The Early Bird Bleed Monitoring System got FDA approval for the detection and monitoring of vessel injury-related bleeding during endovascular procedures, manufacturer Saranas announced. Clearance for its de novo designation was based on an animal study.
Among Medicare and Medicaid beneficiaries, drug-eluting stents were not associated with mortality when placed for peripheral artery revascularization, a report showed in the Journal of the American College of Cardiology. Medpage Today has full coverage here.
One way to prevent reduced sinus flow, which has been implicated in subclinical leaflet thrombosis after transcatheter aortic valve replacement (TAVR), may be leaflet laceration to allow direct flow between the neosinus and the sinus, a simulation study suggested.

Even in ASPECTS 0-5 stroke patients, successful mechanical thrombectomy reperfusion was associated with favorable outcomes and no higher risk of symptomatic intracerebral hemorrhage, pooled analysis of several institutional registries showed. (Stroke)
A closure device built for transcaval access achieved 100% technical success in TAVR, according to first-in-human research presented at the Cardiovascular Research Technologies meeting. (CRTonline.org)
Two layers of bare metal stents together over a covered stent for coronary artery aneurysm treatment could offer flexibility and easier deliverability. In a case series from China, all nine patients treated with this approach got successful stent placement and were symptom-free at 6 months. (EuroIntervention)
Coronary flow indices with the best test-retest repeatability were fractional flow reserve, absolute coronary blood flow, and absolute microvascular resistance, according to lab experiments. Reproducibility was weaker for the index of microvascular resistance and poor for coronary flow reserve. (Catheterization and Cardiovascular Interventions)
