• Cath Lab Recap: Impella OK'd, CIN Device, Non-Invasive FFR Interventional cardiology news to note

    The FDA gave the Impella heart pumps the green light for treating cardiogenic shock, making these the only percutaneous temporary ventricular support devices approved for this indication.

     

    Also getting a thumbs up from the FDA was the Micra Transcatheter Pacing System. “As the first leadless pacemaker, Micra offers a new option for patients considering a single chamber pacemaker device, which may help prevent problems associated with the wired leads,” William Maisel, MD, MPH, of the FDA, said in a press release.

    But it’s a Class I recall for the Guardian II Hemostasis Valve for preventing blood loss during catheterization. Device maker Vascular Solutions cited a defect in the low-pressure seal that would potentially allow for air embolism.

     

    Transcatheter aortic valve replacement (TAVR) for a patient at risk of contrast-induced acute kidney injury? There could be a device for that. The RenalGuard System may prevent nephropathy by inducing high urine rates, a small study suggested.

     

    Fears of terrorist attacks in Europe have led to the cancellation of EuroPRevent. The European Society of Cardiology had originally slated the conference for May 4-7 in Istanbul.

     

    Two predictors for mortality after PCI of the unprotected left main emerged in a population-based registry: pre-procedural ventilation (for patients with non-ST-segment elevation acute coronary syndrome and ST-segment elevation myocardial infarction [STEMI] without cardiogenic shock) and TIMI flow (for those with STEMI coupled with cardiogenic shock).

     

    A non-invasive measurement of fractional flow reserve worked well as a tool when selecting intermediate stenosis patients for catheterization. The technology takes advantage of coronary CT, in lieu of invasive coronary angiography.
