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.

Performing CT-derived fractional flow reserve (CT-FFR) before transcatheter aortic valve replacement (TAVR) improves the accuracy of coronary CT angiography (CCTA) and helps limit unneeded invasive coronary angiography (ICA), according to a new study published in JACC: Cardiovascular Interventions.

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.

Transcaval TAVR outperforms transaxillary TAVR when femoral access is not an option

Transcaval TAVR was linked to a much lower stroke rate and fewer bleeding complications.

The Shockwave Medical M5+ new peripheral intravascular lithotripsy (IVL) catheter cuts procedures times in half and was showed for the first time at the American College of Cardiology (ACC) 2022 meeting. It is designed to break up calcium in heavily calcified arteries to avoid the need for vessel trauma caused by high pressure angioplasty.

New cardiac MRI analysis offers updated insight into long-term impact of vaccine-related myocarditis

Months after their initial myocarditis diagnosis, late gadolinium enhancement (LGE) was observed in 62% of patients on follow-up cardiac MRI.

Eleven medical societies have signed on to a consensus statement aimed at standardizing imaging for suspected cardiovascular infections.

Kate Hanneman, MD, explains why many vendors and hospitals want to lower radiology's impact on the environment. "Taking steps to reduce the carbon footprint in healthcare isn’t just an opportunity," she said. "It’s also a responsibility."
