Patients who underwent noninvasive diagnostic testing after evaluation for chest pain in the ED had a lower observed rate of CV death or MI, according to a retrospective cohort study published in the Journal of the American Heart Association.

SAN FRANCISCO — Guidance with OCT led to a lower occurrence of significant angina or the composite of MACE compared with guidance with fractional flow reserve in patients with angiographically intermediate coronary lesions, according to 13-month data from the FORZA trial presented at TCT 2019.

HeartVista announced that it received 510(k) clearance from the FDA for its AI-assisted MRI acquisition software for cardiac exams.

Siemens announced it has acquired Corindus Vascular Robotics, manufacturer of robotic-assisted PCI systems, for $1.1 billion.

SAN FRANCISCO — Among patients who underwent PCI for long lesions, IVUS-based guidance was associated with better outcomes than angiography-based guidance at 5 years, according to new data from the IVUS-XPL trial presented at TCT 2019.

Ventripoint Diagnostics announced its analysis system that works with standard echocardiography machines has been cleared for commercial use by the FDA.

Canon Medical Systems USA announced the FDA granted 501(k) clearance to its image reconstruction technology that uses a deep learning algorithm.

The beneficial effect of a coronary CT angiography-based strategy on clinical outcomes compared with standard care in patients with chest pain was consistent across subgroups, and the benefit chiefly occurs because of preventive treatments given to those with stable CAD, according to new data from the SCOT-HEART study.

SAN FRANCISCO — In a CT substudy of the PARTNER 3 trial of low surgical risk patients who underwent transcatheter or surgical aortic valve replacement, hypoattenuated leaflet thrombosis and reduced leaflet motion were not associated with death, MI and stroke, according to data presented at TCT 2019.

A machine learning network, a form of artificial intelligence, was able to consistently measure left ventricular ejection fraction as well as LV mass in cardiac MRI scans faster, with comparable reliability to experienced clinicians and a significantly shorter training period.
