Transcatheter Systemic AV Valve-in-Valve Implantation in a Patient With LTGA and Ebstein Anomaly

We present the first in-human transcatheter systemic atrioventricular valve-in-valve implantation in a 37-year-old patient with Ebstein anomaly, levo-transposition of the great arteries, and prior systemic valve replacement. She had severe bioprosthetic valve regurgitation and reduced systolic function. She had high surgical risk and was planned for transcatheter intervention. (Level of Difficulty: Advanced.)

Percutaneous techniques for treatment of tricuspid valve dysfunction in congenital heart disease - an emerging therapy

Introduction: Tricuspid valve (TV) dysfunction treatment experiences exponential growth of the interest over the last years. New techniques for percutaneous tricuspid valve treatment are either on the market or in the early stages of development.Areas covered: Deficiency of uniform guideline-based recommendations leads to diverse TV dysfunction treatment options. The current review describes the development of surgical techniques for TV dysfunction in Ebstein's anomaly and transition to a variety of new technologies. Then, the focus is on the potential of percutaneous interventions to reduce the total number of open-heart surgeries in patients with congenital heart disease (CHD) after TV replacement with a bioprosthesis to improve TV function.Expert opinion: TV dysfunction is usually a complex combination of anatomical cardiac features in CHD. Compared to adults with secondary TV dysfunction, CHD patients usually are younger and have experienced several open-heart surgeries at a young age. Therefore, TV dysfunction can affect long-term life expectancy and quality of life significantly. So far, surgery was the gold standard for TV dysfunction treatment. The duration of TV plasty or bioprosthesis is limited, while the risk of re-do operations increases with every procedure. Percutaneous TV implantation may reduce the total number of open-heart surgeries over a patient's life.
