NON INVASIVE DETECTION OF ACCELERATED STENOTIC FLOW IN THE ENTIRE LEFT ANTERIOR DESCENDING CORONARY ARTERY PROVIDES INSIGHT INTO THE CAUSES OF IMPAIRED CORONARY FLOW RESERVE: A STUDY CONDUCTED WITH ENHANCED TRANSTHORACIC CONVERGENT COLOR DOPPLER ECHOCARDIOGRAPHY

Non-invasive flow velocity assessment in the entire LAD is highly feasible and reliable in detecting significant coronary stenosis, providing essential information for distinguishing epicardial coronary stenosis from other microvascular causes of CFR reduction
