Echocardiography

Cardiac ultrasound uses reflected sound waves (echos) to create images of anatomy inside the body. Echocardiograms are the primary cardiac imaging modality used to assess the heart and diagnose or track cardiac issues. Echo is the gold standard imaging modality to assess the heart, particularly with calculating left ventricular ejection fraction (LVEF), which is a measure of cardiac output. In addition to noninvasive standard transthoracic echo (TTE), invasive transesophgeal echo (TEE) is also used when clearer, more detailed imaging of the heart is needed. Both 3D and 4D echo echo systems are rapidly gaining wider adoption and enable new types of assessments, especially in the structural heart space and in transcatheter procedural guidance.

New multi-society recommendations highlight role of non-invasive imaging in evaluating coronary artery disease

A new, multi-society document, "Non-Invasive Imaging in Coronary Syndromes," focuses on how multiple imaging techniques can evaluate different aspects of coronary artery disease (CAD), all without the need for invasive angiograms.

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

What does radiology have to do with climate change?

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."
