          For evaluation of pulmonary venous flow (PVF) in mitral stenosis, transthoracic and transesophageal echocardiography were performed in 33 patients with mitral stenosis and 20 normal controls. The peak systolic flow velocity of the PVF was significantly lower in patients with mitral stenosis and atrial fibrillation. The peak diastolic flow velocity of the PVF was significantly lower in the patients with mitral stenosis than in normal controls. The diastolic wave recorded as laminar flow in the mitral stenosis group showed a peak in the rapid filling phase with a gradually descending slope of velocity during mid to late diastole. There was a significant negative correlation between the peak diastolic flow velocity of the PVF and the pressure half time from transmitral flow obtained by continuous wave Doppler in the mitral stenosis group. These results demonstrate that evaluation of the PVF is helpful in understanding hemodynamic events between the left atrium and left ventricle in patients with mitral stenosis.
