Myocardial Work: A Modern Tool to Detect Possible Compensation Mechanism of Deformation in Acute Myocarditis with Preserved Left Ventricular Function.

The architecture of the myocardial fibers defines the different components of left ventricular (LV) contraction. Subendocardial layers are primarily responsible for longitudinal LV deformation and subepicardial layers for circumferential LV deformation. The specific analysis of the different components of LV deformation by echocardiography might offer new diagnostic options in patients with acute myocarditis (?IM). This case report focuses on specific pathological findings of regional LV deformation in a patient with IM and preserved LV systolic function.
