• CHD
• transcatheter valve implantation
• pulmonary valve intervention

The Melody (R) 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 (R) valve implantation. We present two such cases, in which the Melody (R) 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 (R) valve in the appropriate position. This suggests that systemic vein-to-left atrium baffles are not prohibitive of Melody (R) valve implantation. This is an important implication considering the substantial population of ageing patients with CHD who have undergone atrial switch. Melody (R) valve implantation can be considered as a viable option for treatment of these patients if they develop right ventricle-to-pulmonary artery conduit failure.
