Clinical Trial Summary

This study will evaluate the changes in myocardial microcirculatory parameters of the collateral donor artery after recanalization of coronary artery chronic total occlusion.

Description:

This study will include patients with chronic total occlusion (CTO) of one coronary artery who will undergo the recanalization of the CTO. Before the procedure, myocardial viability, ischemia, functional parameters of the collateral donor blood vessels, echocardiography, and quality of life will be assessed. After the recanalization, these parameters will be assessed again 24h and 6 months after the procedure.
