AORTIC STENOSIS ECHOCARDIOGRAPHIC FOLLOW-UP EXPERT SYSTEM

摘要

An imaging examination analysis method includes receiving a patient data set for a patient including measurements for a set of variables relating to a chronic medical condition, such as aortic stenosis (AS), obtained by an imaging examination of the patient. For one or more future time intervals, a likelihood is generated of a predetermined grade of the chronic medical condition (e.g. likelihood of severe AS grade) for the patient at the future time interval. The likelihood is generated using a classifier trained on training data sets for past patients. A follow-up imaging examination date recommendation is determined based on the likelihoods. An inconsistent measurement for the patient may be identified as a measurement whose value compared with a prior measurement for the same variable is consistent with an improvement in the chronic medical condition of the patient between the time of the prior measurement and a present time.
