A comparison of pulmonary valve gradient measurement by doppler and catheterization

In this study, trans-pulmonic valvular gradient of 51 patients with congenital pulmonary stenosis measured by CW-Doppler and cardiac catheterization were compared to find whether they are comparable and if Doppler method is accurate enough for interventional decision-making. Results showed that findings in both methods were comparable and Doppler method is accurate and enough for clinical decision.
