N2 - Background: Controversy remains regarding the use of covered stents in congenital heart disease (CHD). We evaluate the possibilities and safety of covered Cheatham-Platinum (CCP) stents in CHD. Methods: Single-center retrospective CHD-database study of all CCP stents, 2003-2012. Three study groups: aortic coarctation (CoA), right ventricular outflow tract pre-stenting for percutaneous revalvulation (RVOT), and miscellaneous. Continuous data expressed as median (range). Results: 114 CCP stents in 105 patients, age 16.8 years (4.2-71.2). CoA group: 54 CCP stents in 51 patients: 3/54 for aneurysm exclusion, in 51/54 covering used "prophylactically" because of increased risk for vessel tear. Overall, CCP stenting increased the coarctation diameter from 6 mm (0-15) to 15 mm (10-20) (p <0.001). RVOT group: 39 CCP stents in 37 patients (34 with RVOT graft, 3 with transannular patch): the graft lumen had shrunken from nominal 21 mm(10-26) to 13 mm(5-22); with the CCP stent the RVOT was redilated to 22 mm (16-26, p <0.001 vs stenosis). Miscellaneous group: 21 CCP stents in 17 patients: closure of Fontan-circuit fenestration (n =5), restoration of superior caval vein (n=2) or pulmonary artery (n=3) patency, relief of supra-pulmonary stenosis (n =2), exclusion of aberrant pulmonary arteries (n =1), cavopulmonary conduit expansion (n =2), Blalock-Taussig shunt flow reduction (n =1), and defibrillator lead protection from sharp stents (n =1). Hybrid procedures performed in 3/17 patients. CCP stent was used as rescue treatment in 2/patients to seal iatrogenic bleeding. Conclusion: CCP stents can safely be applied in CHD patients. The covering allows adequate sealing of existing or expected tears, thereby increasing the safety margin with more complete dilation.
