Cath Lab Recap: TAVR For Bicuspid Valves; Optimized OHCA Protocol

The PK Papyrus Covered Coronary Stent System is now approved for treating acute coronary artery perforations, which can occur during percutaneous coronary intervention. The system comes with a balloon-expandable covered coronary stent that acts as a physical barrier to seal the torn artery wall.

Revised labeling gave intermediate- and high-risk patients with bicuspid severe aortic stenosis access to the CoreValve Evolut system transcatheter aortic valve replacement. Manufacturer Medtronic also got FDA approval for a single-arm study of the device in low-risk patients who have bicuspid aortic valves. (MassDevice)

A German institution improved survival in out-of-hospital cardiac arrest patients after implementing a strict protocol of mandatory therapeutic hypothermia and cardiac catheterization, according to a report in JACC: Cardiovascular Interventions.

Transcatheter mitral valve replacement can be performed with transatrial access in the setting of severe annular calcification, operators said. (Journal of the American College of Cardiology)

In Sweden, the same non-ST-elevation MI (NSTEMI) patients who had a mortality rate of 33.0% in 1995-1996 would have had risk drop to 25.0% in 2013-2014. The improvement was linear across time and could be attributed to more in-hospital coronary interventions and better medications in recent years. (European Heart Journal)

Sirolimus-eluting stents continually develop neoatherosclerosis more than 10 years after implantation, researchers reported in EuroIntervention. Time did not make for more uncovered stents or stent malapposition, on the other hand.

Real-world experience confirmed that thrombectomy 6-24 hours after stroke onset can still produce good results. Researchers based this on pooled NASA and TRACK registry data. (Journal of NeuroInterventional Surgery)
