MIMIC-IV-ECHO: Echocardiogram Matched Subset

The MIMIC-IV-ECHO module contains structured echocardiographic measurements
and DICOM files from echocardiography exams.

Structured measurements are available from 206,488 echocardiogram studies
(including 179,928 transthoracic, 16,389 stress, and 10,171 transesophageal
echocardiograms). These are from 91,372 unique patients who are in the MIMIC-
IV Clinical Database and who had echocardiograms conducted between 2008 -
2022\. The dataset encompasses a broad range of cardiologist-recorded
echocardiographic measurements, including chamber sizes and volumes, systolic
and diastolic function, valvular morphology and function, aortic root and
great vessel dimensions, and Doppler-derived hemodynamics. Unstructured
measurements are present in the cardiologist's free-text reports, which will
be made available later under the MIMIC-IV-Note module.

The echocardiogram DICOMs contain more than 500,000 DICOMs across 7,243
studies from 4,579 distinct patients. This subset contains transthoracic
echocardiograms for patients who appear in the MIMIC-IV Clinical Database and
were admitted between 2017-2019\. A given study consists of numerous sequences
of images, with each sequence representing a particular view of the patient's
heart.

Records in MIMIC-IV-ECHO are matched to the MIMIC-IV Clinical Database, making
it possible to link to information across the MIMIC-IV modules. We have also
provided information for linking the DICOMs to the structured measurements and
notes where available.

MIMIC-IV-ECHO 模块（MIMIC-IV-ECHO module）收录了来自4579名独立患者的7243项检查，共计超过50万份超声心动图（echocardiograms）。每项检查包含多组图像序列，每组序列对应患者心脏的某一特定视图。本子集收录了出现在MIMIC-IV临床数据库（MIMIC-IV Clinical Database）中、且入院时间介于2017年至2019年的患者的超声心动图。我们已提供可将指定超声心动图与可用的心脏病学医师报告相关联的信息。MIMIC-IV-ECHO中的记录已与MIMIC-IV临床数据库完成匹配，可实现跨MIMIC-IV各模块的信息关联。

背景与挑战

背景概述

MIMIC-IV-ECHO是一个包含超过50万张超声心动图影像的数据集，源自4,579名在2017年至2019年间入院患者的7,243项研究。该数据集与MIMIC-IV临床数据库匹配，允许链接患者临床信息，且数据已去标识化以满足隐私要求，主要用于心脏疾病的研究和分析。
