A sirolimus-coated stent featuring a luminal anti-CD34+ antibody layer to attract endothelial progenitor cells for better healing showed no stent thrombosis beyond day 9 of implantation through to 1 year, the REMEDEE registry study found.
Could the National Security Agency know if you have atrial fibrillation? A team of researchers was able to make an educated (and correct) guess in one case based on the kind of meta-data available to the agency. The tell: record of a call to a cardiac monitoring device hotline.
Women got more meaningful prognostic information from CT angiography than from stress testing in a randomized investigation (P=0.028). Men, on the other hand, seemed to glean as much from either modality.
Patients with hypertrophic cardiomyopathy were twice as likely to relapse after catheter ablation for atrial fibrillation as those without the cardiomyopathy, a meta-analysis found. These patients also needed more repeat procedures and antiarrhythmic drugs following intervention.
A system for endovascular repair of infrarenal abdominal aortic aneurysms (AAAs) had only a 3.1% rate of endoleaks at 1 year in the EVAS FORWARD-IDE trial, which was “the lowest rate ever reported for an IDE study of an endovascular AAA device,” according to a company release. And freedom from device-related reintervention came in at 96.6%.
The FDA warned of heart infections from the 3T heater-cooler tank by Sorin/LivaNova due to aerosolized M. chimaera, particularly for patients getting a heart valve or other cardiac prosthesis.
After surgical aortic valve replacement for severe aortic stenosis, irreversible impairment of left ventricular (LV) global longitudinal strain persists for about 20% of patients despite LV mass regression and preserved LV ejection fraction and is tied to more adverse events, a hypothesis-generating study showed.
