ACC slides: ORBIT II sheds light on atherectomy for calcified lesions

SAN FRANCISCO—ORBIT II, a prospective, multicenter, single-arm clinical trial, was designed to evaluate the safety and efficacy of the Diamondback 360° Orbital Atherectomy System to treat de novo severely calcified coronary lesions. Results presented March 9 by Jeffrey W. Chambers, MD, at the American College of Cardiology (ACC) scientific session showed that the trial met its primary safety and efficacy endpoints: 30-day major adverse cardiac events (cardiac death, MI, target lesion revascularization) and procedural success.

Eleven medical societies have signed on to a consensus statement aimed at standardizing imaging for suspected cardiovascular infections.

Kate Hanneman, MD, explains why many vendors and hospitals want to lower radiology's impact on the environment. "Taking steps to reduce the carbon footprint in healthcare isn’t just an opportunity," she said. "It’s also a responsibility."
