Permanent pacing is often required following the Fontan operation and is usually performed epicardially as there is no direct access to the ventricle from the systemic veins. Dual chamber endocardial pacing was achieved by the transhepatic approach in two children with Fontan circulation. The patients were a 7 year old boy with left atrial isomerism, single(More)
OBJECTIVE Most devices devices available for percutaneous closure of Fontan fenestrations tend to be bulky. The aim of this study was to evaluate a low profile custom made device and assess its efficacy and safety. PATIENTS AND METHODS A 15 mm PFO star was used as the basis. The following modifications were made: removal of the left disc to reduce(More)
AIMS Patients with cryptogenic embolic events and a patent foramen ovale (PFO) are at risk of paradoxical embolism causing recurrent cerebral events; however, transcatheter PFO closure remains controversial. The aim of this multicentre trial was to demonstrate the feasibility and safety of transcatheter closure of PFO with the HELEX Septal Occluder. (More)
Two patients, a 5 year old boy with progressive hypertrophic obstructive cardiomyopathy and increasing symptoms despite appropriate pharmacologic therapy and an 11 year old girl with symptoms of tiredness and peak instantaneous LVOT gradient of 80 and 90 mmHg respectively were considered for radiofrequency catheter septal ablation, to relieve the left(More)
We report two cases of transcatheter-device closure of aortopulmonary windows, a residual defect occurring after previous surgical closure, and a native lesion. The postsurgical defect was closed with an Amplatzer Duct Occluder II (AGA Medical Corporation, MN). The native lesion was not suitable for an Amplatzer Duct Occluder II device; thus, it was closed(More)
