MIMIC IV Echo Data

[JBarsotti]

Description

You all are doing wonderful work with MIMIC! My collaborators are cardiologists and would be interested in getting their hands on MIMIC-IV-ECG. I know it comes out in August but also know that it is available to the consortium members. I was just wondering whether there is a process to become a consortium member and whether it is worth it.

Thanks!

You can reach out to consortium@physionet.org for more detail and those responsible for the consortium will get back to you I'm sure.

Thank you! I am working on a presentation using your MIMIC data right now. :)

Hi, my colleagues and I are currently looking at the MIMIC-IV echocardiogram dataset. We are trying to use the echocardiogram data and linking it to the MIMIC-IV Note. It is mentioned that the note will be made available on the MIMIC-IV Note for the studies that have note_id within the ‘study_list.csv’. However, upon examination on the MIMIC-IV Note ‘radiology.csv’ dataset, we did not find any linked report to the note_id within the echocardiogram dataset. We did find some echocardiogram descriptions within the ‘discharge.csv’ dataset in a form of discharge summaries.

Thus, is the cardiology report for the dataset has not been made available within the MIMIC-IV note? Or is the one within ‘discharge.csv’ would be the echo report?

Thank you!

@emiramaro , the cardiologist notes for a given Echo have not been released yet. We are working on getting those released, hopefully it'll be sooner than later.

@michelleespranita , we are preparing the release of the structured measurements now. They should be available by the end of the year. The free text notes will not be released at this time though.

hi @briangow, I'd like to inquire about the release plan of the cardiovascular notes for a given echo. Will it be in the first half of 2026? Thank you for providing this valuable resource!

Hi @briangow I am also interested to follow up reagrding the release of structured measurements for this cohort. Thank you, Sam Kleman

Hi @briangow, I would like to follow up regarding the structured measurements. Are there any plans to release them soon? Thank you in advance!

I am also keen to follow-up @briangow

Hello, I am working with the MIMIC-IV Echocardiogram dataset. However, I am unable to find out how exactly the different views within the dataset are represented. I could not find metadata within the dicom files suggesting what probe position/angle view number _XXXX corresponds to. Moreover, do the view numbers between different patients correspond to the same probe position/angle (i.e., do all views _0001 represent the same probe position across all patients? Any help would be greatly appreciated!

[Rapuris]

Following back up. Any advice would be greatly appreciated!

[briangow]

@Rapuris , sorry for the late reply. The Echo metadata doesn't contain information regarding the probe position/angle for a given view. The view numbers also do not necessarily correspond to a particular probe position/angle.

We are hoping to release a derived dataset at some point which uses ML to classify the view information.

@briangow Thank you for the update! As of now, is there any way to distinguish between the videos/frames in the study (as to type of ultrasound imaging, view, etc.)? I assume not, but I want to confirm. I'm looking forward to the derived dataset as well. Any estimation of when that is coming out?

The structured measurements have been released in v1.0 of the project.
