Reversible Myocarditis after Black Widow Spider Envenomation
Figure 2
(a) Echocardiographically parasternal long axis depicted improvement of ventricle function. First echocardiogram obtained four days after admission showed LVEF of 48% (calculated by Simpson method). Hypokinesis of the septum and parietal wall of the left ventricle. (b) Second echocardiogram taken 24 days after BWS envenomation depicted good evolution of mitral regurgitation becomes grade I. LVEF was 50%.
