Background. To minimize decreases in left ventricular (LV) compliance immediately after rat heart transplantation, we tested several different methods of myocardial protection. Materials and methods. Five groups of ACI rat hearts (n = 6 each) were ar

Objective.We have found diastolic properties of the rat heart extremely sensitive to the method used to induce arrest. Accordingly, we sought to develop a reliable solution for measuring the LV pressure–volume relationship (LVPVR) in the rat. Mater

Two-dimensional echocardiography has been useful for measuring changes in left ventricular mass (LVM) at constant left ventricular end-diastolic volume (LVEDV). Two-dimensional echocardiographic measurement of LVM changes during variations in LVEDV r

Background Perfusion-induced edema reduces diastolic compliance in isolated hearts, but this effect and the time for edema to resolve after blood reperfusion have not been defined in large animals. Methods Edema was induced by coronary perfusion with

Conductance (COND) measurements of left ventricular volume, satisfactory under steady state conditions, may be altered by extraneous factors during complex experiments or cardiac surgery. A reference technique is needed to detect changes in the COND-

Decreased systolic ventricular function and compliance and increased left ventricular edema and mass have been demonstrated in cardiac allograft rejection. Whether decreased left ventricular compliance in rejection is caused by myocardial edema has n

Ventricular fibrillation (VF) is induced during implantable cardioverter defibrillator insertion and can result in cardiovascular collapse. The relation between repeated VF trials of varying duration and systolic blood pressure (SBP) recovery rate wa

Background. The purpose of this study was to examine regional variation in myocardial water content (%MWC) throughout the iatrogenically edematous pig heart. Methods. Edema was induced by hemodilution in domestic swine (n = 26). Hearts were arrested

Background We tested the hypothesis that pretreatment with the antioxidant probucol attenuates reperfusion-induced diastolic abnormalities in the heterotopic rat cardiac isograft. Methods American Cancer Institute rats ( n = 48) were divided into 6 g

Recent studies found that edema, histology, and left ventricular diastolic compliance exhibit quantitative relationships in rats. Edema due to low osmolarity coronary perfusates increases myocardial water content and histologic edema score and decrea
