Objective
Mitral annular plane systolic excursion (MAPSE) is a simple way to evaluate—left ventricle (LV) function. Our aim was to explain the relationship of MAPSE with LV function and biochemical markers in patients with preserved ejection fraction (EF), and to determine whether it has an effect on prognosis in echocardiography (echo) practice.
Methods
Consecutive patients referred to the echo laboratory between November 2020 and March 2021 were included in the study. In addition to conventional parameters, MAPSE of the lateral mitral annulus was measured in all patients. Patients were divided into three groups according to lateral MAPSE: low (<12 mm), relatively preserved (12–15 mm), and high (≥15 mm).
Results
A total of 512 patients with preserved EF were included in the study. MAPSE was low in 44 patients (9%), relatively preserved in 231 patients (45%), and high in 237 patients (46%). The mean age was higher in the low group compared to the other two groups (p < 0.001) and the body mass index was increased in the low group compared to the high group (p = 0.010). Atrial fibrillation and hypertension were more common in patients with low MAPSE. The rate of diastolic dysfunction (DD) and all‐cause hospitalization were higher in the low and relatively preserved groups than in the high group (p < 0.001, p = 0.002; respectively). The pro‐BNP level and mortality rate were higher in the low group compared to the relatively preserved and high groups (p = 0.007, p = 0.005; respectively). MAPSE was identified as independent predictor of hospitalization (OR: 0.284, 95% CI: 0.093–0.862, p = 0.026) via multivariate analysis and independent predictor of in‐hospital mortality (HR: 0.002, 95% CI: 0–0.207, p = 0.008).
Conclusions
Analysis of LV longitudinal function by echo‐derived lateral MAPSE when LV ejection fraction is normal provides important information about DD and related heart failure and may predict prognosis in echo practice.
Objective: In this study, we aimed to compare the functional adaptations of the left ventricle in variant forms of left ventricular hypertrophy (LVH) and to evaluate the use of two-dimensional speckle tracking echocardiography (2D-STE) in differential diagnosis and prognosis. Methods: This was a prospective cohort study of 68 patients with LVH, including 20 patients with non-obstructive hypertrophic cardiomyopathy (HCM), 23 competitive top-level athletes free of cardiovascular disease, and 25 patients with hypertensive heart disease (HHD). All the subjects underwent 2D transthoracic echocardiography (TTE) and 2D-STE. The primary endpoint was all-cause mortality. Global longitudinal strain (GLS) below −12.5% was defined as severely reduced strain, −12.5% to −17.9% as mildly reduced strain, and above −18% as normal strain. Results: The mean LV-GLS value was higher in athletes than in patients with HCM and HHD with the lowest value being in the HCM group (HCM: −11.4±2.2%; HHD: −13.6±2.6%; and athletes: −15.5±2.1%; p<0.001 among groups). LV-GLS below −12.5% distinguished HCM from others with 65% sensitivity and 77% specificity [area under curve (AUC)=0.808, 95% confidence interval (CI): 0.699-0.917, p<0.001]. The median follow-up duration was 6.4±1.1 years. Overall, 11 patients (16%) died. Seven of these were in the HHD group, and four were in the HCM group. The mean GLS value in patients who died was −11.8±1.5%. LV-GLS was significantly associated with mortality after adjusting age and sex via multiple analysis (RR=0.723, 95% CI: 0.537-0.974, p=0.033). Patients with GLS below −12.5% had a higher risk of all-cause mortality compared with that of patients with GLS above −12.5% according to Kaplan-Meier survival analysis for 7 years (29% vs. 9%; p=0.032). The LV-GLS value predicts mortality with 64% sensitivity and 70% specificity with a cut-off value of −12.5 (AUC=0.740, 95% CI: 0.617-0.863, p=0.012).
Conclusion:The 2D-STE provides important information about the longitudinal systolic function of the myocardium. It may enable differentiation variable forms of LVH and predict prognosis.
Factor V Leiden mutation is commonly associated with venous thromboembolism. Although there are cases reported with prosthetic valve thrombosis, no native valve thrombosis has been reported in the literature. In this case report, we presented the concomitant aortic valve thrombosis and sinus of Valsalva aneurysm in a patient with a Factor V Leiden mutation. To the best of our knowledge, our case is the first in the literature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
