Cardiology (Heart) - ASD, VSD, PDA Device Closure
ASD The catheter is positioned at different chambers of your heart to measure the pressure and oxygen content prior to device closure. Sometimes, balloon sizing of the ASD may be required. The appropriate size device is connected onto a cable, put into a special delivery tube, advanced through your ASD and carefully deployed. VSD The Amplatzer muscular VSD occluder may be used to close certain VSDs. It is shown to have full closure of the VDS within the 24 hours of placement. It has a low risk of embolism after implantation. Some tricuspid valve regurgitation was shown after the procedure that could possibly be due from the right ventricular disc. PDA This procedure is usually done in infants or children who are large enough to have the procedure. Through the catheter, a plug or coil is inserted to close the ductus arteriosus. Usually the procedure is done on an outpatient basis, if no complications arise, and the child can be taken home the same day.
