Heart Valve Technology

This channel includes news and new device innovations about heart valve technologies, including the aortic valve, mitral valve, pulmonic valve, and tricuspid valve. This includes information on transcatheter valve technologies like transcatheter aortic valve replacement (TAVR, or implantation TAVI), transcatheter mitral valve repair or replacement (TMVR), transcatheter and surgical valve repairs, and surgical replacement valves. Newer devices are now being used for transcatheter tricuspid valve repair replacement (TTVR).

Explaining the Emory TMVR angle. Discordance between mitral annular centerline (yellow lines) and valve orientation imposed by guidewire position within the LV apex (red dashed lines). (B) Valve intrinsic angle (α) is determined by external skirt height. (C) When annular-apical “Emory” angle (red curves) exceeds α (blue curve), annular skirt apposition is not possible, causing PVL (red arrows). (D) The valve is oriented perpendicular to the annual plane using an exteriorized apical guidewire.

University of Minnesota researchers used a hybrid of tissue engineering and regenerative medicine to create heart valves that can grow with the recipient. When implanted in lambs, researchers showed that the tri-tube valves worked better than current animal-derived valves with almost none of the calcification or blood clotting that the other valves showed. This can be implanted in pediatric patients with congenital heart diseas. Photo from Syedain, et al., Tranquillo Lab, University of Minnesota
