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.

To eat or not to eat: Is fasting still necessary before heart procedures?
As one may expect, patient satisfaction was considerably higher for individuals who did not have to fast for a minimum of six hours prior to treatment. There were no other significant differences.
Pulmonary embolism thrombectomy use increases by more than 700%
Medicare claims submitted between 2017 and 2022 showed a 712% increase in thrombectomy for pulmonary embolism (PE) and a 137% increase in thrombectomy for deep vein thrombosis (DVT).
Private equity-backed Medline files for IPO
The company, founded in 1966, has been providing supplies to cardiac surgery suites and cath labs for decades.
Key takeaways for interventional cardiology from TCT 2025
B. Hadley Wilson, MD, talked to Cardiovascular Business about several standout late-breaking clinical trials presented at TCT 2025. Topics of those trials included drug-coated balloons, TAVR valve durability, pulmonary embolism treatments and much more.
FDA clears new AI-enabled coronary plaque analysis software
Circle Cardiovascular Imaging, a Canadian medtech company, received the key approval for its cvi42 | Plaque platform.

QFR tops coronary angiography in calculating FFR, detecting stenosis

Quantitative flow ratio (QFR) outperformed coronary angiography in calculating fractional flow reserve (FFR), a measurement key to determining heart blockages, according to a study in the Journal of the American Heart Association.

FDA clears ultrasound tool for IV catheter insertion

EchoNous, the Seattle-based medical tool provider, recently received FDA clearance for the its ultrasound-based tool designed for nurses to improve peripheral IV (PIV) catheter placements.

QFR method could expand access to physiological stenosis assessment

Quantitative flow ratio (QFR) allows for the functional assessment of stenosis on par with fractional flow reserve (FFR) but doesn’t require a guidewire, an international group of researchers reported in the Journal of the American Heart Association.

Myocardial delayed enhancement CT rivals MRI for detecting scar tissue in heart failure patients

Myocardial delayed enhancement (MDE) CT rivaled late gadolinium enhanced (LGE) MRI in the detection and classification of myocardial scar in patients with heart failure, according to a recent Radiology study. The results may help identify features of chronic heart failure.

Wearable ECG device increases AFib diagnoses

Individuals at high risk for atrial fibrillation (AFib) who utilized a home-based wearable electrocardiogram (ECG) patch had a higher rate of AFib diagnosis after four months compared to delayed monitoring.

Informatics approach improves workflow, patient care in IVC filter

Patients with retrievable inferior vena cava (IVC) filters used to prevent venous thromboembolisms face increased complication risks the longer their device remains in the body. Researchers created an informatics tool to address the issue.

$21M MRI suite opens in Western Australia

Jointly funded by the federal and Western Australia (WA) governments, a $21 million state-of-the-art MRI suite for patients seeking neurosurgery recently opened in Perth, Australia, according to a July 6 article in The Australian.

Cardiac MRI, angiography produce similar downstream event rates

Patients with stable coronary artery disease (CAD) who were evaluated with either cardiac magnetic resonance (CMR) or conventional angiography showed similar rates of myocardial infarction and death at one and three years of follow-up, according to a study published in JACC: Cardiovascular Imaging.
