Unsupervised k-means clustering of serial lactates (baseline, 4 hours, 24 hours) defined four metabolic phenotypes.

Computational fluid dynamics simulations were used to quantify aortic root washout, washout progression, and perform platelet tracking to evaluate thrombogenic potential. Results showed that when the aortic valve (AV) was closed, only 60% of blood was washed out after 4 seconds, whereas AVO significantly increased washout efficiency, clearing over 80% of blood within 3 seconds. Platelet tracking revealed that platelets were up to 60% more likely to stagnate for a nonfunctional AV compared with transaortic flow scenarios. Higher transaortic flow had the lowest thrombogenic potential score. These findings demonstrate that transaortic valve flow is the primary factor driving aortic root washout.
