Stress-MRI Assessment After Right Coronary Artery CTO Recanalization

Clinical Significance of Stress-MRI Evaluation of Right Coronary Artery Chronic Total Occlusion Recanalization Efficacy in Patients With Coronary Artery Disease.

The hypothesis of this study is that Stress-MRI is a clinically significant method of myocardial perfusion assessment after coronary angioplasty with stenting of right coronary artery (RCA) chronic total occlusion (CTO) is performed.

Inclusion Criteria:

• Stable angina, CCS FC II-IV
• "Right-dominance" coronary circulation according to coronary angiography
• Absence of other significant atherosclerotic coronary lesions (more than 65%)
• High risk of myocardium ischemia according to stress-MRI data (perfusion defect in 2 or more segments in the area of interest)
• Signed, documented informed consent prior to admission to the study

Exclusion Criteria:

• Acute coronary syndrome
• Contraindications for adenosine stress test
• Low and moderate risk of myocardium ischemia according to stress-MRI data (perfusion defect in less than 2 segments in the area of interest)
