AB  - OBJECTIVE: Few reports have been published on the Doppler-derived 
      echocardiographic data for pulmonary valve prostheses (PVPs). The aim of this 
      study was to provide a comprehensive Doppler echocardiographic assessment of 
      PVPs. METHODS: We studied 40 patients (mean age 24.2) with PVPs: 13 (32.5%) 
      mechanical and 27 (67.5%) bioprosthetic valves. After clinical evaluation, all 
      patients underwent complete, two-dimensional and Doppler studies. RESULTS: In 30 
      patients with normally functioning PVPs, the mean (SD) peak velocity was 2.33 
      (0.36) m/s with an average peak pressure gradient of 22.69 (6.7) mm Hg and an 
      average mean pressure gradient of 12.5 (4.1) mm Hg. The mean PVPs velocity time 
      integral (VTI) was 47.49 (12.78) cm with mean right ventricle outflow tract/peak 
      velocity (PV) VTI ratio 0.43 (0.14), mean PVPs effective orifice area was 1.63 
      (0.36) cm(2). Metallic PVPs had significantly better hemodynamic Doppler study 
      compared with biologic PVPs. In 9 patients with PVP malfunction, average peak 
      PVPs velocity, average peak pressure gradient, mean pressure gradient, PV VTI, 
      PV/left ventricle outflow tract VTI ratio was significantly increased (P < 0.05). 
      CONCLUSION: This study contributes to establishing the normal range for Doppler 
      hemodynamics in various PVPs.
