CardioDx Inc. is a molecular diagnostics company specializing in cardiovascular genomics. It published an analysis demonstrating that the Corus CAD gene expression score is significantly associated with plaque burden and luminal stenosis. The holds true in symptomatic patients being evaluated for obstructive coronary artery disease (CAD), as measured by CT-angiography. The study, "A Peripheral Blood Gene Expression Score is Associated with Atherosclerotic Plaque Burden and Stenosis by Cardiovascular CT-Angiography," appears online in the journal Atherosclerosis.

A University of Utah-led study for treatment of patients with atrial fibrillation (A-fib) provides strong clinical evidence for the use of 3-D MRI to individualize disease management and improve outcomes. Results of the Delayed-Enhancement MRI Determinant of Successful Radio-frequency Catheter Ablation of Atrial Fibrillation (DECAFF) study will be published in the Journal of the American Medical Association.

Results from several late breaking clinical trials will be presented during the American College of Cardiology (ACC) 2014 annual meeting March 29-31. These will be featured during five late-breaking clinical trial sessions.

Transcatheter Technologies GmbH, a medical device company, is developing a third-generation transcatheter aortic valve implantation (TAVI) system, Trinity. An independent laboratory completed advanced wear testing (AWT) of the company’s Trinity valve prosthesis. AWT of the Trinity heart valve has completed 600 million cycles, or an estimated 15 years of durability testing.
