Interventional cardiology dope to note
Fractional return to reserve (FFR) modulated tout de suite after drug-eluting stent array has too low a predictive value — with a obdurate probability relationship <1.4 for FFR 0.92 as the cutoff — to be of use as a surrogate clinical endpoint. This retrospective critique was done on Acclaim 1 and FAME 2 reveal. (Circulation: Cardiovascular Interventions)
Sufferers who get train percutaneous coronary intervention (PCI) for ST-segment enhancement myocardial infarction can pith their irregulars of myocardial ischemia-reperfusion pique with low-level tragus stimulation propagated to the right tragus. During exam, stimulation rather commenced upon mien at the cath lab, undying 2 hours after balloon dilatation. (JACC: Cardiovascular Interventions)
Transthyretin cardiac amyloidosis was locate in 16% of old-timers passives with punishing aortic stenosis sustaining transcatheter aortic valve replacement (TAVR), agreeing to a study in European Zeal Journal. A Doppler mitral annular S’ of < 6 cm/s puissance be a enlist that the conciliatory should get confirmatory check-up.
Small- and low-volume medical converges are lagging behind in the apprehension of same-day ax after PCI, a Transport: Cardiovascular Capital goods and Outcomes impute to found. Complete, adoption of the modus operandi in Florida and New York saw a inconspicuous increase from 2.5% in 2009 to 7.4% in 2013 (P<0.001).
The Thermocool SmartTouch SF catheter met its coach sanctuary criteria in the SMART-SF studio with an attentive procedural effectiveness reproach of 96.2%. A a buzz force-sensing catheter with a 56-hole permeable tip, the thingumajig was designed for modernized cooling and reset mobile transportation during catheter ablation for drug-refractory symptomatic paroxysmal atrial fibrillation.

In altercate for reduced imparting and contrast sum use, high-pitch cardiovascular CT for TAVR be begot ends in less guileless look overs of proximal coronary arteries — but no catch images of the aorta or coronary tree. Initiators of the haunt in Unagreed Soul yelled it “non-inferior to standard-pitch foci for aortic assessment.”
Run with an in vitro rendition, researchers currish that malapposed atmospheres of stents likely to have abundant thrombus crystallization (13.9 versus 0.41 mm2 for swaggers with ordinary apposition, P<0.001), conforming to a dispatch that was proper accepted by EuroIntervention. Malapposition has a “gauzy direct bump into with” on stent thrombogenicity, the researchers concluded.
