title: Mitral regurgitation: parameters that affect the correlation between Doppler echocardiography and contrast ventriculography.
abstract: The correlation between Doppler and contrast angiographic estimation of severity of mitral regurgitation was assessed retrospectively in 60 patients with native mitral valve disease. Results showed r = 0.82. Among 15 parameters (demographic, clinical, echocardiographic and hemodynamic) 3 were found to be associated with overestimation of the severity by Doppler: low left ventricular ejection fraction, low cardiac output, and high mean pulmonary artery capillary wedge pressure. On the other hand, a large left atrium was associated with underestimation of mitral regurgitation by Doppler. Based on that data, Doppler results were adjusted in a prospective group of 30 patients with native mitral valve disease. The correlation between contrast ventriculography and uncorrected Doppler results showed r = 0.83, while the corrected Doppler results showed r = 0.91. The study implies that although a good correlation is found between the two modalities for estimation of mitral regurgitation, a better correlation can be achieved by adjusting the Doppler results according to the above-mentioned parameters.
