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.

Key interventional cardiology takeaways from ACC.22

Several late-breaking clinical trials at ACC.22 will likely impact clinical practice. Below are summaries of a few key trials and their takeaways for interventional cardiology and structural heart interventions.

An implantable cardioverter defibrillator (ICD) and its associated leads viewed on a X-ray. Old leads are often abandon in veins and new ones added, but a new study of 1 million patients at ACC22 showed there is higher mortality if a device becomes infected and the leads are left behind.

VIDEO: Lowering mortality rates from infected EP implantable cardiac devices

Sean Pokorney, MD, director of the arrhythmia core lab, Duke Clinical Research Institute, assistant professor of Medicine, Duke University, discusses a late-breaking ACC 2022 study that shows mortality is higher in patients with implantable electrophysiology (EP) device infections where the leads are not explanted.
