Application of coronary gyroscope in intervention of severe coronary calcification
Objective:To investigate the application of coronary gyroscope in the intervention of severe coronary artery calcification.Methods:The general data of 85 patients with severe coronary artery disease undergoing interventional therapy were retrospectively analyzed,and the pretreatment effect of cutting balloon and coronary gyroscope was explored,and the application value of coronary gyroscope was analyzed.Results:In the control group,the lumen diameter and lumen area of the left main trunk,anterior descending branch opening and rotatory branch opening were smaller,and the calcification distribution Angle of the former was smaller(P<0.05).In the control group,the number of pre-treated balloons,the amount of contrast agent,the exposure time was longer,and the utilization rate of β-blocker was higher(P<0.05).Conclusion:In the interventional treatment of severe coronary artery calcification,the application of coronary gyroscope can reduce the amount of contrast agent,and improve the lumen diameter of target vessels under reduced frequency and low pressure.
