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.

X-ray photon trajectory during the simulation phantom study from the side and top views. Due to scattering of the X-rays when they hit the lower end of the patient bed, exposure in mainly to the lower body of the interventional echocardiographer performing transesophageal echocardiography. The green lines are the scattered photon trajectories calculated by Monte Carlo simulation in the study.

Radiation exposure in the cath lab: Tracking the impact on interventional echocardiographers

Researchers found that echocardiographers in the cath lab are exposed to high doses of radiation on the right half of their body, especially the waist and lower body.

Understanding INOCA and MINOCA epidemiology

Janet Wei, MD, associate medical director of the Biomedical Imaging Research Institute, and co-director of the stress echocardiography lab at Cedars-Sinai Hospital, explains the current information on the INOCA and MINOCA.

New ASE guideline outlines training standards for interventional echocardiography

The American Society of Echocardiography (ASE) released a new guideline document that outlines uniform training standards for interventional sonographers guiding structural heart procedures.

Raj Makkar, MD, Cedars-Sinai’s vice president of Cardiovascular Innovation and Intervention and the Stephen R. Corday, MD, Chair in Interventional Cardiology, explains the ACC 2023 results on the safety and efficacy of transcatheter edge-to-edge mitral valve repair in degenerative mitral regurgitation (MR) study. It was a review of data is from the STS/ACC TVT Registry that was presented at the American College of Cardiology (ACC) 2023 meeting.

New data on real-world TEER outcomes in patients with degenerative MR

TEER can significantly improve a patient's chances of survival, new findings confirm.

COVID-19 linked to elevated risk of life-threatening arrhythmia

Patients with severe COVID-19 cases that required ventilation were 16 times more likely to develop ventricular tachycardia within six months, researchers found.
