Interventional cardiology news to note
The Sapien 3 transcatheter heart valve received an expanded indication from European regulators for use in aortic stenosis patients at low surgical risk, Edwards Lifesciences announced.
Percutaneous coronary intervention (PCI) with hemodynamic support -- Impella left ventricular assist device or intra-aortic balloon pump -- for ischemic cardiomyopathy resulted in an absolute 6.5% improvement in left ventricular ejection fraction on average. (Catheterization & Cardiovascular Interventions)
For chronic total occlusion (CTO) PCI, myocardial blood flow recovered to a similar extent no matter the crossing technique employed -- antegrade wire escalation, retrograde wire escalation, antegrade dissection and reentry, or retrograde dissection and reentry. (Circulation: Cardiovascular Interventions)
A novel CTO PCI algorithm incorporating guidewire manipulation time in the choice between primary antegrade, primary retrograde, and rescue retrograde approaches was derived from a Japanese registry of more than 5,000 patients and reported in the Journal of the American College of Cardiology.
The "mothership" pathway to endovascular treatment resulted in shorter onset-to-groin puncture times compared with "drip-and-ship" in the observational NEUROSQUAD study. Transport of a neurointerventionalist to a remote hospital, a strategy dubbed "drive the doctor," was still better than "drip-and-ship." (Stroke)
In its first-in-human study, Selution SLR, a sirolimus-eluting balloon with sustained drug release, was associated with 87.5% freedom from target lesion revascularization out to 2 years, with no events after month 11, a late-breaking presentation showed at the VIVA conference in Las Vegas. The patients, treated for superficial femoral artery lesions, showed an angiographic late lumen loss of 0.19 mm at 6 months.
Also at VIVA was an early feasibility trial suggesting that the LimFlow percutaneous deep vein arterialization system may be beneficial to patients with end-stage chronic limb-threatening ischemia. Amputation-free survival was 74% at 6 months, according to a press release.
