Anatomy and physiology of coronary blood flow
Regional myocardial blood flow can now be measured noninvasively in units of milliliters blood per minute per gram myocardium. These noninvasive measurements are not confined to a specific imaging modality but are available with MRI, CT, and PET, although, thus far, most investigations of the coronary circulation in humans have employed PET flow measurements. Flow estimates with these different...
متن کامل[Coronary angiography: beyond coronary anatomy].
Although technical advances enable normal epicardial coronary artery blood flow to be restored in most patients suffering myocardial infarction, restoration of blood flow is not always followed by improved myocardial perfusion. Recently, therefore, interest in the assessment of myocardial perfusion has grown, and a number of different assessment methods are available. The aim of this article wa...
متن کاملCoronary Anatomy and Anomalies
AND ANOMALIES The right coronary artery (RCA) arises from the right coronary sinus and runs in the right AV groove (Fig. 5-1). Generally, the conus artery and the sinoatrial artery arise from the RCA. In approximately 85% of individuals, the posterior descending coronary artery arises from the RCA (defined as a right dominant coronary circulation). The left main coronary artery arises from the ...
متن کاملCoronary Artery Anatomy
It has previously been reported that the length of the left main coronary artery is short in patients with left bundle branch block (LBBB) and that an unexpectedly large number of LBBB patients had dominant left coronary arterial distribution. The present coronary arteriographic study of 13 patients with LBBB revealed a mean length of the left main coronary artery (+ 1 SD) of 10.9 + 6.0 mm, a m...
متن کاملIschemia-based Coronary Revascularization: Beyond Anatomy and Fractional Flow Reserve
Treatment strategies for patients with coronary artery disease (CAD) should be based on objective evidence of inducible ischemia in the subtended myocardium to improve clinical outcomes, symptoms, and cost-effectiveness. Fractional flow reserve (FFR) is the most verified index to-date for invasively evaluating lesion-specific myocardial ischemia. Favorable results from large clinical trials tha...
