Carotid pulse wave velocity (PVW) measured with ultrafast ultrasound at the end of systole (PWV-ES) may be a better biomarker of carotid stiffness in diabetic patients than PWV measured at the beginning of systole, according to a new study.

With the development of a new three-dimensional (3D) printing workflow, researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University in Boston may help cardiologists produce more proficient implantable heart valves and determine how different sized valves interact for each patient before surgical intervention for aortic valve replacement, according to a Dec. 10 report by the 3D Printing Media Network.

The FDA has granted a breakthrough device designation for an artificial intelligence (AI) pattern recognition software being developed by Bayer and Merck & Co. in New Jersey that can identify signs of chronic thromboembolic pulmonary hypertension (CTEPH)—a rare form of hypertension—in CT pulmonary angiography (CTPA) scans, according to a Dec. 3 press release.

“We’d better make some rules because otherwise, you can have willy-nilly 3D printing...you can 3D print off your iPhone if you have the right hook-ups, right? But we don’t want that. We want to do really high-quality work," said Frank J. Rybicki, MD, PhD, at the American Heart Association’s 2018 Scientific Sessions in Chicago according to a report by Cardiovascular Business.

Performing CT analysis prior to percutaneous pulmonary valve implantation (PPVI) in patients with congenital heart disease (CHD) may assist physicians in detecting those who are most at-risk for coronary artery compression during the operation.

The study will determine whether CMAs can obtain echocardiograms that, when reviewed by cardiologists, will detect more patients with cardiac disease compared to a standard physical examination with an electrocardiogram (ECG) in a primary care setting, according to a Northwestern University press release.

Updated cholesterol guidelines from the American Heart Association and the American College of Cardiology suggest a more personalized approach to stroke risk assessment and address criticisms of five-year-old recommendations, according to CNN. But one new recommendation has generated pushback.

Last year, more than 56,000 angina patients across the U.K. were denied life-saving CT heart scans due to the continuing shortage of radiologists and scanners, according to data released Nov. 8 by the Royal College of Radiologists (RCR) and the British Society of Cardiovascular Imaging (BSCI), published in The BMJ.

Researchers from the Netherlands demonstrated, in a study published Oct. 30 in Radiology, that four-dimensional (4D) flow MRI with automated cardiac valve tracking reduces analysis time and improves reliability of valvular flow quantification compared to manual valve tracking in patients with congenital heart disease.

A patent filed in 2014 by Apple Inc. for a new method to print three-dimensional (3D) models using triangular tessellation was recently approved by the U.S. Patent and Trademark Office on Tuesday, Oct. 23, according to a report by TechCrunch.com.

Using MRI technology, researchers from Washington University in St. Louis have found the cerebellum—a part of the brain long ignored by scientists—is more involved in higher-order thinking than previously thought, according to a report published Oct. 25 by NPR.

Kinetic imaging in x-ray angiography outperforms digital subtraction angiography at providing better image quality and reducing radiation exposure for improved viewing of small blood vessels, according to research published online Oct. 16 in Radiology.
