Christopher Allen, M.D., is the first physician in the St. Louis area to use Medtronic’s IN.PACT Admiral, a drug-coated balloon used to treat peripheral artery disease in the upper leg. The newly approved treatment was used to treat a patient at St. Anthony’s on February 3, 2015, the first day it was available. The treatment expands the services available at the new Heart & Vascular Institute at St. Anthony’s.

Peripheral artery disease (PAD) is a narrowing of the arteries that can cause pain, limit your ability to walk or balance, cause poor circulation, and create open sores that are slow to heal. People with PAD also have a four to five times greater risk of suffering a heart attack or stroke.

In this first procedure performed by Dr. Allen, a cardiologist with St. Anthony’s Heart Specialty Associates, the patient, Jackie Gallino of South County, had developed an ulcer in her leg because of a lack of blood flow caused by a significant blockage of plaque at an inflexion point.

"We chose Jackie for this new treatment because of the location of the blockage," said Dr. Allen. “A regular stent would not have worked well for her in reopening this artery."

Research by Medtronic shows that use of its new drug-coated balloon provides the best clinical outcomes reported for PAD in the legs. These improved outcomes can reduce the need for repeat procedures commonly associated with other interventional therapies for PAD.

"Not only does this balloon reopen the affected artery, it delivers the drug paclitaxel, which is designed to keep the artery from narrowing again by working to prevent scar tissue from forming," said Dr. Allen.
