When surgery is not an option: case report of transcatheter valve-in-valve replacement for mitral valve dysfunction

This case highlights the successful application of transcatheter valve-in-valve replacement for a patient with bioprosthetic mitral valve dysfunction who was at high surgical risk. The procedure, performed using a transseptal approach with a 29 mm MyVal valve, resulted in significant symptomatic and hemodynamic improvement with no complications. The patient's functional capacity improved dramatically, and follow-up imaging confirmed the effective functioning of the new valve. This case supports the viability of transcatheter techniques as a preferred alternative for inoperable patients with mitral valve dysfunction, contributing valuable insights to the growing field of minimally invasive cardiac interventions. As technology advances, transcatheter solutions are expected to offer safer and more effective treatments for bioprosthetic valve failures.
