Abstract
BACKGROUND: D-shaped left ventricle (D-LV) is an interesting echocardiographic finding inpulmonary hypertension (PH) and is the result of structural distortion of the interventricularseptum. The eccentricity index (EI) is a quantitative measure used to evaluate the severityof D-LV in patients with increased pulmonary artery pressure (PAP). However, D-LV and EIshave rarely been studied in terms of their association with hemodynamic factors.METHODS: A total of 526 patients with a maximal tricuspid regurgitation velocity (VmaxTR)> 2.8 m/s on echocardiography identified between January 2012 and December 2017 wereenrolled. After exclusion, a total of 289 patients were analyzed. The association between D-LVand hemodynamic factors were analyzed using logistic regression. Furthermore, factors thatimpacted the severity of the D-LV, as defined by EIs, were also analyzed using the multiplelinear regression model.RESULTS: In the multivariate logistic regression model, higher pulmonary artery pressure(PAP, p = 0.001), lower tricuspid annular plane systolic excursion (TAPSE, p = 0.048), andE/E′ (p = 0.017) were found to be significant risk factors for the presence of D-LV. Additionalanalysis with age and body mass index added to independent variables, PAP (p = 0.008),TAPSE (p = 0.028), and age (p < 0.001) were significant risk factors for the presence of D-LV.In patients with D-LV, only E/E′ was independently associated with EIs (R2= 0.666, p < 0.001).CONCLUSIONS: In patients with increased PAP, D-LV is associated with PAP, TAPSE, E/E′, andage. EIs are associated with left ventricular filling pressure, represented as E/E′
