A new part to the traditional angioplasty combines a catheter and low doses of radiation to help open up narrowed blood vessels. It's called intravascular radiotherapy and it's coming up with positive results.
Doctors say the radiation decreases scar tissue growth up to 70 percent. This helps prevent patients from undergoing open-heart surgery and decrease the chances of a heart attack.
The extra step does take an extra 15 to 30 minutes.
Patients who go through radiation angioplasty will spend one night in the hospital.
Most insurance providers cover procedure costs.
