Adenosine physiology: CFR and IMR
Author(s): Robert Jay Widmer Added: 2 months ago
In this 'Cath Lab Guide to Coronary Reactivity Testing', Dr Robert Jay Widmer (The McKinney Heart Hospital, US) turns the focus to thermodilution-based coronary physiology, employing both intracoronary and intravenous adenosine. He demonstrates step-by-step measurement of resting and hyperaemic transit times, distal coronary pressure, and the calculation of fractional flow reserve (FFR), coronary… View more

ACh Protocol and Spasm Testing
Author(s): Robert Jay Widmer Added: 2 months ago
In this segment of the 'Cath Lab Guide to Coronary Reactivity Testing', Dr Robert Jay Widmer (The McKinney Heart Hospital, US) demonstrates an intracoronary acetylcholine protocol using low-dose (20µg) and higher-dose (100µg) infusions. He outlines preparation of the solution from ophthalmic vials, its dilution, and the technique for slow intra-coronary injection over 1–2 minutes.Dr Widmer… View more

Coronary Reactivity Testing for Non‑Obstructive CAD: Case Overview
Author(s): Robert Jay Widmer Added: 2 months ago
Welcome to the introductory segment of Dr Robert Jay Widmer's 'Cath Lab Guide to Coronary Reactivity Testing in Non‑Obstructive CAD'.Dr Widmer (The McKinney Heart Hospital, US) presents the case of a 25-year-old female endurance runner experiencing exertional, band-like chest pain. Her coronary CTA appears normal, while PET imaging reveals mildly reduced flow confined to the circumflex territory… View more

Exercise Stress Testing: A Useful Rule-Out Tool in Suspected ANOCA/INOCA
Added: 10 months ago Source:  Radcliffe Cardiology
For patients with suspected angina with non-obstructive coronary arteries (ANOCA) or ischaemia with non-obstructive coronary arteries (INOCA), the diagnostic pathway can be challenging. A new study suggests that while exercise electrocardiography stress testing (EST) has limited ability to confirm underlying microvascular disease, its high negative predictive value makes it a valuable tool for… View more
