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.

Outcome

Type Measure Description Time frame Safety issue
Primary Coronary flow reserve Change in coronary flow reserve of the collateral donor vessel (after PCI as compared to values before PCI) will be regarded as primary outcome measure six months
Secondary Coronary flow velocity reserve Correlation of coronary flow velocity reserve change of the collateral donor vessel (after PCI as compared to values before PCI) with viability measured by the percentage of viable myocardium on Single Photon Emission Computed Tomography (SPECT) of myocardial perfusion. six months
Secondary Wall Motion Score Index (WMSI) Relation of coronary flow velocity reserve change with wall motion score index on stres-echocardyography test where the wall motion segment abnormalities will be graded as such: 1 - normokinesis, 2 - hypokinesis, 3- akinesis and 4 dyskinesis, and the higher values indicates worse outcome six months
Secondary Change from Baseline Stable Angina questionnaire (SAQ) at 6 months Relation of coronary flow velocity reserve change with the quality of life measured by 19-item Seattle Angina Questionnaire that assesses angina frequency (with 9 questions where answers range from 1 to 6, the total score ranges from 0 to 100, where the higher value indicates better outcome), angina stability ( with 1 question where answers range from 1 to 6, the total score ranges from 0 to 100, where the higher value indicates better outcome), the angina frequency scale (with 2 questions where answers range from 1 to 5, the total score ranges from 0 to 100, where the higher value indicates better outcome), treatment satisfaction (with 4 questions where answers range from 1 to 6, the total score ranges from 0 to 100, where the higher value indicates better outcome), and disease perception/QoL (with 3 questions where answers range from 1 to 5, the total score ranges from 0 to 100, where the higher value indicates better outcome) six months
