Extended applications of the Amplatzer vascular plug IV in infants

AbstractObjectiveA variety of devices are available for transcatheter closure of unwanted shunts. We describe our experience with the use of the Amplatzer vascular plug IV in a consecutive series of infants.MethodsA total of eight consecutive infants – all born preterm at gestational ages ranging from 24 to 35 weeks – undergoing transcatheter closure of unwanted shunts – persistently patent arterial duct in five patients, an aorta to right atrium fistula in one, multiple aortopulmonary collateral vessels in one, and an azygos vein to left atrium connection in one – are described. Their age, from birth, ranged between 3 and 11 months, and weight between 2.6 and 11.3 kilograms. All devices were delivered using percutaneous arterial or venous vascular access via a large lumen (0.038 inch) 4-French delivery catheter.ResultsAll lesions could be successfully occluded using one or more devices. Device diameters ranged between 4 and 8 millimetres, and exceeded the minimum diameter of the target vessel by 1 to 2 millimetres. Successful occlusion was confirmed either directly at angiography or on follow-up echocardiography. Of the infants who were mechanically ventilated prior to the procedure, three could be successfully weaned following closure of the shunt. There were no procedure-related complications.ConclusionsThe new vascular plug IV is cheap and efficacious in closing a variety of shunts in young infants, and warrants further extended clinical application.

Amplatzer Vascular Plug Ii

AbstractObjectiveThe aim of this study was to evaluate the safety and efficacy of the Amplatzer Vascular Plug-II used for the closure of perimembranous ventricular septal defects.BackgroundThere are no FDA-approved transcatheter devices for the closure of perimembranous ventricular septal defects. Several studies have reported on the use of various devices either off-label or under clinical trial protocols. However these reports have described significant adverse events including residual shunts, complete heart block, arrhythmia, and new valve regurgitations. Thus far, no study on the Amplatzer Vascular Plug-II has been reported.MethodsWe conducted a 4-year retrospective chart review from August, 2010 to August, 2014, of patients with perimembranous ventricular septal defects associated with ventricular septal aneurysm who underwent transcatheter closure using the Amplatzer Vascular Plug-II.ResultsA total of 16 patients underwent Amplatzer Vascular Plug-II transcatheter closure of their perimembranous ventricular septal defects. The median age was 2.56 years (range: 0.5–27.3). Their median weight was 13.0 kg (range: 6.9–71.6). The left ventricular median defect size was 9.3 mm (range: 5.9–14.4). The right ventricular median defect size was 3.6 mm (range: 2.3–5.8). All the patients underwent successful device implantation with 83% of the patients having complete echocardiographic closure at the 1-year follow-up; however, one procedure was complicated by early device embolisation. The device was successfully retrieved and replaced with a larger device. There were no device-related outflow tract obstructions, rhythm abnormalities, or haemolysis.ConclusionApplication of the Amplatzer Vascular Plug-II for closure of perimembranous ventricular septal defects appears to be a safe and effective treatment option. Prospective clinical trials and longer follow-up periods are warranted.

AbstractLeft ventricular pseudoaneurysm is especially rare in childhood, and its main treatment option should be surgery. We describe the case of a 9.5-year-old boy who first underwent mitral vegetation excision and then an unsuccessful pseudoaneurysm operation. Owing to pseudoaneurysmal sac dimensions, inferior caval vein syndrome developed. We delivered the Amplatzer Vascular Plug 4 into the pseudoaneurysm and treated the inferior caval vein syndrome with a bare Cheatham–Platinum stent. The patient was asymptomatic at the last follow-up.

Abstract An 8-day-old neonate was presented with severe respiratory distress and diagnosed as primary pulmonary hypertension of the newborn on functional echocardiogram. Evaluation showed bounding pulse, enlarged umbilical cord, and bruit over the periumbilical region. Transthoracic echocardiography and CT angiogram showed a large fistulous communication between the umbilical vein and artery suggestive of congenital umbilical arteriovenous malformation leading to high-output cardiac failure and pulmonary artery hypertension. The patient was stabilised with medications and ventilation. Transcatheter closure of communication was done using coils, vascular plug, and KONAR-MFTM device. The patient improved from heart failure soon after the procedure and thriving normally at 6 months of follow-up.

Abstract Acquired and congenital left ventricular to right atrial communication is rare, but nowadays, the frequency of the iatrogenic subgroup is increasing. Successful transcatheter closure of these defects with different devices has been reported. Herein, we presented successful closure of left ventricular to right atrial communication with Amplatzer Duct Occluder 2 after attempting to close with a failed Amplatzer Vascular Plug II device in a 7-year-old girl. This report supports that transcatheter closure of iatrogenic Gerbode defect with Amplatzer Duct Occluder 2 device is safe and effective.
