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.
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.
This represents the second significant deal US Heart and Vascular has announced in the last month. The first was a partnership with an established Dallas-based cardiology practice.
American Vascular Associates believes the new investments from Petra Capital Partners and Canopy Capital Partners should help it keep up with the rising demand of outpatient treatment options.
The doctor received two years’ probation for assaulting and threatening to kill his wife. His wife also sued him over this abuse, with the courts ruling that she was owed more than $600,000.
Researchers examined 10-year follow-up data from approximately 400 EVAR patients, sharing their findings at the 2023 Charing Cross Symposium in London.
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.
Laser speckle imaging captures details of blood vessels in a beating donor transplant heart outside the body for viability evaluation. Image from Plyer et al., doi 10.1117/1.JBO.28.4.046007
A new laser imaging technology may be able to determine which donor hearts are viable for transplant and which will result in poor outcomes, without the need for coronary angiography or use of contrast agents that can damage an explanted heart.
Example of interventional echocardiography TEE imaging superimposed on live fluoro during a transseptal puncture for a MitraClip procedure.
The American Society of Echocardiography (ASE) released a new guideline document that outlines uniform training standards for interventional sonographers guiding structural heart procedures.
