Abstract:Central and regional coronary haemodynamics were studied in a patient with a left anterior descending artery (LAD) graft and angiographically visible collaterals from a normal right coronary artery. A three-thermistor thermodilution catheter was used for measuring total coronary sinus blood flow and great cardiac venous blood flow, the latter being a good representative of blood flow through the LAD. Enflurane-nitrous oxide anaesthesia induced marked coronary vasodilatation and redistribution of blood flow fro… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
