18+ years
Phase:
NA
Brief Summary
This study will evaluate the changes in myocardial microcirculatory parameters of the collateral donor artery after recanalization of coronary artery chronic total occlusion.
Detailed 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, functio...
