Isolated Right Ventricular Noncompaction Cardiomyopathy Causing Pulmonary Embolism

Figures

  Figure 1.. An apical view of the right ventricle. (a) The red circles indicate the deep sinusoidal recesses with the encompassing deep trabecular meshwork. (b) The red circles indicate the recesses and crypts. The white eclipse indicates the marked right ventricular enlargement relative to the left ventricle.

  Figure 2.. Computed tomography scan, pulmonary embolism protocol. (a) The red circle indicates right ventricular dilatation, whereas the red arrow indicates the trabecular meshwork at the right ventricular apex. (b) The red circle indicates a more focused image of the right ventricular enlargement with marked sinusoids amidst the trabecular mesh.

  Figure 3.. Computed tomography scan, pulmonary embolism (PE) protocol. The red circle indicates the left pulmonary artery, which appears visually dilated, and the red arrows indicate the substantial, serpiginous thrombus burden, presumably arising from the isolated right ventricular noncompaction, consistent with a hemodynamically significant, submassive PE.
