Aortic regurgitation (AR) affects global left ventricular mechanics. However, limited literature is available on how it may affect regional longitudinal strain. We present a case where severe AR jet is thrashing the anterior-septal wall and reducing its overall longitudinal performance most likely secondary to increased wall shear stress in diastole. This new insight into patho-physiological process using deformation study may have supplementary impact in decision making for surgical intervention. Transthoracic echocardiography is the primary imaging modality for the assessment of AR as it offers evaluation of severity of AR, aetiology of AR, left ventricular (LV) dilatation, LV systolic function, left ventricular mass, diastolic function and global strain. This case highlights the regional disturbances in longitudinal strain in eccentric AR.

Chronic aortic regurgitation (AR) patients typically remain asymptomatic for a long time. Left ventricular mechanics, namely global longitudinal strain (GLS), has been associated with outcomes in AR patients. The authors conducted a systematic review to summarize and appraise GLS impact on mortality, the need for aortic valve replacement (AVR) and disease progression in AR patients. A literature search was performed using these key terms ‘aortic regurgitation’ and ‘longitudinal strain’ looking at all randomized and nonrandomized studies conducted on chronic aortic regurgitation. The search yielded six observational studies published from 2011 and 2018 with a total of 1571 patients with moderate to severe chronic AR. Only two studies included all-cause mortality as their endpoint. The other studies looked at the association between GLS with AVR and disease progression. The mean follow-up period was 4.2 years. We noted a great variability of clinical, methodological and/or statistical origin. Thus, meta-analytic portion of our study was limited. Despite a relevant heterogeneity, an impaired GLS was associated with adverse cardiac outcomes. Left ventricular GLS may offer incremental value in risk stratification and decision-making.

The oxidative stress state is characterized by an increase in oxygen reactive species that overwhelms the antioxidant defense; we do not know if these pathological changes are correlated with alterations in left ventricular mechanics. The aim was correlating the oxidative stress state with the left ventricular global longitudinal strain (GLS) and the left ventricular end diastolic pressure (LVEDP). Twenty-five patients with essential hypertension and 25 controls paired by age and gender were studied. All of the participants were subjected to echocardiography and biochemical determination of oxidative stress markers. The hypertensive patients, compared with control subjects, had significantly (p<0.05) higher levels of oxidized proteins (5.03±1.05versus4.06±0.63 nmol/mg), lower levels of extracellular superoxide dismutase (EC-SOD) activity (0.045±0.02versus0.082±0.02 U/mg), higher LVEDP (16.2±4.5versus11.3±1.6 mm Hg), and lower GLS (−12% versus −16%). Both groups had preserved ejection fraction and the results showed a positive correlation of oxidized proteins with GLS (r=0.386,p=0.006) and LVEDP (r=0.389,p=0.005); we also found a negative correlation of EC-SOD activity with GLS (r=-0.404,p=0.004) and LVEDP (r=-0.347,p=0.014).
