title: Aortic regurgitation and coronary microfistulae: double jeopardy causing myonecrosis.
abstract: We describe a 3-case series of patients with a rare combination of mild-to-moderate aortic regurgitation and coronary microfistulae but nonobstructed epicardial coronary arteries who presented with symptoms of unstable angina and had confirmed myonecrosis. A plausible pathophysiological mechanism for this phenomenon and its clinical implication are discussed.
