Fig. 1.
Transthoracic echocardiographic images before use of carfilzomib. Parasternal long-axis view at end diastole and end-systole (A), apical four-chamber view at end-diastole (B), and continuous Doppler waveforms of tricuspid velocity (C) are presented. The findings denied any geometric and functional abnormalities in left ventricle and right ventricle (A, B). Peak tricuspid regurgitation pressure gradient was 23 mmHg (C).
LV, left ventricle; RV, right ventricle.
