Structural Heart


WASHIINGTON, D.C.—Transcatheter aortic valve replacement (TAVR) added more than two years to the life of inoperable patients with severe aortic stenosis, according to five-year results of the PARTNER I trial presented Sept. 13 at the Transcatheter Cardiovascular Therapeutics scientific session. The device also showed good durability, researchers said.

 - CoreValve

A meta-analysis of predictors of permanent pacemaker implantation after transcatheter aortic valve replacement (TAVR) reinforced findings that patients treated with the CoreValve device were at increased risk compared with patients receiving the Sapien device. The predictors may help physicians avoid atrioventricular block-related complications, regardless of device type.

 - Heart

Patients with baseline stenosis or small surgical valves who undergo transcatheter aortic valve-in-valve implantation for failed bioprosthetic devices have lower survival rates than the overall patient population, according to a study published in the July 9 issue of JAMA.


Limiting access to transcatheter aortic valve replacement (TAVR) therapy to inoperable patients suitable for only a transfemoral approach reduced the number of patients who received care, particularly women, in a study that evaluated the effect of the national coverage determination (NCD).

Children’s hospital physicians cautioned surgeons against implanting the Mitroflow bioprosthetic aortic valve in young patients who undergo aortic valve replacement and recommended vigilant surveillance of those who already have the device.
