摘要篇首： Transcatheter occlusion of patent ductus arterious (PDA) using various occluders and coils has been a well-established method1-5 since Porstmann and colleagues6 reported the first case in 1967. However, when patients associated with anomalous inferior vein cava drainage or/and huge high pulmonary artery pressure ductus (HPAP-PDA), the method is not suitable. First, it is unfeasible to carry out the procedure via femoral vein. Second, in the presence of high pulmonary artery pressure such devices including the Amplatzer ductu occluder carry the risk of embolising into the aorta.7 The muscular ventricular septal defect occluder (MVSDO), which is a device for transcatheter closure of muscular ventricular septal defect, may be more suitable for using with HPAP-PDA as its double disk tends to anchor the device, preventing embolisation into the aorta. We present a patient, who is suffering from huge PDA associated with anomalous inferior vein cava drainage and dextrocardia, in whom percutaneous closure of PDA using MVSDO was successfully accomplished via transjugular approach.
