Abstract
OBJECTIVE
Transcatheter closure is the first-choice strategy for the management of appropriate patients with patent ductus arteriosus (PDA). The management of large PDAs is challenging due to the limited available sizes of approved devices and the inherent risks of surgical ligation, especially in adults with calcified PDAs. This study aimed to assess the outcomes of the off-label use of large occluders at a tertiary center.
METHODS
This retrospective review included patients who underwent transcatheter PDA closure with large occluders (≥16 mm) over 16 years. The baseline patient data, procedural details, angiograms, and immediate outcomes were recorded and patients were followed up at 3, 6, 12 months after the intervention and annually thereafter.
RESULTS
Of the 685 patients who underwent transcatheter PDA closure, 36 patients (mean age 16.6 ± 12.5 years) needed occluders ≥ 16 mm in size. Cocoon duct occluder, Cera duct occluder, Amplatzer atrial septal occluder (ASO), and Cera muscular ventricular septal defect occluders were used for PDA closure. There was no device embolization, one patient in whom ASO was used had residual shunt with intravascular hemolysis requiring surgery, and one patient had mild left pulmonary artery narrowing after the intervention, which was managed conservatively. No patient had residual shunt and one patient had persistent pulmonary hypertension at an intermediate duration of follow-up.
CONCLUSION
Transcatheter PDA closure with the use of large devices, which are available in Asia and Europe, is an effective and safe method, especially in adolescents and adults. However, a close follow-up of these patients is mandatory.
