A: Muscle biopsy with hematoxylin and eosin staining (× 100) showed inflammatory cell infiltration; B: Electrocardiography indicated a normal sinus rhythm; C: A four-chamber view showed an enlarged right atrium, right ventricle, and left atrium; D: A long axis view of the pulmonary artery indicated widening of that artery; E: Doppler echocardiography showed that the peak tricuspid regurgitation velocity was 3.4 m/s, and the tricuspid regurgitation pressure gradient was 46 mmHg; F: Bicuspid valve doppler indicated reduced diastolic function. RV: Right ventricular; LV: Left ventricle; RA: Right atrium; LA: Left atrium; PA: Pulmonary artery.
