Transcatheter closure of inferior sinus venosus defect using a patent ductus arteriosus occluder following simulation with a 3D-printed model.

ABSTRACT:

Background

Transcatheter closure of inferior sinus venosus defect (ISVD) is still contraindication. To explore whether transcatheter closure with patent ductus arteriosus (PDA) occluders is possible for ISVD.

Methods

From June 2014 to March 2021, 12 patients were recruited diagnosed as <25 mm ISVD. The three-dimensional printing (3DP) heart model was produced based on multi-slice computed tomography (MSCT) scans. Preoperative closure simulation was planned on the personalized 3D model for each patient. Follow-up including electrocardiography (ECG), transthoracic echocardiography (TTE), and X-ray was traced.

Results

3DP models of 12 patients were successfully printed. Twelve patients had been diagnosed with <25 mm ISVD and 4 of them had another secundum atrial septal d
