ABSTRACT
Objective To evaluate the accuracy and feasibility of estimation of left ventricular dp/dtmax by continuous-wave Doppler mitral regurgitation velocity curve versus cardiac catheterization in patients with mitral incompetence. Methods One hundred and five patients with mitral incompetence were enrolled in this study. The Doppler spectrum of mitral regurgitation velocity was recorded with a speed of 100mm/s. The velocities and time of two points on the ascending slope of the spectrum were calculated directly in order to estimate left ventricular dp/dtmax. In 40 patients, left ventricular pressure and dp/dtmax were measured with cardiac catheterization. Results The correlation coefficient between Doppler dp/dtmax and catheterization dp/dtmax was 0.84 (P
