To date, only one third of patients, with stable angina, undergoing coronary angiography demonstrated obstructive coronary artery disease (CAD). Thus, identifying high sensitivity and specificity, low-cost, non invasive tests is crucial. Here we present the case of a patient, at a high risk of CAD, undergoing coronary angiography because of positive exercise test and stress imaging results, with non obstructive coronary artery disease at angiography, confirmed by FFR. Interestingly, 3D speckle tracking, performed before angiography, assessed normal left ventricle deformation, predicting the absence of severe coronary artery lesions.
