Coronary flow characteristics of Loeffler’s endocarditis. Myocardial perfusion at rest (a) and in hyperaemia state (b). At rest, a small lack of endocardial perfusion is present (arrows, a). The endocardial intensity-time curve shows a slower contrast agent uptake in comparison to the epicardial curve still reaching epicardial intensity at the end of the sequence. This phenomenon was intensified in regadenoson stress protocol (arrows, b). Endocardial intensity-time curve did not reach epicardial values throughout the sequence indicating impaired coronary microcirculation
