In an echocardiogram analysis method, a diagnostic code is received or generated for an echocardiogram comprising a set of echocardiogram loops. A plurality of different subsets are selected from the echocardiogram. Each subset consists of one or more echocardiogram loops of the set of echocardiogram loops. For each subset, a confidence score indicating relevance of the subset to the diagnostic code is determined using an artificial intelligence (AI) engine operating on the subset, where the AI engine is trained on historical echocardiograms labeled with diagnostic codes. A relevant group of echocardiogram loops is identified based on the determined confidence scores for the respective subsets indicating relevance of the respective subsets to the diagnostic code. An echocardiogram reading user interface is presented, including displaying the diagnostic code associated with the echocardiogram loops of the relevant group of echocardiogram loops.
