Abstract Background Aortic regurgitation (AR) has an important impact on myocardial mechanics and recent studies have proved the value of global longitudinal strain (GLS) in assessment its severity prognosis. Our purpose was to assess if direct regurgitant jet wall could affect regional strain. Methods Eighty patients with chronic moderate/severe AR were retrospectively studied. Patients considered a jet-related reduction when segments directly impacted by had their reduced at least 30%...
Proportionality of secondary mitral regurgitation (sMR) may be a key factor in deciding whether patient benefit from intervention. The aim this study was to evaluate the prognostic value two different concepts proportionality and assess their ability improve MR stratification proposed by American Society Echocardiography (ASE) guidelines.We conducted retrospective analysis patients with reduced left ventricular ejection fraction (LVEF) (<50%) at least mild sMR. status calculated using...
Abstract Background The estimation of pretest probability (PTP) is a key step when evaluating patients with suspected coronary artery disease (CAD). Current European guidelines recommend using an algorithm based on age, sex, and symptom typicality. However, many cardiologists do not regularly use this method, relying instead overall clinical impression. aim study was to compare algorithmic prediction obstructive CAD in set symptomatic chronic syndrome (CCS). Methods In survey study, 10 from...
Abstract Background Chemotherapy-induced cardiotoxicity is a serious complication often leading to heart failure. While the left ventricle (LV) has been thoroughly implicated in this process, data scarce on right ventricular (RV) function following cardiotoxic chemotherapies. Our goal was determine prevalence and clinical significance of RV dysfunction cohort patients who had received these drugs. Methodology Single-center retrospective study cancer performing 2D transthoracic echocardiogram...
Abstract Funding Acknowledgements Type of funding sources: None. Background Aortic regurgitation (AR) has been shown to have an impact on myocardial mechanics and recent studies proved the value global longitudinal strain (GLS) as additional parameter in assessment disease severity prognosis. However, a direct localized influence regurgitant jet (RJ) regional deformation not yet demonstrated. Purpose To assess if there is pattern (LS) impairment AR connected direction RJ, well its potential...
Abstract Introduction Mitral balloon valvuloplasty (MBV) is the guideline recommended treatment for symptomatic severe mitral stenosis (MS) with suitable anatomy, but often deemed transitory. However, data on very-long term echocardiographic follow-up scarce. The aim of our study was to describe clinical and outcomes in patients previously submitted MBV rheumatic MS. Methods We conducted a single-centre retrospective enrolling MS from 1990 until 2021. Follow-up considered last registered...
Abstract Background Functional mitral regurgitation (fMR) severity grading by 2D transthoracic echocardiography (TTE) can be a complex task, especially in patients where PISA assumptions are not met (eg. non-circular orifice or multiple jets). Cardiac magnetic resonance (CMR) provide further insight on the hemodynamic burden of fMR accurately determining regurgitant fraction (RegFrac). Our goal was to investigate concordance and disagreement between two modalities assessing fMR. Methodology...
