Structural Heart

This structural heart channel includes news, videos, podcasts and other content related to diagnosis and treatment of structural heart disease. Topics covered include heart valve repair and replacement, transcatheter aortic valve replacement (TAVR), transcatheter mitral valve replacement (TMVR), transcatheter tricuspid valve replacement (TTVR), left atrial appendage (LAA) occlusion, heart failure interventional device therapies, and closing holes in the heart using, including occlusion of atrial septal defects (ASDs), ventricular septal defects (VSDs) and patent foramen ovales (PFOs).

In the LAAOS III trial, surgeons could seal off the LAA during the open heart procedure using sutures, staples or approved closure devices. The image shows a SentraHeart lasso type LAA occluder about to seal off the LAA from the outside of the heart.  #ACC21 #ACC2021

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.

The reSept ASD Occluder is the first structural heart occluder with a metal-free, bioresorbable frame. The novel implant is designed to overcome the limitations of current transcatheter occluders. It is hoped the design will reduce the risk of complications associated with the long-term presence of metal in the heart and to preserve future treatment options requiring transseptal intervention.
