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.

TAVR costs vary significantly from one hospital to the next

According to a new study of more than 119,000 hospitalizations, the costs associated with TAVR are far from consistent. 

SCAI President Sunil Rao explains what he saw as the top 5 interventional studies at ACC23. #SCAI #ACC #ACC23

5 studies that could make a big impact on interventional cardiology

SCAI President Sunil Rao, MD, spoke with us about some of the key interventional cardiology studies presented at ACC.23 in New Orleans.

Transradial access should be ‘default strategy’ for PCI, new study confirms

Researchers explored data from nearly 25,000 PCI procedures, tracking the outcomes of patients treated with transradial access and transfemoral access. 

AI predicts mortality risk based on ECG results with 85% accuracy

The model estimated mortality risk for more than 244,000 patients in Alberta, Canada, who had an ECG taken after a related health incident. 

Images from the consensus document showing the proper left atrial appendage (LAA) sizing assessment for a transcatheter occluder device using transesophageal echo (TEE). Sizing and evaluation for pre-existing thrombus in the LAA also can be performed using cardiac CT.

SCAI and HRS release expert consensus on transcatheter left atrial appendage occlusion

One of the new recommendations is to conduct baseline imaging with TEE or cardiac CT.

Echocardiography expert Patricia A. Pellikka, MD, discussed the trend of increasing artificial intelligence (AI) integration in cardiac ultrasound with Cardiovascular Business at American College of Cardiology (ACC) 2023 meeting.

AI's growing impact on echocardiography

Cardiology has the second largest number of FDA-cleared AI algorithms, and many of them are for cardiac ultrasound. Echocardiography expert Patricia A. Pellikka, MD, discusses this trend and how AI is helping improve echo.

Atul Verma explains thne results of the PULSE-AF trial at ACC23.

Pulsed-field ablation could be the next big EP technology trend

Atul Verma, MD, director of cardiology at McGill University Health Centre in Montreal, explained why the late-breaking PULSED-AF trial data on Medtronic’s pulsed-field ablation technology is so important for cardiologists. 

Example of an FFR-angio image-derived hemodynamic flow model performed tableside in the cath lab reconstructed using three different C-arm contract image acquisitions. This technology from CathWorks, which was recently acquired by Medtronic, can eliminate the need for pressure wires and adenosine to assess FFR pressures. These measurements are used to determine the hemodynamic significance of a stenosis and determine if a stent is necessary or if a patient can be treated medically.
