Key result
Surgical treatment combining full myocardial revascularization with reconstructive correction of morphofunctional mitral valve changes was performed for acute ischemic mitral regurgitation.
Why the study?
Recent research has shifted the understanding of the role of mitral leaflets from static components in ischemic mitral regurgitation, especially in chronic myocardial ischemia.
Case Report (n=1)
Full myocardial revascularization combined with mitral valve reconstruction may allow for reverse remodeling of leaflets and prevent recurrent ischemic mitral regurgitation.
Chord rupture may cause acute ischemic MR; leaves open whether leaflet dynamics warrant new therapies in chronic ischemia.
Introduction. The evolution of the study of mitral valve ischemic dysfunction influenced by fundamental and experimental research in recent years has led to a change of mitral leaflets role as a static component of the mitral valve in the pathogenesis of ischemic mitral regurgitation especially in the chronic myocardial ischemia. Objective. We report the clinical case of acute ischemic mitral regurgitation as a result of a chord rupture of the PML in a patient with unspecified duration of coronary artery disease without acute coronary syndrome and previous myocardial infarction including all stages of the diagnostic search and the results of surgical treatment. Conclusion. While performing reconstructive correction of the ischemic mitral regurgitation the possibility of reverse remodeling of the leaflets should be considered in case of removal the myocardial ischemia triggering factor. And therefore it is necessary to perform a full and adequate myocardial revascularization that combined with a full correction of all morphofunctional mitral valve changes guarantees the freedom from residual and recurrent mitral regurgitation.
