Occlusion risk appears underappreciated
The risk of radial artery occlusion might be underappreciated. According to data cited by Dr. Hammami, only about half of interventionalists in the United States and fewer than 10% outside of the United States routinely assess radial artery patency in conjunction with radial-access PCI. The data from this trial suggest that the risk can be substantially reduced, particularly in high-risk patients, with anticoagulant therapy.

Agreeing that this is a potentially avoidable complication, Roxanna Mehran, MD, director of interventional cardiovascular research and clinical trials, Icahn School of Medicine at Mount Sinai, New York, called the RIVARAD study “a clinically meaningful trial,” and valuable for identifying risk factors as well as for showing a treatment effect and acceptable safety from a short course of a factor Xa inhibitor.
“This is very important work,” said Dr. Mehran, who praised the quality of the study and the contribution it makes for considering how and when prophylaxis is needed.
Dr. Hammami reported no potential conflicts of interest. Dr. Mehran has financial relationships with more than 25 pharmaceutical companies but none with the sponsor of this trial, which was funded by Philadelphia Pharma, a drug company based in Tunisia.
