Cath Lab Recap: Lousy Post-PCI Prognostic; High-Pitch CT Quality

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.
