# Description
This model is a [MedRoBERTa.nl](https://huggingface.co./CLTL/MedRoBERTa.nl) model finetuned on Dutch echocardiogram reports sourced from Electronic Health Records.
The publication associated with the span classification task can be found at https://arxiv.org/abs/2408.06930.
The config file for training the model can be found at https://github.com/umcu/echolabeler.
# Minimum working example
```python
from transformer import pipeline
```
```python
le_pipe = pipeline(model="UMCU/Echocardiogram_MitralRegurgitation_reduced")
document = "Lorem ipsum"
results = le_pipe(document)
```

</details>
Note: `lv_dias_func` should have been `dias_func`..
# Intended use
The model is developed for *document* classification of Dutch clinical echocardiogram reports.
Since it is a domain-specific model trained on medical data, it is **only** meant to be used on medical NLP tasks for *Dutch echocardiogram reports*.
# Data
The model was trained on approximately 4,000 manually annotated echocardiogram reports from the University Medical Centre Utrecht.
The training data was anonymized before starting the training procedure.
