Percutaneous treatment with the ‘valve-in-valve’ technique in congenitally corrected transposition of the great arteries and systemic atrioventricular valve with severe double lesion: case report

Although percutaneous interventions for systemic tricuspid valve disease have been described, they typically involve native valves and remain anecdotal. To date, no published reports have documented valve-in-valve implantation in a systemic AV prosthesis in a patient with CCTGA. This case illustrates the feasibility and safety of such an approach in a high-risk patient, offering a valuable alternative to surgical replacement and potentially delaying the need for heart transplantation.
