MIMIC-IV-ECHO: Echocardiogram Measurements and Images

206,488 echocardiogram studies from 91,372 patients provide structured cardiologist-recorded measurements of heart function, chamber sizes, and valvular morphology. The data includes over 500,000 DICOM image files from 7,243 studies, representing sequences of heart views. This module from MIT's MIMIC-IV project matches echocardiogram records to a clinical database for patients admitted between 2008 and 2022.

Use Cases

• Training models for automated measurement of chamber sizes and volumes from echocardiogram images.
• Developing algorithms to assess systolic and diastolic function based on structured hemodynamic data.
• Linking echocardiographic findings to clinical outcomes using the matched MIMIC-IV Clinical Database.
• Analyzing valvular morphology and function patterns across a large patient cohort.
• Researching temporal trends in echocardiographic measurements from 2008 to 2022.

Strengths

• 206,488 echocardiogram studies provide a substantial volume of structured measurements.
• Data is matched to the MIMIC-IV Clinical Database, enabling rich cross-module analysis.
• Includes over 500,000 DICOM image files, offering a multimodal resource.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The DICOM image subset is from a specific, narrower time range (2017-2019) and patient cohort.
• Unstructured measurements from free-text reports are noted as unavailable in this module.
