AI-powered MRI evaluations predict STEMI outcomes better than existing risk scores

Researchers found that their advanced machine learning model consistently outperformed current risk stratification techniques.

TAVR linked to higher reintervention rate than SAVR in Evolut Low Risk trial update

The Evolut Low Risk trial has been one of cardiology’s most closely watched studies for years now. For the first five years after treatment, TAVR and SAVR were associated with comparable outcomes when treating low-risk patients. In this new six-year update, however, TAVR was linked to a heightened risk of reintervention not seen with SAVR. 

Researchers in the U.K. from Newcastle University, University of Leeds, and the University of East Anglia found they could use cardiovascular magnetic resonance (CMR) T2 intracardiac blood pool data to create imaging-derived SvO2 (iSvO2) noninvasively.

MRI scans evaluate heart failure risk—no invasive catheterization required

Advanced imaging may be able to help certain heart patients avoid the risks and discomfort associated with right heart catheterizations.

Siemens Healthineers partners with prominent health system to advance precision care

The duo plan to establish a global center of excellence in theranostics, taking advantage of Siemens’ state-of-the-art technology and software to advance the use of radiopharmaceuticals in cancer care.

Andres Cordova, MD, cardiology fellow, University of Vermont Medical Center, explains a study of registry and outcomes data on the use of Impella hemodynamic support in elderly STEMI patients with cardiogenic shock.

Impella use fails to improve mortality in elderly patients

The Impella CP heart pump is being used more and more to treat cardiogenic shock, and the benefits are clear. For many older patients, however, the technology seem to fall short.
