Interventional cardiology news to note
Areas with the heaviest air pollution also had the highest rates of percutaneous coronary intervention (PCI) for acute coronary syndrome in a Polish epidemiological study. But cleaner air was associated with greater sensitivity to fluctuations in particulate matter in the study, slated for presentation at the European Society of Cardiology meeting in Paris.
A new 3D MRI computing technique for myocardial tracking and cardiac strain estimation takes away the need for gadolinium. (Scientific Reports)
Patients discharged on anticoagulants
after aortic valve replacement did not suffer more adverse outcomes at 1 year than those who did not receive early anticoagulation in pooled analysis of PARTNER II trials and registries. Anticoagulation was even associated with lower stroke risk after surgery. (Journal of the American College of Cardiology
Researchers created a model to predict paclitaxel levels in tissue following paclitaxel-coated balloontherapy for peripheral artery disease. The model takes into account dosing and the kinetics of tissue retention and coating dissolution. (Journal of Controlled Release)
Of patients screened for transcatheter mitral valve replacement at two French centers, 60% were ultimately refused the procedure, mostly because their anatomy -- a mitral annulus that is too big, perhaps, or a risk of neo-left ventricular outflow tract obstruction -- was not amenable to available devices. This suggests the need to design new prosthesis for these patients, researchers suggested in their EuroIntervention report.
The bioresorbable-polymer Synergy stent continued to match the durable-polymer Promus Element Plus in rates of target lesion failure (14.3% vs 14.2%) and stent thrombosis (0.7% vs 0.9%), according to 5-year data from EVOLVE II. (Circulation: Cardiovascular Interventions)
Dips in blood pressure during stroke thrombectomy were associated with worse subsequent functional outcome in some, but not all, studies in a systematic review published in Stroke.
