Abstract
Background: Stent implantation has become the preferred method of treatment for treating vessel stenosis in congenital heart diseases. The availability of covered stents may decrease complications and have an important role in the management of patients with complex anatomy.
Aim: This study aims to evaluate the feasibility and safety of the pre-mounted cobalt-chromium stent-graft-covered ePTFE Aortic BeGraft in a broad spectrum of vascular lesions.
Methods: This is a multicenter retrospective results analysis of 107 implanted BeGraft stents between 2016 and 2022 in six different European centers.
Results: One hundred and four patients with a mean age of thirteen years (range 1-70 years) and with the body weight of 56.5 kg (range 11-115 kg) underwent the BeGraft stent implantation. Stents were implanted in the following conditions: aortic coarctation (74 patients), RVOT dysfunction (12 patients), Fontan circulation (7 patients), and miscellaneous (11 subjects with complex CHD). All the stents were implanted successfully. The median stent diameter was 16 mm (range 7-24 mm), and the median length was 39 mm (range 19-49 mm). Major complications occurred in five subjects (4.7%). During a median follow-up of fourteen (1-70) months, stents’ re-dilatation was performed in five patients.
Conclusions: The BeGraft stent can be used safely and effectively in a wide spectrum of congenital heart diseases. Whether these good results will be stable in the longer term still needs to be investigated in a follow-up given its recent introduction into clinical practice, in particular regarding stent fracture or neointimal proliferation.
