[Contractility and left ventricular filling in heart failure: an echocardiographic evaluation].
In this paper we analyze the possibility of investigating the various modalities of pump function alteration by the echocardiographic technique through examination of the different parts of the cardiac cycle. While M-Mode and 2D echocardiography make a precise assessment of the systolic function parameters possible, with the Echo-Doppler technique we can study diastolic function and obtain information about many hemodynamic parameters. "Strain dependent" and "strain independent" diastolic function are studied almost exclusively with the Echo-Doppler technique: the diagnosis of restrictive cardiomyopathy can be established without invasive procedures such as cardiac catheterization. We suggest that, in most heart diseases with cardiac failure, diastolic and systolic dysfunction coexist: in mitral and aortic regurgitation, echocardiography can give precise information on the presence of ventricular dysfunction, even in the presence of very few or no symptoms, which helps the cardiologist make an early surgical or non surgical decision when dealing with such valve pathologies.
