    ABSTRACT: Background: Total cavopulmonary connection (TCPC) is performed in patients having a single ventricle to allow the passive flow of systemic venous blood to the lungs. Interventional catheterization is needed to treat residual defects or complications. Aims: We discuss our results concerning 68 patients who had had TCPC from January 1995 to December 2010. Methods: Initial and follow-up catheterization data were reviewed retrospectively. Mid-term results were evaluated by means of angiography and/or CT scan. Results: Mean age at TCPC was 5 years (2.5-18); mean interval between TCPC and catheterization was 5.6 years (1.5-15). Sixty-nine catheterizations were performed in 53 patients. Eleven patients (21%) had low venous pressure, did not display a right-to-left shunt, and did not need any intervention. Fifteen patients (28%) had low venous pressure and only needed the closure of the fenestration. The remaining 27 patients (51%) needed the following interventions: embolization of venous vessels prompting right-to-left shunt (n = 15), stenting or reconnection of pulmonary arteries (n = 5), stenting or recanalization of systemic veins (n = 11), other procedures (n = 5). In 3 patients the fenestration could not be closed due to high venous pressure. After the interventions oxygen saturation increased from 90.5%± 4.8% to 94.7%± 3.6% (P = 0.002). Conclusions: Our data show that 49% of patients with TCPC are in good condition late after surgery. However, half of these patients continue to need interventions generally aimed at suppressing stenoses at various levels of TCPC or at occluding vessels prompting right-to-left shunt. This population should enter a multicenter program aimed at identifying patients at risk. (J Interven Cardiol 2012;**:1-6).

    ABSTRACT: Limited data exists on midterm results concerning paediatric interventions on stenotic or occluded systemic veins following indwelling lines, cardiac surgery, or catheterisations. The purpose of this study was to report our acute and intermediate results concerning patients with (Group A) and without (Group B) congenital heart diseases (CHD) over a 10-year period. From January 2000 to December 2010, 32 patients (23 in Group A and nine in Group B, respectively) underwent 39 interventional catheterisations aimed to dilate or recanalise occluded iliofemoral veins, inferior or superior venae cavae. Initial and follow-up catheterisation data were reviewed retrospectively. Midterm results were evaluated by means of echography, angiography, and CT scan in all 15 and 17 patients, respectively. Median age and weight of all patients at catheterisation were five years (range 0.1-18) and 15 kg (range 2-60), respectively. Fifty-two stents were implanted in 29 patients (32 vessels). In 25 patients 28 vessels were occluded and required recanalisation. There were no major complications. In all but three patients it was possible to treat the lesion. There were two procedural complications (5.1%): one acute stent occlusion and one local dissection. At a median follow-up of 2.5 years (range 1-10) we observed six complications of stenting (11.5%): two fractures, two occlusions and two restenoses. Interventional catheterisation of stenotic or occluded systemic veins grants good immediate results at a low rate of complication. Stent dilatation or recanalisation may open the vessel for use during future procedures. However, long-term results are yet to be established.

    ABSTRACT: The objective of this study was to evaluate the technical feasibility, safety, and efficacy of the new device Amplatzer duct occluder II additional sizes (ADO II AS) for closure of patent ductus arteriosus (PDA). Background: Transcatheter device closure is the standard care for PDA. Currently available technology is not designed for closure of small PDA in young children. From April to July 2011, seven children (five females, median age 1.5 years, median weight 11.4 kg) underwent PDA closure with the ADO II AS. Six had isolated PDA, one had PDA associated with preductal coarctation. We evaluated early and short-term results. All but one PDA was closed via an antegrade approach. Mean fluoroscopy and procedural times were 8.0 ± 3.9 and 49.8 ± 27.9 min, respectively. No complications occurred. Immediate trivial residual shunt was present in one patient. In all devices, the retention disks laid flat against the walls of the pulmonary artery and aorta, without protrusion into the vessel lumen. The echocardiography performed after 24 hr did not show any residual shunt. At a median follow-up of 2 months, the PDAs were completely occluded without obstruction of the pulmonary arteries or aorta. The new device ADO II AS was safely deployed with complete resolution of the PDA shunt. The lower profile and symmetry of this device allows for venous or arterial approach and smaller delivery catheter size. The ADO II AS might be a preferable alternative for closure of small-moderate PDAs.
