— Interventional cardiology news to note
Adding endovascular thrombectomy to the treatment of mild strokes (NIH Stroke Scale scores <6) did not make functional outcomes any better, according to one retrospective analysis in Stroke. M1 occlusions might be an exception, though, with an almost-significant trend toward benefit.
Percutaneous left atrial appendage exclusion lowered systolic pressure in hypertensive atrial fibrillation patients — by 9 mm Hg in 1 year, researchers found in a prospective study. (Journal of the American College of Cardiology)
A French registry study showed that transcatheter aortic valve replacement was often done without balloon aortic valvuloplasty. Procedures had the same efficacy with or without this step, though residual aortic regurgitation rates were even lower in the absence of valvuloplasty, according to the JACC: Cardiovascular Interventions report.
Compared with clopidogrel (Plavix), cangrelor (Kengreal) was tied to fewer periprocedural events during percutaneous coronary intervention (PCI), especially in patients with complex coronary anatomy. (European Heart Journal)
Transcatheter closure is possible for life-threatening ascending aortic pseudoaneurysms, according to two case reports in Circulation: Cardiovascular Interventions. “Technically challenging aortic pseudoaneurysms can be approached with catheters and wires conventionally used in interventional cardiology,” the operators said.
Flow diverter stents used to treat aneurysms are commonly associated with transient in-stent stenosis. One team reported that this is a temporary and asymptomatic finding however, with complete resolution or improvement at long-term follow-up seen in most patients getting dual antiplatelet therapy.

Major complications run high in the initial experience of implanting the Micra transcatheter pacing system, according to real-world experience in Switzerland’s Romandie region. (Europace)
