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.

ABSTRACT:

Background

Congenitally corrected transposition of the great arteries (CCTGA) is a rare congenital heart disease characterized by atrioventricular (AV) and ventriculoarterial discordance, allowing near-normal circulation without early surgical correction. However, long-term complications such as valvular dysfunction, systemic right ventricular (RV) failure, and pulmonary hypertension are common. Management becomes particularly challenging in patients with prior interventions, where anatomical complexity and elevated surgical risk limit therapeutic options.

Case summary

We present the case of a 47-year-old Chinese female diagnosed with CCTGA who had previously undergone surgical implantation of a bioprosthetic valve in the systemic AV position in her home country. She present
