Structural & Congenital Heart Disease

 

Patients who received a mechanical prosthesis for surgical replacement of aortic or mitral valves derived a significant long-term survival benefit versus those who received a biologic prosthesis, according to a study in the New England Journal of Medicine.

Nearly half of all valve hospitals in the U.S. are misclassified as either low- or high-performing, according to research published in JAMA Cardiology—but that problem might have a simple fix.

DENVER — Transcatheter aortic valve replacement (TAVR) is an “economically dominant” strategy compared to surgical aortic valve replacement (SAVR) for patients with aortic stenosis at intermediate surgical risk, according to data presented by David J. Cohen, MD, MSc, Oct. 31 at the Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium.

Research examining 278 patients with in-stent restenosis (ISR) found that drug-eluting balloon (DEB) was non-inferior in comparison with drug-eluting stent (DES) in terms of six-month minimal lumen diameter (MLD).

DENVER — Measuring frailty could lead to more accurate predictions of outcomes following transcatheter aortic valve replacement (TAVR) than a validated risk algorithm, according to research presented Oct. 30 at the annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium.

CRISPR is capable of targeting specific stretches of genetic code and editing DNA. Researchers have used the tool to erase a genetic mutation that causes hypertrophic cardiomyopathy in human embryos.

Essential Frailty Toolset outperforms others in predicting mortality after TAVR, SAVR

Compared with six other scales that measure frailty, one called the Essential Frailty Toolset stands out for its ability to predict mortality 30 days after two types of valve replacement surgery. It can also predict worsening disability at one year, according to a new study.
