A separate dataset of 27 906 studies from UCSF was used to train a second multi-view DNN model to detect moderate-to-severe or severe MR using colour Doppler in the same views. External validation was performed on echocardiographic MVP videos from Houston Methodist Hospital. The DNN model for MVP detection achieved an area under the receiver operating characteristic curve (AUC) of 0.917 [95% confidence interval (CI): 0.899\u20130.934], with stronger performance in those with mitral annular disjunction (MAD) or bileaflet MVP. External validation for MVP detection in a geographically and demographically distinct population yielded an AUC of 0.835 (95% CI: 0.803\u20130.869). The DNN for detection of moderate-to-severe or severe MR in patients with concurrent MVP achieved an AUC of 0.877 (95% CI: 0.805\u20130.939).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Artificial intelligence algorithms can perform automatic detection of MVP and clinically significant MR from echocardiogram studies with high performance.

These algorithms could provide a novel approach for automated, accurate, and rapid diagnosis of MVP and its common clinical sequelae across institutions.<\/jats:p>\n
