Sentence examples for left ventricular preload from inspiring English sources

Decreased compliance of the aorta increases systolic pressure and left ventricular preload, resulting in elevated stress on the left ventricular myocardium during the systolic phase.

VA-ECMO decreases left ventricular preload and increases afterload, leading to blood stasis in the left heart, and it can put the patient at potential risk for bioprosthetic valve thrombosis [2, 5].

Objectives: The aim of this study was to compare the following approaches to assess left ventricular preload by transesophageal echocardiography (TEE): left ventricular end-diastolic volume index (LVEDVI) determined by using the method of disc summation (LVEDVIMd) and left ventricular end-diastolic area index (LVEDAI) were compared with LVEDVI assessed by the modified Simpson formula (LVEDVISi).

Fig. 2 Left ventricular preload.

PLE significantly reduced left ventricular preload.

Main outcome was left ventricular preload measured as left ventricular end-diastolic area.

Before esophagectomy, her respiratory function was normal and her echocardiography indicated disappearance of secondary pulmonary hypertension and subsequent increased left ventricular preload (Table 1).

These data indicate that, while transient pulmonary arterial occlusion reduces left ventricular preload, the concomitant increase in right ventricular systolic pressure, which is the pressure external to the interventricular septal segment of the left ventricle, augments septal shortening and assists left ventricular pump function at a given preload through direct systolic ventricular interaction.

This study investigated whether the combination of central venous pressure (CVP) and left ventricular functional preload parameters, such as stroke volume variation (SVV) and pulse pressure variation (PPV), can be used for the detection of acute RVF and for guidance of volume therapy.

For instance, iNO has been shown to improve cardiac function not only through unloading the right ventricle (RV) and thus improving left ventricular (LV) preload, but also through direct effects on contractility [ 45].

Studies have shown that pediatric emergency medicine physicians with POCUS training are both reliable and accurate in assessing left ventricular function and preload by estimating IVC collapsibility when compared to cardiologists/echocardiographers [144, 145].
