Continuous-Wave doppler echocardiography was used to estimate the Pressure gradient in 55
children with congenital heart disease.
To test whether the Doppler method would be useful for evaluation and management of pediatric
patients with ventricular septal defect (VSD)), pulmonic stenosis (PS), tricuspid regurgitation (TR),
we recorded the maximal velocity (Vmax) of transseptal, pulmonary and regurgitant tricuspid jet
flows and calculated the pressure gradients used by... |
