Trans-Catheter Closure of Patent Ductus Arteriosus, which device should we use?
Insights
Device selection for transcatheter closure of Patent Ductus Arteriosus (PDA) is crucial. Factors like patient age, weight, and duct anatomy significantly influence procedural success and complication risk.
Area of Science:
- Cardiology
- Pediatric Cardiology
- Interventional Cardiology
Background:
- Percutaneous closure of Patent Ductus Arteriosus (PDA) is a common procedure.
- Complications can occur during PDA closure, necessitating careful device selection.
Purpose of the Study:
- To review the experience with transcatheter device closure of PDA.
- To identify factors influencing the choice of closure device.
Main Methods:
- Retrospective analysis of patients undergoing transcatheter PDA closure between September 2003 and June 2016.
- Inclusion of 153 patients with PDA.
Main Results:
- Transcatheter closure was successful in 140 patients.
- Complications occurred in 11 patients, including device embolization and protrusion.
- Predictive factors for complications included age < 2 years, tubular PDA type C, and a high duct diameter/weight ratio.
- A mild residual shunt was observed in 22.85% of patients, with increased risk in younger patients, large PDAs, and those with pulmonary hypertension.
Conclusions:
- Device selection for PDA closure should be tailored to individual patient factors.
- Key determinants for device choice include patient age, weight, and specific ductal anatomy.
Abstract:
Despite the operational experience in the percutaneous closure of Patent ductus arteriosus (PDA), complications can arise during the procedure. To overcome these complications the choice of the device must be adapted to each patient.
Aim:
To report the experience of the cardiology department in the transcatheter device closure of PDA and to determine the influencing factors of choice of the device.
Methods:
Our study included patients with patent ductus arteriosus that are admitted for transcatheter closure, between September 2003 and June 2016.
Result:
One hundred and fifty-three patients were included in our study. Transcatheter closure was not done in 9 cases. The transcatheter closure was successful in 140 patients. The complications were observed in 11 patients that includes device embolization in 3 cases, aortic protrusion in four cases pulmonary protrusion in three cases and inguinal hematoma in one another. Three predictive factors of complications were: age < 2 years, tubular PDA type C and ratio duct diameter/weight > 0.95. A mild residual shunt was observed at the end of the procedure in 22.85 % of the patients. The risk of residual shunt was significantly increased when the age < 2 years, the large PDA, the presence of pulmonary hypertension and the tubular C PDA.
Conclusion:
The choice of the device depends essentially on age, the weight and the duct anatomy.
