Overview

Chronic Total Occlusion

Chronic total occlusion (CTO) is a condition in which an artery supplying blood to the heart has been completely blocked for at least three months. It's caused by a buildup of plaque (fat, calcium and other substances) on the artery walls. Up to 25 percent of people with coronary artery disease have CTOs.

UCSF is renowned for its heart care programs, and our highly trained experts are experienced in both traditional surgical procedures and minimally invasive techniques for safely and effectively opening blocked arteries. Our team includes cardiologists, interventional cardiologists, surgeons and imaging specialists, and they collaborate closely to thoroughly evaluate each patient and develop the best treatment plan for that individual.
