“…[32][33][34][35][36][37][38][39] During first studies, 30 pigs underwent off-pump mitral valved stent implantation with followup times of 60 minutes and 7 days. Accurate positioning was established in all but 5 animals.…”

“…However, due to the complex anatomic structure of the mitral valve apparatus and the absence of a reliable 'landing zone' [10] , most results are from animal experiments only [7] . VIV and VIR implantation techniques into the mitral position haven been clinically introduced more successfully.…”

“…Transfemoral and transapical transcatheter aortic valve implantation (TAVI) have shown very promising clinical results in selected patient populations. Although transcatheter mitral valve replacement has mostly remained at the stage of animal evaluation [7,8] , transcatheter mitral valve-invalve (VIV) or valve-in-ring (VIR) implantation has slowly entered clinical practice. The VIR technique turns out to be a potential therapeutic technique for high-risk patients with mitral repair failure.…”

and moderate regurgitation in 1. Mean gradients were 6.1 ± 5.0 mm Hg across the device. Postmortem examination confirmed adequate positioning of devices within the annuloplasty ring. Conclusions: This custom-made transcatheter device allows for safe and reproducible off-pump transatrial mitral VIR implantations. Transatrial access is a promising route to facilitate VIR implantations. Our custom-made stent-valve may be suitable for VIR procedures.

“…Seven of the 8 animals died as a result of paravalvular leaks, suboptimal positioning, or failure of fixation. 69 A subsequent bovine pericardial design with a unique ventricular tethering fixation system reduced embolization, and all animals with initially successful implants maintained normal hemodynamics and stability to 8 weeks. 70 Initial first-in-human temporary implants during surgical mitral valve replacement were performed in 2013.…”

“…All patients were considered extreme risk for surgery, and 3 of the 4 died within 3 months post procedure. 69 This group published their initial experience with a transapical, off-pump, porcine self-expanding stent prosthesis in pigs. Seven of the 8 animals died as a result of paravalvular leaks, suboptimal positioning, or failure of fixation.…”
