Abstract

A patient with a previous lung transplant and aortic valve replacement had progressive dyspnea. He presented with subacute tamponade secondary to a loculated pericardial effusion that caused impaired left ventricular filling and outflow tract obstruction secondary to distortion of the mitral valve apparatus. We demonstrate the imaging features of this presentation. (Level of Difficulty: Intermediate.).

Keywords: LV, left ventricular; RA, right atrial; RV, right ventricular; left ventricular outflow tract obstruction; pericardial effusion; tamponade.
