Left ventricular systolic function

2018

Abstract Chapter 6 is subdivided into three sections: global LV systolic function, regional LV systolic function, and cardiomyopathies. In Section 1, commonly used indices of global systolic function, such as fractional area change and ejection fraction, are reviewed, along with their limitations related to oesophageal imaging. The relationship between stroke volume and ejection fraction is explored. Newer techniques such as quantitative 3D imaging and strain-rate imaging are described. In Section 2, the causes of regional systolic dysfunction are reviewed, along with the different aetiologies of real and apparent segmental wall motion abnormalities. Complications of myocardial infarction such as mitral regurgitation, true and false LV aneurysms, and ventricular septal rupture are also dealt with in this section. Section 3 provides an overview of the echocardiographic findings associated with various cardiomyopathies: dilated, hypertrophic, restrictive, acute myocarditis, LV non-compaction, and Takotsubo.

Left ventricular diastolic function

Brian D. Hoit · Critical Care Medicine · 2007

Cardiovascular morbidity and mortality resulting from congestive heart failure are major concerns for the critical care physician. Although heart failure is commonly associated with impaired systolic function, in up to one half of cases, heart failure occurs exclusively on the basis of an impairment of diastolic function. Diastole is the summation of processes by which the heart loses its ability to generate force and shorten and returns to its precontractile state. The two principal processes responsible for diastole are relaxation and passive pressure-volume properties of the ventricle. Echocardiography provides a comprehensive, noninvasive evaluation of diastolic filling of the ventricle, myocardial relaxation, and ventricular stiffness; the information obtained by echocardiography has prognostic value and is a guide to proper therapy. This article reviews the physiology of diastole, the pathogenesis of diastolic heart failure, and the diagnosis of diastolic dysfunction, with a focus on the diagnostic utility of echocardiography and an emphasis on those areas of greatest interest to the critical care physician.

Left ventricular systolic function

2025

Abstract The evaluation of systolic left ventricular (LV) function is an important component of every transoesophageal echocardiographic examination. Prior to surgery, it helps to identify high-risk patients. In patients with haemodynamic instability, assessment of LV function guides fluid and inotropic therapy. This chapter is subdivided into three sections: (1) global left ventricular (LV) systolic function; (2) regional LV systolic function; and (3) cardiomyopathies. In the first section, commonly used indices of global systolic function are reviewed, along with their limitations related to oesophageal imaging. In the second section, the causes of regional systolic dysfunction are reviewed, along with the different aetiologies of segmental wall motion abnormalities and resultant complications. The third section provides an overview of the echocardiographic findings associated with various cardiomyopathies.

Left Ventricular Diastolic Function

Richard Taylor · Journal of diagnostic medical sonography · 1993

Two-dimensional echocafdiography has gained widespread acceptance I as the procedure of choice to evaluate left ventricular function. In the last decade, the importance of diastolic function in the overall performance of the left ventricle has received much attention. Recent evidence suggests that diastolic dysfunction may contribute to symptoms of left heart failure in many patients, including those with normal sys tolic function. Alterations in transmitral Dop pler flow velocity patterns have been used to assess changes in left ventricular diastolic func tion. This article reviews the concept and clin ical signincance of diastolic function and the assessment of diastolic function by Doppler echocardiography.

Left Ventricular Aneurysmectomy in Patients with Poor Left Ventricular Function

S. Oxelbark, Finn Mannting, M. G. Morgan et al. · Scandinavian Journal of Thoracic and Cardiovascular Surgery · 1992

Physical performance and left ventricular (LV) function in the resting state were assessed in 22 patients with postinfarction anterior-apical left ventricular aneurysm (LVA) and global ejection fraction less than or equal to 20% who subsequently underwent radical LVA resection. The basic findings in the 20 survivors of surgery were significant improvement of global systolic LV function and more or less complete recovery of regional ejection fraction in the predominantly viable low and high lateral LV wall. This improvement was evident in patients with concomitant bypass grafting as well as in those with isolated and ungraftable lesions of the left anterior descending (LAD) coronary artery. We conclude that postinfarction anterior-apical LVA in a poorly functioning LV is suitable for surgical treatment, which can be accomplished with acceptable risk. All graftable stenotic major coronary arteries should be bypassed, in addition to the LVA resection, but a minority of patients with isolated, ungraftable LAD disease are likely to benefit from aneurysmectomy alone.
