Use of manual aspiration thrombectomy during percutaneous coronary intervention for ST-segment elevation MI has fallen by more than 50% since 2011, a large registry study showed in JAMA Cardiology. When it was used, patients had a small increase in in-hospital stroke risk.
The Society of Cardiovascular Computed Tomography recommended an expanded role for CT in transcatheter aortic valve replacement (TAVR) in a consensus document. (Journal of Cardiovascular Computed Tomography)
For symptomatic chronic internal carotid artery occlusions, a hybrid operating room allowing for endovascular therapy and endarterectomy in the same session was associated with an 83.3% technical success for procedures, according to a small study. (Journal of NeuroInterventional Surgery)
The repositionable Lotus valve was associated with a 1-year permanent pacemaker rate (PPM) of 32% in the RESPOND registry. With the addition of the Depth Guard feature to the device, the 30-day rate was 18% in the 50-person RESPOND extension cohort, according to the report in JACC: Cardiovascular Interventions.
Smaller infarcts on follow-up only partly explain the improved functional outcomes 90 days after endovascular therapy for acute ischemic stroke. “Follow-up infarct volume as measured on CT and MRI is not a valid proxy for estimating treatment effect in phase II and III trials of acute ischemic stroke,” researchers concluded.

TAVR patients who were discharged to a location other than home were more likely to die within the year, researchers reported in Catheterization and Cardiovascular Interventions.
