The basics of ventricular function
Cardiology in the Young, 1999AbstractThere has been increasing interest in the study of ventricular function in the patient with congenital heart disease. Numerous indexes have been derived for the assessment of ventricular function, suggesting that none is ideal. While the derivation of some measures of ventricular function have relied on advanced mathematical principles, it is ...

This article describes the importance of the right ventricle in both the normal circulation, and in the abnormal milieu of previously palliated or corrected congenital heart disease. The latter group represents natural models of abnormal right ventricular loading that do not exist in any other experimental arena, and their study has provided insights ...

BACKGROUND We conducted a multicenter, placebo-controlled trial designed to establish the efficacy and safety of carvedilol, a "third-generation" beta -blocking agent with vasodilator properties, in chronic heart failure.

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.

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).

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,

The right ventricle (RV) has historically been given less importance than the left. There are important anatomical differences, including several intracardiac structures that may complicate echocardiographic assessments. The right heart is sensitive to changes in pressure and its function is affected by common interventions in critical care such as ...

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.

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).
