Predictors of Variability in Coronary Flow Reserve and Microvascular Resistance Measurement Using the Bolus Thermodilution Technique

Jason Galo, Aziz Maksoud, Samit Shah, Olga Toleva et autres

BACKGROUND: Bolus thermodilution is the most commonly used invasive assessment for coronary microvascular dysfunction (CMD). However, variability in thermodilution transit time measurements (TTM) affects calculated Coronary Flow Reserve (CFR) and Index of Microvascular Resistance (IMR) values. This study determined variables associated with …

Multicenter Prospective Assessment of Coronary Microvascular Dysfunction

Brian A. Bergmark, Samit Shah, Olga Toleva, Aziz Maksoud et autres

BACKGROUND: Coronary microvascular dysfunction (CMD) and vasospastic angina (VSA) are common, yet underdiagnosed. Existing studies of invasive CMD/VSA assessment have specified patient selection and procedural technique, with little known about testing use in real-world practice. OBJECTIVES: The purpose of the study was …

Investigating real‐world impact of optical coherence tomography workflow‐guided coronary interventions: Design and rationale of the LightLab Clinical Initiative

Jana Buccola, Jennifer Meinen, Joia Spinelli, Michael Hammerstone et autres

OBJECTIVE: The LightLab Clinical Initiative was designed to examine adoption of optical coherence tomography (OCT) imaging during routine percutaneous coronary intervention (PCI) practice, and enable identification and reduction of barriers to broader adoption of intracoronary imaging in real-world practice. BACKGROUND: Intracoronary imaging …
