolic volumes indexed, left atrial volume, and diastolic flow reversal. Receiver operating characteristic curve analysis showed a pulmonary end diameter cutoff point from the suprasternal view > 2.5 mm and from parasternal short-axis view > 2.61 mm to have the highest balanced sensitivity and specificity to predict the likelihood for device closure (AUC 0.971 and 0.979 respectively). The pulmonary end diameter measured from the suprasternal view was the most independent predictor of device closure.
Conclusion:
The selection between PDA coil or device closure can be done on the basis of multiple anatomic and hemodynamic echocardiographic variables.
