ventricular interdependence
The mechanical and hemodynamic interaction between the right and left ventricles through the shared interventricular septum and pericardium.
Full Definition
Ventricular interdependence describes how the function of one ventricle directly influences the other through shared anatomical structures, particularly the interventricular septum and pericardial constraint. This phenomenon becomes clinically significant in conditions causing acute ventricular dilation, where increased pressure in one ventricle shifts the septum and impairs filling of the contralateral ventricle. In cardiovascular anesthesiology, understanding ventricular interdependence is crucial for managing patients with right heart failure, pulmonary embolism, or during procedures affecting ventricular loading conditions.
Usage
Usage note: Hyphenate when used as a compound modifier before a noun.
