Examples of color Doppler mapping still frames obtained from hand-held echocardiographic examinations of four distinct patients. (A) Parasternal long axis view obtained from the same patient as in Fig. 2A. A large regurgitant jet was consistent with massive aortic insufficiency. (B) Apical four-chamber view obtained from a patient ventilated for an acute pulmonary edema and associated systolic murmur. Color Doppler mapping disclosed a severe mitral regurgitation associated with extended regional wall motion abnormality consistent with an ischemic cardiopathy. (C) Apical four-chamber view obtained from a ventilated patient with shock. Hand-held echocardiography revealed a severe left ventricular systolic dysfunction. Color Doppler mapping depicted a massive tricuspid regurgitation reflecting a severe pulmonary hypertension (arrow indicates mitral valve prosthesis). (D) Parasternal long axis view obtained from a patient presenting with septic shock and new onset systolic murmur. Color Doppler identified an aorto-right ventricular fistula (arrow) associated with aortic regurgitation. Two-dimensional examination showed large aortic vegetations and blood cultures yielded Streptococcus bovis. LV, left ventricle; RV, right ventricle; LA, left atrium; RA, right atrium; Ao, ascending aorta.
