“…While we did not find an association between global LVLS and mortality, reduction of the basal anterior segmental strain was associated with increased mortality. The present finding is of interest as the LV base is the site of the higher peak systolic radial velocities of the anterior and inferior segments 25 , suggesting the relatively higher dynamics of anteroposterior versus lateral ventricular wall motion in systole 25 . Likewise, there was a suggestion of an increase in mortality in patients with abnormal TMAD.…”

Summary Septic cardiomyopathy is commonly encountered in patients with severe sepsis and septic shock. This study explores whether novel global and segmental echocardiographic markers of myocardial deformation, using two-dimensional speckle tracking, are associated with adverse sepsis outcomes. We conducted a retrospective observational feasibility study, at a tertiary care centre, of patients admitted to the ICU with a diagnosis of sepsis who underwent an echocardiogram within the first week of sepsis diagnosis. Data were collected on chamber dimensions, systolic and diastolic function, demographics, haemodynamics, and laboratory parameters. Global and segmental left ventricular longitudinal strain (LVLS) and tissue mitral annular displacement (TMAD) were assessed on 12 left ventricular segments and six mitral annulus segments in apical views, respectively. We explored associations of abnormal LVLS and TMAD with duration of mechanical ventilation, hospital length of stay, and mortality. Fifty-four patients were included. Global LVLS was not associated with any of the primary study endpoints. However, reduced systolic LVLS of the basal anterior segment was associated with in-hospital mortality. There was a suggestion that patients with a reduced global TMAD were associated with an increased risk of mortality and a short length of hospital stay but these associations were not statistically significant. Reduced global LVLS was associated with lower ejection fraction. Reduced global TMAD was associated with reduced global and segmental LVLS, reduced left ventricular ejection fraction, and increased left ventricular end-systolic and end-diastolic volumes. Speckle-tracking echocardiography can be performed feasibly in patients in sepsis. Global and segmental left ventricular deformation indices are associated with ejection fraction. Further studies need to evaluate the ability of these new indices to predict sepsis outcomes.

“…However, a stunning localized effect with minimal release of myocardial enzymes, such as in Takotsubo syndrome, should be considered [51]. Anyway, no differences in ventricular deformation pattern, perfusion, and late gadolinium enhancement (LGE) in the POPS group were reported [24,26,45,46].…”

The interventricular septum (IVS) is a core myocardial structure involved in biventricular coupling and performance. Physiologically, during systole, it moves symmetrically toward the center of the left ventricle (LV) and opposite during diastole. Several pathological conditions produce a reversal or paradoxical septal motion, such as after uncomplicated cardiac surgery (CS). The postoperative paradoxical septum (POPS) was observed in a high rate of cases, representing a unicum in the panorama of paradoxical septa as it does not induce significant ventricular morpho-functional alterations nor negative clinical impact. Although it was previously considered a postoperative event, evidence suggests that it might also appear during surgery and gradually resolve over time. The mechanism behind this phenomenon is still debated. In this article, we will provide a comprehensive review of the various theories generated over the past fifty years to explain its pathological basis. Finally, we will attempt to give a heuristic interpretation of the biventricular postoperative motion pattern based on the switch of the ventricular anchor points.

“…Pilot images, followed by horizontal and vertical long axis cine images, were acquired using a steady-state Free Precession (TrueFISP) pulse sequence. Cine images for navigator-gated high temporal resolution phase contrast velocity mapping were acquired using a black blood segmented k-space spoiled gradient echo sequence [18,19] with a temporal resolution of 13.8 ms, with prospective ECG-gating and advanced respiratory navigator gating (TR=13.8 ms, flip angle=15º, bandwidth=650 Hz/pixel, FOV=400 x 300 mm, matrix=256 x 96), as previously described [16,[20][21][22][23]. Three equidistant short axis images were acquired for the LV base, mid-ventricle and apex.…”

“…The duration of the cardiac cycle was determined by the R-R interval on the electrocardiogram, with end systole defined as the smallest LV cavity. The cardiac phases were subsequently calculated and normalized for the entire group based on their average duration during a cardiac cycle [16,20,23].…”

Objective: To obtain new details of three-dimensional Left Ventricular (LV) wall motion in patients with Coronary Artery Disease (CAD) using cardiac magnetic resonance navigator gated high temporal resolution tissue phase mapping. Methods: LV motion patterns, myocardial velocities and time-to-peak values for radial, rotational and longitudinal motion were obtained in 19 patients with triple vessel CAD and in a group of 9 age-matched healthy subjects. Radial, circumferential and longitudinal velocity curves were recorded separately for 16 ventricular segments. Ventricular torsion rate and longitudinal strain rate were also derived for each group. Results: Markedly reduced peak diastolic longitudinal velocities (-7.9 ± 0.6 versus-14.1 ± 1.1cm/s) and peak diastolic longitudinal strain rates (1.1 ± 0.2 versus 2.7 ± 0.1s-1) were the most prominent findings in CAD. Patients with CAD also demonstrated lower peak radial velocities, the difference increasing towards the LV apex (peak systolic values of 3.1 ± 0.2 versus 3.5 ± 0.2cm/s at the LV base and 2.4 ± 0.2 versus 3.5 ± 0.2cm/s at the LV apex), with sub-endocardial myocardium being affected to a greater extent. Prominent changes in rotational velocities and an altered pattern of ventricular rotation were also noted in CAD patients. Conclusion: The study revealed complex alterations in radial, rotational and longitudinal LV wall motion in patients with CAD. Peak diastolic longitudinal velocity at the LV base and peak diastolic longitudinal strain rate seem particularly useful for detecting early changes in LV dysfunction associated to CAD. Evaluation of the pathophysiological interplays and underlying mechanisms of these changes require further studying and can provide new insights into understanding the pathophysiology of CAD.
