Interventional cardiology news to note
Cardiovascular trials used to support current guidelines on myocardial revascularization have a robustness problem: over a quarter of these studies would have had statistically significant results rendered nonsignificant if just three patients without events did have events after all. This number, known as the frailty index, was lower than the number of people lost to follow-up in more than 40% of trials, according to a report in Circulation: Cardiovascular Quality and Outcomes.
Women were less likely than men to have non-ST-segment elevation acute coronary syndromes treated with aspirin, P2Y12 inhibitors, and statin therapy across the TIMI trials. Women also got less coronary angiography and percutaneous coronary intervention (PCI). (Journal of the American College of Cardiology)
European countries where PCI is most frequent are Austria, Bulgaria, and Germany. Switzerland and Germany were noted for having particularly high rates of transcatheter valve procedures. (European Heart Journal)
In selected patients with multivessel disease, hybrid coronary revascularization combining PCI and coronary artery bypass grafting (CABG) resulted in shorter postoperative recovery and no worse outcomes than off-pump CABG alone, showed a single-center report in the Journal of the American Heart Association.
Post-procedural stroke rates tend to be lower after MitraClip repair than mitral valve surgery, according to a meta-analysis published in EuroIntervention. Researchers said they noted more new-onset atrial fibrillation after surgery.
"ARAHKEY" is a novel technique for transcatheter aortic valve replacement access site closure in which the Exoseal device is used to deliver a plug when hemostasis cannot be achieved with the ProGlide suture-mediated device. (Catheterization & Cardiovascular Interventions)
Stroke patients getting endovascular treatment are no exception to the association between higher blood pressure variability and worse functional outcome at 90 days, according to a post hoc analysis of the BEST trial. (Stroke)
