TCT-874 Coronary Microvascular Function During STEMI: Real Time Absolute Dynamic Microvascular Resistance in an Experimental Porcine Model Using Controlled Flow Infusion

Coronary microvascular dysfunction during STEMI is poorly understood. Dynamic microvascular resistance (dMVR) can now be measured precisely and in real time using controlled coronary flow infusion, a simple catheter-based technique. This study characterized infarct zone microvascular dysfunction
