RVSP Calculator

RVSP Calculator: Estimates Right Ventricular Systolic Pressure from the TR jet velocity and Right Atrial Pressure (RAP). Equivalent to PASP in the absence of pulmonic stenosis.

Peak TR Velocity (m/s)

2.5

Right Atrial Pressure (RAP, mmHg)

Commonly: 3 (IVC < 2.1cm, >50% collapse), 15 (IVC > 2.1cm, <50% collapse), or 5-10 for intermediate cases.

Guidelines & Evidence

Verified

Last Review: 2026-07-17

When to Use

Initial screening and follow-up of suspected Pulmonary Hypertension (PH) during transthoracic echocardiography (TTE).

To assess right ventricular afterload in patients with chronic heart failure or lung disease.

Terminology

In the absence of pulmonary valve or outflow tract stenosis, RVSP (Right Ventricular Systolic Pressure) is physiologically equivalent to PASP (Pulmonary Artery Systolic Pressure).
