Medical imaging and visualization company Medivis announced the launch of AnatomyX, its augmented reality (AR) platform for anatomy education. Currently enabled on Microsoft's HoloLens AR technology and Magic Leap's spatial computing device, Magic Leap One, AnatomyX offers any member of a large university or medical institution an enterprise-grade learning platform for the study of human anatomy, physiology and pathology.

April 2, 2019 — A Swedish review of out-of-hospital cardiac arrest data shows rates of bystander cardiopulmonary resuscitation (CPR) nearly doubled, and compression-only (or Hands-Only CPR) increased six-fold over an 18-year period.

How to reduce radiation dose in cardiac CT.

April 1, 2019 — Here is a checklist of dose-sparing practices for coronary computed tomography angiography (CCTA) imaging. This list was included in a new 2018 consensus document to guide the optimal use of ionizing radiation in cardiovascular imaging.[1] 
 

AIMed Radiology - Artificial Intelligence in Medicine

The 2019 AIMed Radiology conference in June in Chicago is aimed at those interested in the use of artificial intelligence (AI) and deep learning in advanced medical imaging. The conference also allows attendees to experience the future of radiology using augmented and virtual reality and to understand the future of medical education and training with AI. 

The conference is June 18-19, 2019, at the Ritz-Carlton Chicago. The event is expected to draw 1,800 attendees, 350 speakers and about 1,500 companies, including start-ups and some of the key players bringing AI into Healthcare.

The top cardiac technology news item in March was the FDA clearing the MitraClip for use in heart failure patients with functional mitral regurgitation based on the very positive results of the COAPT Trial.

April 1, 2019 — Here is the list of the most popular content on the Diagnostic and Interventional Cardiology (DAIC) magazine website from the month of March 2019. This is based on the website’s 276,315 pageviews for the month:
 
 

The cardiovascular benefits of the diabetes drug dapagliflozin extend across a wide spectrum of patients and are especially pronounced in those with reduced ejection fraction, according to new research. The findings were presented at the American College of Cardiology’s (ACC) 68th Annual Scientific Session, March 16-18 in New Orleans.

A research team from Imperial College London believes a new software could speed up the diagnosis and treatment of patients with faulty cardiac rhythm devices in an emergency setting. The software has been able to identify the make and model of different devices, such as pacemakers and defibrillators, within seconds.

Taking a high dose of icosapent ethyl significantly reduces the occurrence of first, subsequent and total ischemic events, including heart attacks, strokes and related deaths, among people at high cardiovascular risk despite already being on statin therapy. These findings came from research presented at the American College of Cardiology’s (ACC) 68th Annual Scientific Session, March 16-18 in New Orleans.

All major vendors offering advanced visualization software now offer structural heart planning. This is an example of GE Healthcare's Valve Assist software being used to determine the best location of a transseptal puncture to deliver a left atrial appendage (LAA) occluder.
An angiographic view of a Medtronic Corevalve being deployed. Fluoroscopy does not show soft tissue, so CT overlays showing anatomical landmarks and TEE are used for procedural guidance.
Part of the pre-procedural TAVR workup is using CT images to assess access routes to make sure the larger sized devices can be delivered to the heart using the femoral access route, as shown here. Measurements are taken along the femoral arteries and aorta to check clearances. If the route is not clear, some patients may still be able to use the transapical access route with the help of the cardiac surgeon on the heart team.
Using either a CT scan or rotational angiography acquisition in the cath lab that is fused with the live angiography, anatomical outlines can be added to aid in TAVR catheter and device delivery and to highlight anatomical landing zones and orientation for the valve.

Structural heart interventions represent one of the fastest growing segments of cardiology, as the number of devices to address valvular and nonvalvular heart disease continues to expand rapidly. Imaging is a critical component for all aspects of structural heart treatment — from disease assessment and patient selection, to device selection and sizing as well as procedural risk prediction.
