Patients who receive embolization coiling for brain aneurysms and other vascular abnormalities may have magnetic resonance angiography artifacts down the line, potentially subjecting them to inaccurate clinical diagnoses. Coils with 304V stainless steel were singled out for this risk in an FDA MedWatch alert.

The non-invasive instantaneous wave-free ratio is a cheaper alternative to fractional flow reserve measurement, according to a DEFINE-FLAIR analysis presented at the American College of Cardiology (ACC) meeting. (Healio)

Also reported at ACC were randomized data suggesting that transcatheter aortic valve replacement (TAVR) with the CoreValve left patients with a similar risk of mortality over 5 years but better hemodynamic performance compared with surgery, the device’s manufacturer, Medtronic, announced.

Neither procedure nor lesion characteristics changed the finding that rivaroxaban was better than warfarin plus dual antiplatelet therapy for antithrombotic safety among patients with atrial fibrillation who got percutaneous coronary intervention (PCI). (JACC: Cardiovascular Interventions)

The utility-weighted modified Rankin Scale was not better at detecting treatment effects of stroke intervention and may even reduce the statistical power of a trial, according to a MR CLEAN analysis published in Stroke.

That women are at higher mortality risk after PCI can be largely attributed to noncardiac deaths. In the 2006-2012 period, cardiac deaths constituted a minority of mortalities observed: 33.8% in women and 38.0% in men. (Circulation: Cardiovascular Interventions)

Investigators found that the BioNIR ridaforolimus-eluting stent was noninferior to Resolute Integrity in terms of in-stent late lumen loss at 6 months. Clinical outcomes were also similar at 1 year, the team’s first-in-human trial showed. (EuroIntervention)
