Doppler Tissue Imaging: A Non-Invasive Technique for Estimation of Left Ventricular End Diastolic Pressure in Severe Mitral Regurgitation

摘要

Background:Conventional Doppler measurements, including mitral inflow and pulmonary venous flow, are used to estimate left ventricular end diastolic pressure (LVEDP). However, these parameters have limitations in predicting LVEDP among patients with mitral regurgitation. This study sought to establish whether the correlation between measurements derived from tissue Doppler echocardiography and LVEDP remains valid in the setting of severe mitral regurgitation.
