AI ECHO INSIGHT RCT for Automated Echo Reporting

The goal of this blinded randomized controlled trial is to assess whether AI-assisted TTE interpretation can improve cardiologist efficiency and reduce interpretation variability while preserving accuracy compared to current methods in adult patients whose historical echocardiogram images were performed. The main questions it aims to answer is to: 1. Assess overall transthoracic echocardiogram (TTE) interpretation accuracy of an AI-assisted workflow compared to standard cardiologist-only and sonographer-assisted workflows to hypothesize if AI-assisted workflow for echocardiography interpretation is non-inferior in accuracy compared to standard workflows. 2. Evaluate cardiologist interpretation time using an AI-assisted workflow compared to standard cardiologist-only and sonographer-assisted workflows to determine if an AI-assisted workflow will result in a decrease in interpretation time compared to the cardiologist-only workflow. 3. To compare interpretation consistency and reliability compared to historical reports as well as consensus reports of all finalized cardiologist reports.

The Echodynamic Approach

The aim of this prospective observational study is to assess the accuracy of non-invasive hemodynamic parameter estimation via trans-thoracic echocardiography (TTE) compared to the invasive gold standard of right heart catheterization (RHC). This study will include patients who undergo both TTE and RHC on the same day, under the same hemodynamic conditions. The primary research question is: how does the echodynamic evaluation perform compared to right heart catheterization?

The FUnctional TricUspid REgurgitation by 3D EChocardiography Cooperative Study

Prospective, multicenter, observational study to enroll consecutive patients with functional tricuspid regurgitation (FTR) with the primary aim to: * Use patients' outcomes as a reference to try to define the threshold values for the different grades of FTR severity; and secondary aims to: * Use 3D echocardiography to assess the relationships among the geometry (size and shape) of the right ventricle, right atrium, tricuspid annulus, and tricuspid leaflets according to the underlying cardiac condition (i.e., atrial fibrillation, pulmonary hypertension, right ventricular cardiomyopathy, congenital heart diseases, etc.) * Assess the accuracy, and incremental diagnostic and prognostic value of a new software package to measure tricuspid annulus and valve geometry * Develop new parameters of FTR severity that take into account the lower momentum of the tricuspid regurgitant jet (compared with the mitral regurgitation jet), the complex anatomy of the regurgitant orifice, and both the intra-beat and respiratory variation of the regurgitant volume * Test the hypothesis that there is no actual grading but a continuum of increased risk of adverse outcome with the increase of FTR severity, and we need robust quantitative metrics (for example, the regurgitant fraction - currently not included in guidelines - which takes into account the right ventricular volume and function) more than grading schemes to assess the severity of the diseases and the effect of treatments * Test the hypothesis that the relationship between FTR severity and the outcome may be different according to the underlying cardiac condition (i.e., atrial fibrillation, pulmonary hypertension, right ventricular cardiomyopathy, congenital heart diseases, post-cardiac surgery, etc.) as this will affect the timing for interventions
