One of the most useful applications of intra-operative 2D transesophageal echocardiography (TEE) in noncardiac surgery is qualitative assessment of myocardial function in acutely unstable patients. When hemodynamic instability occurs intraoperatively, TEE can serve as an adjunct to other modalities in diagnosing or ruling out an ischemic event. In fact,

Evaluation of Ventricular Function
1982Modern views of circulatory physiology see the heart and peripheral vasculature as a closely integrated system in which the heart acts as a pump, supplying the energy, with small contributions from peripheral and respiratory musculature, for the circulation of blood (1, 2).

The right ventricle (RV) is highly sensitive to increments of pressure overload. Both acute and chronic excessive pressure overloads lead to right ventricular (RV) maladaptation and subsequent RV failure, which is the main cause of death in patients with pulmonary hypertension (PH).

Echocardiographic measurement of ventricular function
Current Opinion in Critical Care, 2006We review new findings concerning ventricular function in patients in intensive care units with shock or unexplained respiratory distress syndrome analyzed using echocardiography.Bedside echocardiography is not only an imaging technique but should be considered as a hemodynamic method.

We examined 40 patients with ventricular tachycardia (VT) and no evidence of heart disease, and found a 50% prevalence of ventricular late potentials (VLPs) on the signal-averaged electrocardiogram. This finding was associated with a significantly higher content of fibrous tissue on endomyocardial biopsy and a lower right ventricular ejection fraction.

Assessing Ventricular Function
2010In the intact organism the Ventricular Function Curve is usually presented as the relation between Stroke Volume (or Cardiac Output or stroke work)) and ventricular filling. If we make a graph between filling volume and Cardiac Output, we can derive the Ventricular Function Curve from the pressure-volume relation as follows.

Segmental ventricular dysfunction associated with acute myocardial infarction (AMI) is the most common form of acute ventricular failure. Pump failure is the most common cause of death in patients with acute myocardial infarction who do not succumb to fatal arrhythmias.

Global left ventricular (LV) function is an important prognostic parameter and is useful for therapeutic decision-making. Since its introduction, twodimensional (2D) echocardiography has played an important role in the quantitation of LV function. However, the limitations of 2D echocardiography for the accurate determination of cardiac volumes and ...
