Chronic Coronary Total Occlusion
The heart is a muscle, and — like any other muscle — it needs oxygen-rich blood.
Chronic coronary total occlusion (CTO) occurs when a buildup of plaque blocks the coronary artery for more than 90 days, starving your heart of oxygen. Left untreated, CTO can cause chest pain, unusual fatigue, and lifestyle restrictions.
The UPMC Heart and Vascular Institute is one of a few centers with the expertise in performing angioplasty to treat CTO.
