Abstract: An imaging element characterizes tissue morphology by analyzing perfusion patterns of a contrast media in tissue visualized by the imaging element, to identify infarcted tissue. In a preferred implementation, a catheter tube (12) introduced into a heart region carries the imaging element (34), as well as a support structure (20) spaced from the imaging element, which contracts endocardial tissues. The imaging element is moved as the imaging element visualizes tissue. A selected electrical event is sensed in surrounding myocardial tissue which regulates movement of the imaging element. The support element stabilizes the moving imaging element as it visualizes tissue, providing resistance to dislodgment or disorientation despite the presence of dynamic forces.
