Clinical Uses of Echocardiography

2-D EchoTransesophageal Echocardiography
Cardiac chambers: size, hypertrophy, wall motion abnormalities Superior to 2-D echo to identify: Infective endocarditis
Valves: morphology and motion Cardiac source of embolism
Pericardium: effusion, tamponade Prosthetic valve dysfunction
Aorta: aneurysm, dissection Aortic dissection
Assess intracardiac masses
Doppler EchocardiographyStress Echocardiography
Valvular stenosis and regurgitationAssess myocardial ischemia and viability
Intracardiac shunts
Diastolic filling/dysfunction
Approximate intracardiac pressures
