Vascular & Endovascular

This channel includes news on non-coronary vascular disease and therapies. These include peripheral artery disease (PAD), abdominal and thoracic aortic aneurysm (AAA and TAA), aortic dissection, pulmonary embolism (PE), critical limb ischemia (CLI), carotid artery and stroke interventions, venous interventions, deep vein thrombosis (DVT), and interventional radiology therapies. The focus on most of these therapies is minimally invasive, catheter-based procedures performed in a cath lab.

$Performing CT-derived fractional flow reserve (CT-FFR) before transcatheter aortic valve replacement (TAVR) improves the accuracy of coronary CT angiography (CCTA) and helps limit unneeded invasive coronary angiography (ICA), according to a new study published in JACC: Cardiovascular Interventions.

AI-based CAD assessments dramatically improve vascular surgery outcomes
PAD patients evaluated with HeartFlow's noninvasive FFR_CTAnalysis technology prior to surgery experienced much better outcomes, including a 63% lower risk of all-cause mortality after five years.
FDA announces new recall of delivery catheters after patient’s death
The recall includes specific lots of five different medical devices used to treat stroke and other neurovascular diseases.
Dual-action thrombectomy device could give cardiologists a new tool for treating acute PE
The new device is believed to be the first of its kind, using both aspiration and mechanical clot disruption to remove blood clots.
TAVR linked to lower stroke risk than SAVR in patients with AS and cardiogenic shock
TAVR is also associated with a lower risk of acute kidney injury in this patient population. In-hospital mortality rates, however, are similar between the two treatment options.
PAD patients face greater risk of death, complications after a heart attack
PAD and CLI patients who show signs of coronary heart disease may benefit from early treatment, according to a new study of nearly 4 million hospitalizations.

Chest X-ray. Using an explainable artificial intelligence (AI) model, researchers were recently able to accomplish highly accurate labeling on large datasets of publicly available chest radiograph X-rays..

New AI model calculates risk of heart attack or stroke using a single X-ray

“This type of screening could be used to identify individuals who would benefit from statin medication but are currently untreated," one specialist said. The full analysis will be presented at RSNA 2022 in Chicago.

$Example of fractional flow reserve (FFR) calculated using AI and assessment of the plaque in the vessel on a CT scan of the coronaries. This new type of FFR-CT was shown as a work-in-progress by the vendor Elucid. It was shown for the first time at AHA 2022.$

Interview with the late-breaking BEST-CLI trial principal investigators Alik Farber from Boston Medical Center, Matthew Menard from Brigham and Women's Hospital, and Ken Rosenfield at Mass General Hospital, at the 2022 American Heart Association (AHA) meeting. The trial looked at endovascular versus bypass surgery in patients with critical limb ischemia (CLI) to see which is better. #AHA22

Predictors of 1-year mortality after TAVR are significantly different among men and women

Atrial fibrillation and peripheral artery disease, for example, are both predictors of mortality among women, but not men.
