TCT-775 Validation Study of Intra-Cardiac Echocardiography in Trans-Catheter Closure of Patent Ductus Arteriosus

Although aortography is the standard imaging modality in transcatheter closure of patent ductus arteriosus (TC-PDA), aortography cannot always visualize PDA clearly in adult patients and is precluded in patients with renal dysfunction. The purpose of this study was to validate intracardiac
