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.\n2. 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.\n3.
