validity of pulse wave tissue doppler imaging in predicting elevated left ventricular end diastolic pressure in patients with coronary artery disease

ABSTRACT

Background: Elevated left ventricular filling pressures are the main physiological consequence of diastolic dysfunction and carry a prognostic significance in different cardiovascular diseases including coronary artery diseases, and cardiomyopathies. Filling pressures are considered elevated when the mean pulmonary capillary wedge pressure is >12mmHg or when the left ventricular end diastolic pressure is >/= 16 mm Hg. a reliable noninvasive method for the estimation of LVEDP is needed
