Nonobstructive left ventricular ejection pressure gradients in man.
Simultaneous intraventricular pressure gradients and ejection flow patterns were measured by a multisensor catheter in 6 patients with normal left ventricular function and no valve abnormalities, at rest and in exercise. Peak measured intraventricular pressure gradients were attained very early in ejection, amounted to 6.7 +/- 1.9 (SD) mm Hg at rest, and were intensified to 13.0 +/- 2.3 mm Hg d...
متن کاملDoppler-derived ejection intraventricular pressure gradients provide a reliable assessment of left ventricular systolic chamber function.
BACKGROUND Ejection intraventricular pressure gradients are caused by the systolic force developed by the left ventricle (LV). By postprocessing color Doppler M-mode (CDMM) images, we can measure noninvasively the ejection intraventricular pressure difference (EIVPD) between the LV apex and the outflow tract. This study was designed to assess the value of Doppler-derived EIVPDs as noninvasive i...
متن کاملPredictors of increased left ventricular filling pressure in dialysis patients with preserved left ventricular ejection fraction.
AIM To study the left and right ventricular function and to assess the predictors of increased left ventricular (LV) filling pressure in dialysis patients with preserved LV ejection fraction. METHODS This study included 63 consecutive patients (age 57+/-14 years, 57% women) with end-stage renal failure. Echocardiography, including tissue Doppler measurements, was performed in all patients. Ba...
متن کاملThe Study of Left Ventricular Function in Man by Increasing Resistance to Ventricular Ejection with Angiotensin.
IN spite of the development of refined hemodynamic and angiographic technics for evaluation of the mechanical function of the heart valvJes, the assessment of the function of the myocardium remains a difficult problem in man. Although the ventricular end-diastolic pressure has been employed frequently for determining the presence or absence of heart failure, a number of factors other than myoca...
متن کاملLeft ventricular diastolic pressure-volume relations in man.
Diastolic function of the left ventricle was analysed in patients with different cardiac diseases: acute and chronic volume overload (in aortic and mitral incompetence), pressure overload and inappropriate ventricular hypertrophy (aortic stenosis and hypertrophic cardiomyopathy), congestive cardiomyopathy, and constrictive pericarditis. Most patients were receiving digitalis therapy at the time...
