[Dobutamine speckle tracking imaging for evaluation of microvascular dysfunction in a patient with exertion dyspnea]

Abstract

Microcirculatory dysfunction despite the absence of angiographically obvious significant coronary artery disease may potentially generate symptomatic myocardial ischemia; comprehensive assessment both noninvasive and invasive could prove to be of critical interest. We report the case of a 54-year old patient referred for an exertion dyspnea that proved to be caused by both micro and microvascular dysfunction. We present key elements for diagnosis, functional evaluation and management and demonstrate the potential role of speckle tracking imaging in that setting.
