Fluoroscopy makes guiding a catheter through a blood vessel possible. However, fluoroscopy, a form of real-time moving X-ray, also exposes the patient to radiation. Now, a University of Missouri School of Medicine researcher has evaluated technology that may be used to replace fluoroscopy, eliminating the need for X-ray during cardiac ablation procedures.

Women undergoing transcatheter aortic valve replacement (TAVR) have better survival rates than men at one year, according to a study published in Annals of Internal Medicine. These results are the opposite of those seen in surgical aortic valve replacement (SAVR), for which female sex has been shown to be associated with poorer outcomes.

Medtronic plc announced the first patients enrolled in the Evolut R FORWARD Clinical Study to evaluate performance outcomes using the CoreValve Evolut R System in everyday clinical practice.

Recent results from the Carotid Revascularization Endarterectomy versus Stenting Trial (CREST) are evidence that stenting will continue to remain competitive with surgical treatment, said an analyst with research and consulting firm GlobalData. CREST data has shown patients with severe carotid artery stenosis suffered similar rates of adverse events in both stenting and endarterectomy procedures.

Brain imaging may accurately identify patients likely to benefit from stroke clot removal instead of relying on the time since symptoms began as an indicator of treatment eligibility. The hypothesis was derived from research presented at the American Stroke Association's International Stroke Conference 2016.
