Heart Vision: Use of Stress CMR for Evaluation of Microvascular Dysfunction

 

“Heart Vision” is a CardiaCast podcast series produced by the ACC Cardiovascular Imaging Section Leadership Council. This podcast series tackles topics on emerging multimodality imaging data, trends, practice patterns, disease status and advocacy effort. 

In this episode, Drs. Purvi Parwani and Michael Salerno discuss how stress cardiovascular magnetic resonance (CMR) is transforming the way we understand and diagnose coronary microvascular dysfunction. We will also discuss the noninvasive comparison of the stress CMR with stress positron emission tomography (PET) for evaluation of myocardial perfusion reserve index, its clinical applications and practical usage. Dr. Salerno will shed light on how this innovative imaging technique is offering new insights into the pathophysiology of the microvasculature, guiding the diagnosis, and ultimately improving patient outcomes through the correct diagnosis.
