Abstract

Abstract: The Melody ® transcatheter pulmonary valve system was developed for placement within right ventricle-to-pulmonary artery conduits in patients with CHD for treatment of stenosis or regurgitation, providing an alternative to open-heart surgery. Abnormal systemic venous connections altering the catheter course to the right ventricle-to-pulmonary artery conduit may present a challenge to Melody ® valve implantation. We present two such cases, in which the Melody ® valve was successfully implanted in teenage patients with congenitally corrected transposition of the great arteries after Senning atrial switch operation. Despite the abnormal catheter course, the right ventricle-to-pulmonary artery was approachable via the right femoral vein allowing for deployment of the Melody ® valve in the appropriate position. This suggests that systemic vein-to-left atrium baffles are not prohibitive of Melody ® valve implantation. This is an important implication considering the substantial population of ageing patients with CHD who have undergone atrial switch. Melody ® valve implantation can be considered as a viable option for treatment of these patients if they develop right ventricle-to-pulmonary artery conduit failure.
