Evaluation of left ventricular functions by speckle‐tracking echocardiography in coarctation patients

Abstract

Coarctation of the aorta (CoA) is a relatively common defect that occurs in the general population at a rate of 0.06%-0.08%, constituting 6%-8% of congenital heart disease. 1,2 CoA can be clinically asymptomatic, or it may present with a shock in infancy and may present with systemic hypertension, intracranial bleeding, and heart failure in adults. 3 Even if CoA is successfully treated, systemic hypertension can lead to the development of late complications such as left ventricular (LV) hypertrophy, heart failure, coronary artery disease, stroke, or sudden cardiac death. 4,5 Left ventricular ejection fraction (EF) is known not to be a sensitive marker for the detection of subclinical LV systolic dysfunction, and tissue Doppler imaging has its own limitations, including angle dependency. 6,7 Two-dimensional speckle-tracking echocardiography (2D-STE) is a novel used method in terms of showing regional subclinical myocardial functions. 8 The early detection of subclinical myocardial dysfunction in patients with CoA is essential for planning

Association between epicardial adipose tissue and myocardial work by non-invasive left ventricular pressure-strain loop in people with suspected metabolic syndrome

“…Moreover, several inflammatory substances released from adipocytes, such as resistin have been suggested to contribute toward the adverse effects of obesity on the heart by promoting myocardial hypertrophy and dysfunction 21 . Extensive research has reported that the myocardial strain obtained by two-dimensional speckle tracking imaging can make left ventricular quantization beyond LVEF a better prognostic marker of cardiac events 22 – 24 . In this study, no significant difference in AAO, LAD, LVEDd, LVEF, A and E/e′ was reported between the thin and thick EAT groups.…”
