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.

AI turns low-quality MRI scans into helpful heart images
A team of biomedical engineers, radiologists and cardiologists has developed a new AI model capable of restoring low-quality cardiac MRI scans.
Johnson & Johnson MedTech faces threat of permanent injunction after losing antitrust case
After being ordered to pay $442 million in damages—a ruling the company has said it may appeal—Johnson & Johnson MedTech is now facing the possibility of a permanent injunction that could impact certain business practices. A hearing is scheduled for July.
Cardiologists, radiologists and surgeons share ‘landmark’ document on assessing prosthetic heart valves with CT
RSNA and several other industry societies have shared a new expert consensus document on the significant value of cardiac CT. Echo remains an effective first-line imaging option, the groups wrote, but CT can make a big impact as well.
AMA resolution backs expanded low-dose CT screenings for lung cancer, heart risk
Dana Smetherman, MD, CEO of the American College of Radiology, discusses the policy, which urges for more robust promotion of low-dose CT as a public health tool.
Angiographic catheters recalled due to safety risk
The new Class I recall includes nearly 27,000 devices that could potentially experience a harmful defect during use.

The rapid rise of artificial intelligence (AI) has helped cardiologists, radiologists, nurses and other healthcare providers embrace precision medicine in a way that ensures more heart patients are receiving personalized care.

AI uses imaging results to ID high-risk TAVR patients with speed, accuracy

Researchers developed an advanced AI model capable of extracting measurements from unprocessed CT images in seconds. It then uses those data to evaluate the patient's mortality risk if they underwent TAVR.

Heart Rhythm Socity (HRS) President Kenneth Ellenbogen, MD, explains key electrophysiology (EP) trends at the HRS 2024 meeting. #HRS #HRS24 #HRS2024 #EPeeps

Key trends in electrophysiology include PFA, dual-chamber leadless pacemakers

HRS President Kenneth Ellenbogen, MD, detailed some of the biggest trends in electrophysiology at Heart Rhythm 2024 in Boston.

AI-based coronary plaque assessments 1 step closer to Medicare coverage

According to a new proposal, using AI to evaluate CCTA results and quantify plaque buildup is “reasonable and medically necessary” in certain clinical scenarios.

It’s official: Johnson & Johnson completes $13B Shockwave Medical acquisition

The deal, first announced in April, has been finalized. Shockwave will now operate as a business unit within Johnson & Johnson MedTech, and its common stock is no longer trading on NASDAQ.

Osteosarcopenia linked to much higher risk of death after TAVR—CT screening may prove valuable

Osteosarcopenia, an age-related condition associated with deterioration in the muscles and bones, nearly triples a patient’s risk of dying within one year of undergoing TAVR.

Cardiologist sees ‘tremendous potential’ in new-look PFA system

Updated data on a new PFA system from Kardium found that freedom from atrial arrhythmia after one year was 84.2% for paroxysmal AFib and 80% for persistent AFib.

Cardiologists ID signs of widespread heart disease in ancient mummies

Researchers evaluated vascular samples from more than 200 mummies, presenting their findings in European Heart Journal.

All-in-one PFA system linked to positive safety profile, faster procedures

Devi Nair, MD, director of cardiac electrophysiology with St. Bernard's Heart and Vascular Center, discussed her experience using a new-look Medtronic pulsed field ablation (PFA) system to treat persistent AFib.
