We present a case with right coronary ostium agenesis with anomalous origin of the right coronary artery from the left circumflex artery, which caused a non-ST elevation coronary syndrome. A review of the literature indicates this to be an extremely rare case.

## Abstract ## Purpose To determine the feasibility of T~2~βweighted BOLD imaging for estimating regional myocardial oxygen extraction fraction (OEF) and approximating perfusion reserve (MPR) simultaneously in a canine model with moderate coronary artery stenosis. ## Materials and Methods Eight
Some patients with anginal chest pain and normal coronary arteries exhibit a paradoxical increase in coronary flow velocity after termination of acetylcholine infusion. The aim of this study was to investigate whether this paradoxical increase in the flow velocity is associated with the impaired mic
