Post systolic shortening
Web19 Oct 2024 · The PSI is associated with most validated echocardiographic and invasive measures of cardiac systolic and diastolic function and was associated with invasively measured LV pressure decline in early diastole and dP/dt min. Post-systolic shortening (PSS) does not contribute to the ejection of blood and may inhibit diastolic filling. We … WebBackground: Speckle-tracking echocardiography (STE) has gained increasing value in the evaluation of congenital heart diseases (CHD); however, its use in pediatric cardiac surgery is limited. Aim: To evaluate left ventricular (LV) systolic impairment after biventricular pediatric cardiac surgery by STE strain (ε) analysis. Methods: We prospectively enrolled …

WebPost-systolic shortening and thickening, defined as the magnitude of segment shortening or wall thickening that occurred after end systole, was measured in peripheral and central … WebConclusion: Patients in this family with LQTS type 3 showed post-systolic shortening, as well as both left and right ventricular diastolic dysfunction. The underlying mechanism remains to be elucidated but the persistent sodium inward current leading to calcium overload might play a role, in particular regarding diastolic dysfunction.
Web25 Aug 2024 · Post-systolic shortening index (PSI) is a phenomenon of regional contraction occurring after end-systole, and is most commonly detected by speckle tracking … Web6 Nov 2024 · The postsystolic shortening represented 9.7 ± 1.7% ( P < 0.01) and 14.2 ± 2.4% ( P < 0.01) of end-diastolic segment length by SDE and sonomicrometry, respectively. Consistent with the velocity changes, we found reversal of the early diastolic pressure gradient from the LV apex to outflow tract.
