DOI: 10.1002/ccd.30244
Abstract: Microvascular resistance reserve (MRR) as derived from continuous intracoronary thermodilution specifically quantifies microvasculature function. As originally described, the technique necessitates reinstrumentation of the artery and manual reprogramming of the infusion pump when performing resting and… read more here.

DOI: 10.1007/s12471-017-0982-3
Abstract: Coronary angiography is still the gold standard in the diagnosis of coronary artery disease, although its limitations in the assessment of haemodynamic severity of epicardial stenosis are widely recognised [1, 2]. In the 1990s, these… read more here.

DOI: 10.1016/j.jacc.2018.08.2126
Abstract: 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… read more here.

DOI: 10.14814/phy2.15503
Abstract: The assessment of hyperemic microvascular resistance (HMR) may be dependent on the assessment location in the coronary artery and the amount of partial myocardial mass (PMM) distal to the assessment locations. The aim of this… read more here.

DOI: 10.4103/0028-3886.344637
Abstract: Background and Purpose: Leukoaraiosis is thought to be related to long-standing microvascular ischemia. The pathogenic mechanisms and hemodynamic changes could be different for periventricular and deep white matter leukoaraiosis. In this cross-sectional study, we examined… read more here.
