Cardiac Imaging

While cardiac ultrasound is the widely used imaging modality for heart assessments, computed tomography (CT), magnetic resonance imaging (MRI) and nuclear imaging are also used and are often complimentary, each offering specific details about the heart other modalities cannot. For this reason the clinical question being asked often determines the imaging test that will be used.

Better Together? An Integrated Market for Calcium-modification Strategies

Rather than a binary choice—atherectomy or lithotripsy—the market for treating severely calcified lesions seems likely to evolve into a mixture of both technologies. That, in fact, is already occurring. One strategy gaining currency among interventionalists, particularly those in Europe, is to try a high-pressure balloon first in cases of moderately severe calcification and, if the device fails to fully expand, re-enter the vessel with atherectomy.
