Adult Congenital Heart Disease
Congenital heart disease (CHD) is common, occurring—if bicuspid aortic valve (AV) is excluded—in approximately 1% of all live births. The most common defects and the incidence of each are outlined…

In the ICU, transthoracic imaging is usually the first echocardiographic imaging modality performed and may yield sufficient clinical information without the need to proceed to TEE. TTE and TEE both…
Ultrasound waves are unable to penetrate aerated lung tissue. Historically, this has limited lung ultrasound almost exclusively to the evaluation of pleural effusions. More recently, the recognition that analysis of…
In the practice guidelines published in 1996 by the American Stroke Association and (SCA), the assessment of valve replacement surgery is a category II indication for transesophageal echocardiography (TEE) (TEE…
The mitral valve (MV) is ideally suited to examination with transesophageal echocardiography (TEE) because it lies close to the esophagus and is separated from the transducer by the blood-filled left…
The importance of the right ventricle as a cause of perioperative morbidity is being increasingly recognized. Right ventricular (RV) failure is responsible for approximately one fifth of cases of circulatory…
Hemodynamic instability encompasses hypotension, low or (pathologically) high cardiac output, and abnormal filling pressures. Assessing hemodynamic instability is one of the most important indications for echocardiography in the operating room…
The examination of the thoracic aorta is an essential component of both routine and emergent echocardiographic examinations. The aorta and its major branches can be visualized with echocardiography using a…
The aortic valve (AV), left ventricular outflow tract (LVOT), and aortic root are positioned in the center of the heart close to the midesophagus and are separated from it by…
The aim in this chapter is to explain the theory underlying some quantitative and semiquantitative methods used in perioperative TEE to estimate cardiac output, to evaluate the orifice size in…
