Afterload is the peripheral or systemic vascular resistance to which the left ventricle is confronted by the expelling blood into the arterial system. Haemodynamic performance in terms of energy expenditure.

Afterload mismatch is a scenario in which the ventricular performance is not well coupled to the afterload it encounters, which increases myocardial oxygen consumption and decreases cardiac energy ef fi …

Also known as systemic vascular resistance (SVR), afterload reflects changes in the radius of the arterioles. The arterioles are resistant vessels because they constrict or relax.

In this report we aim to demonstrate the value of the afterload to build a surgical indication in valvular surgery. Ventricular function is usually assumed to be reflected only by ejection fraction (EF), and …

Glossary: Afterload The mechanical "load" on the ventricle during ejection. Under normal physiological conditions, this is determined by the arterial system. Indices of afterload include, aortic pressure, …

LLC 2010 Abstract A clinical comparison, of two methods of afterload assessment, has been made. The first method, systemic vascular resistance index (SVRi), is based upon the traditional formula for …

This vignette highlights the hemodynamic conse-quences of flow-flatlining, profound in some cases, and the contributory effect of afterload-reducing vasoactive medications.
