case_images: Chest x-ray showed areas of consolidation on both sides of the lungs and increased cardiothoracic ratio (Figure 1). Right ventricular inflow view in systole showing thickened, immobile leaflets of tricuspid valve in a fixed open position, causing mal-coaptation and severe regurgitation without stenosis (see Figure 3 and Video 1).
case_images: Electrocardiography of the patient. (A). Sinus rhythm with QTc
  prolongation (B). Atrial flutter (C). Atrioventricular dissociation
  and ventricular extra-systole (D). Holter monitorization revealed
  non-sustained ventricular tachycardia.

case_images: The electrocardiogram showed sinus rhythm with 70/min heart rate and prolongation of QTc value with 0.46 seconds (Figure 2-A). On the seventh day of hospitalization, the electrocardiogram showed atrial flutter (Figure 2-B). In the second week, the patient developed acute renal insufficiency and the electrocardiogram showed atrioventricular dissociation and ventricular extra-systole (Figure 2-C). Holter monitorization revealed atrioventricular dissociation and non-sustained ventricular tachycardia (Figure 2-D).
case_images: Transthoracic echocardiography from the parasternal view by tilting
  transducer inferomedially exploring the right atrium (RA) and right
  ventricle (RV) inflow tract; immobile leaflets of the tricuspid
  valve (TV) leading to severe insufficiency.
