Treatments for arterial blockage due to coronary artery disease vary in terms of invasiveness and can take from 30 minutes to six hours, according to WebMD. The condition is treatable by balloon angioplasty, stent placement and coronary artery bypass surgery.
Balloon angioplasties are used to dilate a restricted artery area using a catheter with an inflatable tip. During a balloon angioplasty, stents can be applied to the restricted artery. Stents are small, expandable tubes, usually made of metal mesh. Angioplasty with stenting can take as little as 30 minutes to three hours, according to HeartSite.com. Coronary artery bypass surgery uses a healthy artery section to bypass arterial blockage, and generally takes three to six hours, according to Mayo Clinic.
