Color kinesis-dobutamine stress echocardiography pinpoints coronary artery disease

Abstract

Background/Aim: Dobutamine stress echocardiography (DSE) can identify significant coronary artery disease (CAD) and where it is localized. However, determining endocardial borders with poor echocardiographic views may create unsatisfactory results. Color kinesis (CK) shows endocardial movement with color, and allows easier and more objective evaluation of ventricular wall motion. In this study, our aim was to evaluate the role of CK in determining CAD localization during DSE. Methods: The study group consists of patients whose CAD diagnosis was confirmed with coronary angiography (CA). Patients with atrial fibrillation (A-Fib), left bundle branch block, poor echocardiography image quality, left ventricular (LV) ejection fraction 0.05, 95% CI). Conclusion: Our study showed that CK allows for rapid, objective, and automatic evaluation of segmental wall motion. In addition, CK-DSE is consistent with CA results.
