Study examines efficacy of 3D printing, computer modeling to predict paravalvular leak in TAVR

A new study examines the effectiveness of 3D printing technology and computer modeling to predict paravalvular leak in patients undergoing transcatheter aortic valve replacement (TAVR). A common risk of TAVR is an ill-fitting valve which can lead to PVL.

Trial shows cost-effectiveness of TAVR compared to SAVR in intermediate risk patients with aortic stenosis

Analysis of the PARTNER 2A trial and the SAPIEN-3 Intermediate Risk registry found transcatheter aortic valve replacement (TAVR) to be highly cost-effective compared with surgical aortic valve replacement (SAVR) in intermediate surgical risk patients with aortic stenosis.

New app uses smartphone camera to provide detailed information about heart health

Want to know how healthy your heart is? Now there's an app for that. In a proof-of-concept clinical trial, engineers at Caltech, Huntington Medical Research Institute, and USC have demonstrated that the camera on your smartphone can noninvasively provide detailed information about your heart's health.

Conscious sedation is viable option to general anesthesia for TAVR, UCLA study finds

UCLA scientists have found that conscious sedation -; a type of anesthesia in which patients remain awake but are sleepy and pain-free -; is a safe and viable option to general anesthesia for people undergoing a minimally invasive heart procedure called transcatheter aortic valve replacement.

Elevations in Lipoprotein(a) can be responsible for heart diseases, RI-MUHC study finds

A team of researchers from the Research Institute of the McGill University Health Center found that elevations in a unusual form of cholesterol, called Lipoprotein(a) or Lp(a), as responsible for 1 in 14 heart attacks and 1 in 7 cases of aortic valve disease.

Study reveals risk factors and outcomes of infective endocarditis after TAVR

Among patients undergoing transcatheter aortic valve replacement, younger age, male sex, history of diabetes mellitus, and moderate to severe residual aortic regurgitation were significantly associated with an increased risk of infective endocarditis, and patients who developed endocarditis had high rates of in-hospital mortality and 2-year mortality, according to a study appearing in the September 13 issue of JAMA.

Cerebral protection device reduces brain lesions after TAVI in patients with severe aortic stenosis

Among patients with severe aortic stenosis (narrowing of the aortic valve) undergoing transcatheter aortic valve implantation, the use of a cerebral protection device (a filter that captures debris [tissue and plaque] dislodged during the procedure) reduced the number and volume of brain lesions, according to a study appearing in the August 9 issue of JAMA.
