This pathologic mode describes mitral locking insufficiency leading to blood regurgitation from the right ventricle to the venae cavae in diastolic phase.

Tricupsid valve failure

Turbulent regurgitation in diastolic phase

The mathematical description of this pathology is determined by the equation describing blood flow through tricupsid valve:

(36)

The second part of the formula (36) describes the process of blood regurgitation through tricupsid valve in diastolic phase in case of valvular locking defect (0 < r_VLHR< 1). In its normal state r_VLHR takes on the value 0.

The modelling is realized by putting a scroller "Degree of pathogenicity" on the values from 0 (pathology absence) to 100 (the highest severity level). For the highest severity level there is a value of r_VLHR= 0.3 (the level of blood regurgitation through pulmonary valve amounts to 50% from left ventricular stroke volume).
