Transcatheter heart valve in valve implantation with Edwards SAPIEN bioprosthetic valve for different degenerated bioprosthetic valve positions (First Iranian ViV report with mid-term follow up)

Abstract: Introduction: After early successful experience with transcatheter aortic valve replacement (TAVR), concept of transcatheter implantation of a new valve within a failing bioprosthetic valve emerged. Valve-in-valve (ViV) implantation seems to be a simpler option for high risk surgical patients. Methods: We performed five ViV procedures in different valve positions. We included patients with failing bioprosthetic valves with high surgical risk due to concomitant comorbidities. We performed 2 transapical ViV pro… Show more

“…The first data of transcatheter valve-in-valve procedure in Iran was reported by Haji Zeinali et al, 17 who showed acceptable midterm results after the valve-in-valve treatment of different failing bioprosthetic valves (2 mitral, 1 pulmonary, and 2 tricuspid valves) in a case series of 5 patients. The patients had manageable postprocedural complications, including pleural effusions and transient ischemic attacks; furthermore, at follow-up, the patients had improved NYHA functional class without paravalvular leakage or valve thrombosis.…”

“…In the Echo assessment of multiple prostheses, the use of multiple and sometimes off-axis views is crucial to overcome the problem of acoustic shadowing, reverberations and mirror artefacts that are more pronounced for mechanical valves. Besides the classical mechanical and bioprosthetic valves, a steady increase in the number of percutaneous procedures is seen each year [64], including the complex transcatheter valve-in-valve and valve-in ring implantations in patients with documented prosthetic valve dysfunction [65]. More long-term outcome data are required in transcatheter aortic and mitral valve interventions which still carry significant peri-procedural risks and often leave varying degrees of residual paravalvular regurgitation [49,62,64].…”
