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.

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.

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.

Is PCI without stenting safe for low-risk STEMI patients?

The study's authors examined data from the DANAMI-3 trial, focusing on such outcomes as all-cause mortality, recurrent MI and target vessel revascularization.

VIDEO: Vaccines boosted survival among STEMI heart attack patients with COVID-19

Santiago Garcia, MD, lead author of the study and director of the structural heart program at The Christ Hospital in Cincinnati, Ohio, presented new data from the North American COVID-19 STEMI (NACMI) registry at ACC.22. Severity of heart attacks were reduced in vaccinated patients, with zero deaths in vaccinated patients in 2021.

Researchers are using an intra-atrial shunt to lower pressures between the upper chambers of the heart to relieve symptoms in HFpEF heart failure patients. The novel Noya device uses an RF ablation to cut a hole into the septum and then enlarge it using a stent that can then be removed from the body after the procedure. 

Researchers share first human data on new interventional shunt procedure for HFpEF

The first-in-man study, completed by a team of cardiologists in China, included 10 patients presenting with HFpEF.

The catheter was co-developed with Biosense Webster to perform EP procedures. It also can be used in place of TEE in structural heart procedures to eliminate the need for an interventional echocardiography.  #ACC22

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."
