Relation between pressure difference across the aortic valve and left ventricular outflow.
Abstract
Equations are presented to relate left ventricular-aortic pressure difference and flow. The relative importance of fluid inertia and friction are evaluated and the errors introduced by the neglect of compliance are estimated. The equations are used to calculate pressure differences for both normal conditions and simulated aortic stenosis and to explain the timing of the reversal of the pressure difference.
