135 CORRELATION OF PEAK SYSTOLIC PRESSURE/END SYSTOLIC VOLUME(PSP/ESV) AND END SYSTOUC PRESSURE/END SYSTOLIC VOLUME (ESP/ESV) RATIOS

Peak Systolic Velocity / End Diastolic Velocity PI = ( Peak Systolic Velocity – End

End-systolic pressure-volume relations.

tive prosthetic orifice size may have to be performed at least a few weeks after valve insertion. Second, in some patients, the problem is compounded by the small size of the annulus compared with the size of the patient. My article was not written just to highlight the difficulties of a small aortic annulus. Dr. Kinsley's ability to insert a prosthetic valve size commensurate with the patient'...

Correlation of Mitral Annular Plane Systolic Excursion (MAPSE) and Tissue Doppler peak Systolic Velocity with Left Ventricular Systolic Function

The assessment of left ventricular systolic function is the most common indication for performing an echocardiogram, however, no perfect measure of systolic function exists and there are limitations to currently available methods [1]. The most widely used measurement of left ventricular systolic function is the ejection fraction, which also provides important prognostic information [2]. However...

Effects of stroke volume and velocity of ejection on end-systolic pressure of canine left ventricle. End-systolic volume clamping.

To study the effects of contraction mode on ventricular end-systolic pressure-volume relationship, we compared the end-systolic pressure of isovolumic contraction with that of ejecting contraction at an identical end-systolic volume. The left ventricle of excised cross-circulated canine hearts was fitted with a water-filled balloon. The balloon was connected to a hydraulic pump that allowed the...

End-Systolic and End-Diastolic Pressure-Volume Relations in Humans

The influence of acute coronary occlusion on systolic and diastolic left ventricular pressurevolume relations was studied in 10 patients undergoing percutaneous transluminal coronary angioplasty (PTCA). Pressure-volume relations were obtained by conductance catheter and micromanometer techniques and with volume load altered by transient inferior vena caval occlusion. End-systolic and end-diasto...
