Providence Hospital Carotid Artery Stenting Data compares Favorably with Large Scale Studies

A study by heart care experts at Providence Hospital provides further evidence that with adequate patient volumes, qualified operators and ancillary staff, carotid artery stenting is as safe and effective as a surgical procedure that’s used to open up clogged arteries in the neck in high-risk patients. The study was published recently in the Journal of Invasive Cardiology.

The study examined Providence Hospital’s carotid artery stenting protocol and compared the results with two major studies, the CREST and SAPPHIRE trials. Both of those studies found that stenting and endarterectomy, a surgical procedure whereby a surgeon make an incision in the neck and opens the artery and removes the plaque, were comparable.

Carotid endarterectomy has proven to be a safe and effective procedure for reducing the risk of stroke in patients with plaque build-up in their carotid arteries, a condition known as carotid artery atherosclerosis. The evolution of less invasive carotid artery stenting has made this a viable alternative to carotid endarterectomy in appropriate patient populations.

For the Providence trial, the records of 271 consecutive high-risk patients undergoing carotid artery stenting between January 2005 and December 2011 were reviewed. The study found that 259 patients (95.6 percent) had a successful intervention.

“Our findings indicate that our institution has been able to safely and effectively introduce and carry out carotid stenting as a substitute to carotid endarterectomy in patients that are at high risk for surgery with results comparable to those published in large-scale clinical trials”, says Ghassan Dalloul, M.D., cardiology fellow at Providence Hospital and the study’s lead author.

Dr. Dalloul says further studies are needed to verify whether these results can be generalized to other community hospitals, as well as to refine qualification criteria for performing physicians. Furthermore, the applicability of these results to normal-risk patients is currently being investigated.

Providence Hospital is a member of the St. John Providence Health System Heart & Vascular Care Network, a leading provider of heart care in Michigan. For 11 years, Providence has been ranked as one of top hospitals in the United States for heart care, according to an independent national study conducted by Truven Health Analytics, formerly the health care business of Thomson Reuters. Providence is also recognized as Blue Distinction Centers for Cardiac Care by Blue Cross Blue Shield of Michigan.
