Transcatheter closure of patent ductus arteriosus in Chinese adults: immediate and long-term results.
BACKGROUND
Transcatheter closure of patent ductus arteriosus (PDA) has been established as a safe and effective treatment for pediatric patients. However, long-term experience in adults remains limited. Therefore, our purpose is to report our experience with this approach in Chinese adults.


METHODS
Twenty-five patients (mean age, 34 years) who underwent transcatheter closure of PDA in a tertiary cardiology center in Hong Kong were recruited.


RESULTS
The mean PDA diameter measured by angiogram was 3.1 mm (range, 1.3 6.6 mm) and the mean pulmonary-to-systemic shunt was 1.65 (range, 1.3 1.8). All procedures were performed under local anesthesia. The average procedure and fluoroscopy times were 54   14 minutes and 14   4 minutes, respectively. The mean period of hospitalization was 4 days (range, 3 5 days). Immediate, one-month and late success rates were 96%, 92% and 84%, respectively.


CONCLUSIONS
Percutaneous closure of PDA in adults is a safe and feasible procedure. It should be a reasonable alternative for adult patients who are either not fit for open-chest surgery or who prefer a less invasive approach.
