Abstract

Previous studies relating Doppler parameters and pulmonary capillary wedgepressures (PCWP) typically exclude patients with severe mitral regurgitation (MR). We evaluated the effects of varying degrees of chronic MR on the Doppler estimation of PCWP. PCWP and mitral Doppler profiles were obtained in 88 patients (mean age 55 +/- 8 years) with severe left ventricular (IV) dysfunction (mean ejection fraction 23% +/- 5%). Patients were classified byseverity of MR. Patients with severe MR had greater left atrial areas, IV end-diastolic volumes, and mean PCWPs and lower ejection fractions (each P < .01). In patients with mild MR, multiple echocardiographic parameters correlated with PCWP; however, with worsening MR, only deceleration time strongly related to PCWP. From stepwise multivariate analysis, deceleration timewas the best independent predictor of PCWP overall, and it was the only predictor in patients with moderate or severe MR. Doppler-derived early mitral deceleration time reliably predicts PCWP in patients with severe IV dysfunction irrespective of degree of MR.
