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.

A key update: 1 year later, no signs of long-term heart damage among college athletes who had COVID-19

More than 3,500 college athletes with a confirmed COVID-19 diagnosis were included in the new study. The median follow-up period was more than one full year.

TAVR safe and effective for patients with mixed aortic valve disease

MAVD patients did face a higher risk of requiring a permanent pacemaker, researchers noted, though the reason for this trend remains unclear.

State of the industry: 7 big takeaways from a new report on salaries and job satisfaction in cardiology

With physician burnout on the rise and a massive physician shortage on the way, it’s more important now than ever to keep a close eye on how the country’s cardiologists—and their colleagues—are being paid.

CT-FFR before TAVR improves detection of coronary artery disease, limits invasive imaging exams

CT-FFR, which recently got a boost from the 2021 AHA/ACC chest pain guidelines, could play a key role for clinicians hoping to screen TAVR patients for coronary heart disease.
