Figure 2 Systolic frame, apical four-chamber views in another patient with dyspnea: (A) hand-carried echocardiography (with color power Doppler) (arrow points to tricuspid regurgitation); (B) standard echocardiography (with color Doppler). Note that severe tricuspid regurgitation was seen easily in the right atrium by standard echocardiography (B) and not by hand-carried echocardiography (A). In addition, this patient has severe pulmonary hypertension (note continuous-wave Doppler with a 4-m/s velocity of tricuspid regurgitation [arrow] on standard echocardiography (C); this indicates a pulmonary artery systolic pressure of approximately 75 mm Hg). This critical information could not be obtained with hand-carried echocardiography, which lacks spectral Doppler. LA = left atrium; LV = left ventricle; RA = right atrium; RV = right ventricle.
