[Transcatheter interventional therapy of congenital heart disease: the results of Chinese TIT registry].
OBJECTIVE
To report the results of transcatheter interventional therapy (TIT) of congenital heart disease (CHD) register from 23 medical centers in China.


METHODS
In this retrospective multicenter registry study, clinical data from 5808 patients who underwent TIT between January 2008 to December 2010 in 23 Chinese medical centers in 14 cities were analyzed.


RESULTS
Procedure was successful in 5720 cases (98.5%), success rate was 99.5% for PDA, 98.8% for ASD, 97.4% for VSD and 98.5% for pulmonary stenosis (PS). Multivariate regression analysis showed that PDA size and procedure time, age and procedure time, distance from VSD to AV were significantly associated with the procedure success rate of PDA, ASD and VSD closure, respectively. Early complications occurred in 306 cases (5.3%), 36 cases (0.6%) experienced major complications including device embolization in 7 cases, serious aorta regurgitation in 5 cases, serious tricuspid regurgitation in 4 cases, tricuspid stenosis in 2 cases, heart block (HB) in 13 cases (2 in ASD and 11 in VSD), cardiac tamponade in 2 cases (1 ASD and 1 PS) and hemolysis in 3 cases. Procedure time and PDA size, ASD size, device size, age and PS degree were risk factors related to the occurrence of the early complications for PDA, ASD and VSD closure and PBPV respectively. The median follow-up time was 15 months (range 1-36 months). The complete closure rate during follow up was 100% for ASD, PDA and VSD and the pressure gradient in PS decreased to normal range in all PS patients. Late complications occurred in 15 cases (0.2%), of which 3 cases needed surgery intervention and permanent pacemaker was implanted in 1 patient. There was no death during procedure and at follow-up period.


CONCLUSIONS
TIT of CHD offers encouraging results in China. Follow up is warranted to monitor the occurrence of serious complications, especially late complications.
