Visualizes heart in real time with ultrasound; Doppler recordings noninvasively assess hemodynamics and abnormal flow patterns (Table 114-1 and Fig. 114-1). Imaging may be compromised in pts with chronic obstructive lung disease, thick chest wall, or narrow intercostal spaces. Transesophageal echocardiography (TEE) is performed when higher resolution images of cardiac structures is required.
Cardiac chambers: size, hypertrophy, wall motion abnormalities
Valves: morphology and motion
Pericardium: effusion, tamponade
Aorta: aneurysm, dissection
Assess intracardiac masses
Valvular stenosis and regurgitation
Approximate intracardiac pressures
Superior to 2-D echo to identify:
Cardiac source of embolism
Prosthetic valve dysfunction
Assess myocardial ischemia and viability
