Tricuspid stenosis hemodynamic evaluation is done in which phase of the cardiac cycle?

Tricuspid stenosis primarily affects the flow of blood through the tricuspid valve during the diastolic phase of the cardiac cycle. This is the period when the heart relaxes and the ventricles fill with blood. In the case of tricuspid stenosis, the narrowed valve impedes normal blood flow from the right atrium to the right ventricle, resulting in increased pressures in the right atrium and decreased filling of the right ventricle.

Hemodynamic evaluation during diastole allows clinicians to assess the severity of the stenosis by evaluating pressure gradients across the tricuspid valve. This involves measuring the pressures in the right atrium and right ventricle, which helps in determining the impact of the stenosis on right heart dynamics. Understanding how the heart functions during this phase is crucial for diagnosing and managing conditions related to tricuspid stenosis effectively.
