Redfield, MD, Rochesteg Minnesota Pulmonary venous (PV) vdodties obtained by transthoracic echocardiography are used to assess diastolic function. The systolic/diastolic (S/D) PV velocity ratio is increased with impaired early diastolic filling and decreased with elevated mean left atrial pressure (LAP). Mitral stenosis (MS) is characterized by impaired filling and elevated LAP. We hypothesized that the S/D ratio would be increased in MS except in severe MS with high LAP, in which the S/D ratio would be decreased. Patients with isolated MS who underwent transthoracic echocardiography were stud- Interrogation of the pulmonary venous velocity patterns is increasingly used to assess diastolic function and mitral regurgitation? '2 Elegant studies with hemodynamic correlation have demonstrated that reduction in the ratio of puhnonary venous systolic velocity/diastolic velocity (S/D) or the ratio of the time-velocity integral of the systolic velocity curve to that of the total pulmonary venous velocity curves is indicative of elevated left atrial pressures in patients with sinus rhythm. Patients who have delayed left ventricular relaxation have decreased diastolic velocity, reflecting the impairment to early left ventricular filling with a pattern of increased S/D ratios, a,4 Mitral stenosis is a disorder characterized by both impaired ventricular filling caused by the stenotic valve and elevation of left atrial pressure. The characteristic pulmonary venous velocity curves in patients with mitral stenosis have not been clearly elucidated. The impairment in left ventricular filling should result in an increased S/D ratio.
