Angiography‐derived versus invasively‐determined index of microcirculatory resistance in the assessment of coronary microcirculation: A systematic review and meta‐analysis
Sign Up to like & getrecommendations! Published in 2022 at "Catheterization and Cardiovascular Interventions"
DOI: 10.1002/ccd.30174
Abstract: The index of microvascular resistance (IMR) is an established tool to assess the status of coronary microcirculation. However, the need for a pressure wire and hyperemic agents have limited its routine use and have led… read more here.

DOI: 10.1002/ccd.30526
Abstract: Noninvasive methods of estimating invasively measured fractional flow reserve (FFRinvasive) are actively being explored, aiming to avoid the use of an invasive pressure wire and the administration of hyperemia‐inducing drugs. Coronary angiography‐derived FFR (FFRangio) has… read more here.

Comparison of a Fully Angiography‐Derived Versus a Hybrid of Angiography and Pressure‐Wire‐Derived Approach to Assess Coronary Microvascular Resistance: The Oxford Acute Myocardial Infarction Hybrid (OxAMI‐HYBRID) Study
Sign Up to like & getrecommendations! Published in 2024 at "Catheterization and Cardiovascular Interventions"
DOI: 10.1002/ccd.31311
Abstract: Despite growing evidence of its clinical implications, assessment of coronary microvascular dysfunction (CMD) remains limited in routine clinical practice. Hence, there is an increasing interest in angiography‐derived indices to encourage assessment of CMD in the… read more here.

Coronary Angiography‐Derived Murray Law‐Based Quantitative Flow Ratio (μQFR) After De Novo Drug‐Coated Balloon Angioplasty
Sign Up to like & getrecommendations! Published in 2025 at "Catheterization and Cardiovascular Interventions"
DOI: 10.1002/ccd.70150
Abstract: Drug‐coated balloon (DCB) angioplasty has emerged as a stentless alternative for de novo coronary artery disease. However, the prognostic value of post‐procedural angiography‐derived physiology, particularly three‐dimensional (3D) Murray‐law quantitative flow ratio (μQFR), after DCB in… read more here.

The spectrum of angiography‐derived IMR according to morphological and physiological coronary stenosis in patients with suspected myocardial ischemia
Sign Up to like & getrecommendations! Published in 2023 at "Clinical Cardiology"
DOI: 10.1002/clc.23999
Abstract: Coronary microvascular dysfunction is crucial in determining myocardial ischemia; however, the relationship between epicardial coronary diameter stenosis (DS) and the index of microcirculatory resistance (IMR) remains unclear. We sought to explore the distribution of coronary… read more here.
