Abstract Funding Acknowledgements Type of funding sources: None. Introduction The hemodynamic definition pulmonary hypertension (PH) has been updated, with lowering the mean arterial pressure (mPAP) threshold from 25 to 20 mmHg according new 2022 ESC/ERS Guidelines. Although there is no single echocardiographic parameter that reliably informs about PH status, some parameters cut-offs remained same, including a peak tricuspid regurgitation velocity (PTRV) >2.8m/s. potential underdiagnosis not evaluated. Objectives To evaluate screening power standard detect guidelines and establish predictors. Methods A prospective registry consecutive intermediate-high- high-risk PE pts submitted CDT in tertiary center was used. 3 months after procedure, patients were right heart catheterization echocardiogram screen chronic thromboembolic (CTEPH). According criteria, divided two groups, analyzed regarding their predictive power. ROC curve analysis performed optimal predicting guidelines. Results 17 (60% women, age 59 ± 16 years) included. Among these, 7 (41,2%) diagnosed pre-capillary by RHC at follow-up. parameters, PTRV (p 0.015), presence (0.034) ventricle-pulmonary artery (RV-PA) coupling 0.041) significantly different between groups (Fig 1 A). Other such as ventricle dilation 0.849), TAPSE 0.100), annular s’ 0.646), outflow tract acceleration time 0.229) pericardial effusion 0.849) did show significant differences. Regarding PTRV, revealed an cut-off 2.6 m/s (pressure gradient 27mmHg) our population (AUC 0.911, p 0.030, Sn 71.4%, Sp 100%), compared conventional 2.8 31 mmHg) 0.470, 28.6%, 100%). use > allows reduce false negatives without losing specificity B, C D). Conclusion With recent update leads population. Lowering seems increase sensitivity, specificity. seem predict accurately PH.

Evaluation of Advanced Echocardiographic Parameters of Right Ventricular in Patients with Pulmonary Hypertension
Background and Objective: Pulmonary hypertension is an increase in blood pressure of the pulmonary artery which leads to right ventricular dysfunction. Therefore, the present study aimed to compare echocardiographic parameters in the study of right ventricular failure in patients with pulmonary hypertension. Materials and Methods: In the present descriptive cross-sectional study, data were col...
متن کاملCan we Rely on SQL?
It is important for any data language that it enables many people to derive correct information from a databases in a simple, effective way with predictable performance. In an analysis is shown that SQL cannot fulfill these essential preconditions. It is caused by insufficient structural semantics of the relational model and the related operations in SQL. This follows from a comparison with res...
متن کاملChronic thromboembolic pulmonary hypertension: do we need a new definition?
Chronic thromboembolic pulmonary hypertension (CTEPH) is the end result of persistent obstruction of the pulmonary arteries following episodes of acute and/or recurrent pulmonary emboli [1]. Pulmonary hypertension probably stems from a smaller pulmonary arterial cross sectional area due to thrombus organisation and a redistribution of blood flow through the patent pulmonary arterial bed produci...
متن کاملThe new definition of pulmonary hypertension.
D espite the progress that has been made in the field of pulmonary hypertension (PH) [1–3], there is no unifying and globally accepted definition of the condition. The first official haemodynamic definition of PH was proposed at the First World Symposium on Pulmonary Hypertension which took place 1973 in Geneva, Switzerland as a World Health Organization (WHO)-sponsored meeting [4]. This confer...
