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'...
متن کاملEnd-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...

BASIC RESEARCH on the ventricular pressure-volume loop diagram has been revived.' Several investigators2-8 proposed that the relationship of end-systolic pressure (or wall stress) to end-systolic volume (or some dimension) may be useful in evaluating the contractile state of the heart. Grossman et al. published an important clinical study" in 1977; many others followed. At the 1980 annual meeti...
متن کاملVentriculo-arterial coupling and the areas under the end-systolic pressure-volume relation.
Ventriculo-arterial coupling is expressed as the ratio Emax/eam (maximum ventricular elastance/arterial elastance). Different areas under the end-systolic pressure-volume relation (ESPVR) are expressed in terms of Emax/eam. The explicit inclusion of the active force of the myocardium in the mathematical formalism describing the pressure-volume relation (PVR) leads to new insight into the mechan...
