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.

Patients can safely undergo noncardiac surgeries after TAVR without a long delay

However, the study’s authors did find associations between suboptimal TAVR procedures and adverse outcomes.

The Corvia Atrial Shunt is designed to address elevated left atrial pressure (LAP) heart failure patients.

VIDEO: Overview of intra-atrial shunts to treat heart failure

Cardiologist Peter Fail, MD, discusses the idea of using shunts to form a passage that enables the left atrium to decompress at rest and during physical activity. The goal is to lower left atrial pressure in heart failure patients.

Radiation exposure during structural heart procedures much higher for echocardiographers than cardiologists

The new analysis focused on transcatheter edge-to-edge repair and left atrial appendage occlusion procedures.

The projected number of acquired cardiomyopathy cases are expected to greatly outpace the number of new familial cardiomyopathy cases by 2031 in the U.S., driven mainly by poor lifestyles. This is expected to have a big impact on healthcare.

U.S. expected to see large rise in cardiomyopathy cases over next decade

“Even if we compensate for the differences in population size, the U.S. is still miles ahead when it comes to total cardiomyopathy cases," explained Walter Gabriel, MPH, an epidemiologist and analyst on the report.

New LAA occluder technology and the debate on echo vs. CT image guidance

At TVT 2022, there was debate whether CT imaging is needed for preplanning LAA procedures, and several new devices in development were discussed.

“We need an answer now”: Cardiologist awarded $2.3M to study cannabis use and heart health in people living with HIV

The four-year analysis will use cardiac MRI scans to closely monitor the heart health of people living with HIV who regularly use cannabis to treat their symptoms.

AFib patients more likely to be hospitalized for heart failure or bleeding following TAVR

The study, published in the American Journal of Cardiology, included data from more than 900 TAVR patients. Overall morality was 22.7% among patients with AFib and 14.4% among patients without AFib.

Leadless pacemaker technology moves toward dual-chamber pacing

Leadless pacemaker technology is expanding its ability to treat more patients with dual-chamber pacing.
