[Chronic coronary artery occlusion: questions from the cardiologist and surgeon, answers from the radiologist].

The main issue with chronic coronary artery occlusion relates to optimal treatment and cross sectional imaging is a valuable source of information. Cardiac MR imaging can identify candidates to revascularization by demonstrating viable myocardium. Coronary CTA allows evaluation of the entire coronary system and detection of factors predicting the success of revascularization, either percutaneous (angioplasty) or surgical.
