Area of Science:

  • Cardiology
  • Artificial Intelligence
  • Medical Imaging

Background:

  • Right ventricle (RV) abnormalities require improved diagnostic algorithms.
  • Current diagnostic methods for RV abnormalities are insufficient.
  • AI offers potential for enhanced cardiac diagnosis.

Purpose of the Study:

  • To develop and validate a deep learning algorithm for detecting RV abnormalities.
  • To compare the AI algorithm's performance against machine learning models and human experts.
  • To explore the use of nomograms for assessing patient disease risk.

Main Methods:

  • Utilized the Automated Cardiac Diagnosis Challenge dataset with 40 subjects (20 with RV abnormalities, 20 normal).
  • Trained a deep learning neural network and six machine learning algorithms.
  • Validated the model against 8 MRI specialists and evaluated performance using AUC, accuracy, recall, sensitivity, and specificity.

Main Results:

  • The deep learning algorithm achieved an AUC of 1 (95% CI: 1-1) in both training and validation groups.
  • The AI algorithm outperformed six machine learning algorithms and 87.5% of human experts.
  • A nomogram model demonstrated ability to assess disease risk within a range of 0.2-0.8.

Conclusions:

  • A deep learning algorithm can effectively identify patients with RV abnormalities.
  • This AI tool has the potential to improve the detection and timely diagnosis of RV diseases across care levels.
  • This study is the first to validate an AI algorithm for RV abnormalities against human expert performance.
