case_images: Transesophageal echocardiogram at the midesophageal four chamber view showing rupture of the papillary muscle (red arrow) resulting in protrusion of the tricuspid valve and subvalvular apparatus into the right ventricle, and detached anterior leaflet from the annulus (blue arrow). Significant dilatation of right atrium, with increased pressure as demonstrated by the bowing of the interatrial septum into the left atrium.
