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 agent calling cath lab patients to help them prepare for treatment

Mount Sinai Hospital in New York is now using AI-powered virtual agents to call some patients before cath lab procedures. The move was designed to help nurses focus more on patient care and reduce their risk of burnout.

Abbott recently announced it is partnering with AtaCor Medical to develop a next-generation extravascular implantable cardioverter defibrillator (EV-ICD) system. AtaCor's investigational extravascular ICD lead will be paired with Abbott's investigational extravascular ICD system.
