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.

There is a national trend where cardiology is increasingly being called in to help with PE response teams (PERT) at hospitals. Terry Bowers from Beaumont explains what skills interventional cardiologists need for PE procedures.

New atherosclerosis treatment uses ultrasound-assisted lasers to break down plaque

The new technique is still in the development stage, but early research suggests it could provide clinicians with a new treatment option for breaking down arterial plaque.

Eric Williamson, MD, president of the Society of Cardiovascular Computed Tomography (SCCT) and professor of radiology at Mayo Clinic, explains the rapid rise of interest in cardiac CT imaging following its inclusion as a top recommendation in the ACC 2021 Chest Pain Evaluation Guidelines.

3D cardiac modeling solution for VT ablation receives FDA clearance

The new software solution was designed with ventricular tachycardia ablation and other cardiac ablation procedures in mind.

Eric Williamson, MD, MSCCT, the president of the Society of Cardiovascular Computed Tomography (SCCT) and professor of radiology at Mayo Clinic, explains how the iodine contrast shortage is causing issues for cardiac CT imaging. He discusses ways imagers can stretch they iodine contrast supplies and some technologies that might help conserve contrast. #contrastshortage

Eric Williamson, MD, president of the Society of Cardiovascular Computed Tomography (SCCT) and professor of radiology at Mayo Clinic, explains how the iodine contrast shortage is causing issues for cardiac CT imaging and ways this can be mitigated.

A comparison between a traditional iodine contrast angiogram (left), and a gadolinium contrast angiogram (right). MRI gadolinium contrast is starting to be used in some interventional radiology procedures and is being considered in interventional cardiology due to the iodine contrast shortage.

Gadolinium can be used as substitute for iodine contrast in some interventional imaging procedures

Gadolinium might be an alternative, stop-gap solution for interventional procedures during the current iodine contrast shortage.

Left bundle branch block after TAVR hurts outcomes, even when no permanent pacemaker is required

Researchers tracked data from more than 2,000 TAVR patients, focusing on cardiovascular mortality and hospitalizations for heart failure.
