Task: Answer Verification
Input (English): Question: Are symptoms in severe aortic stenosis associated with decreased compensatory circumferential myocardial mechanics?
Answer: Longitudinal strain was uniformly low in patients with severe AS and lower in those with symptoms. Compensatory circumferential myocardial mechanics (increased apical circumferential strain and rotation) were absent in symptomatic patients. Thus, myocardial mechanics may help in the follow-up of patients with severe AS and timing of valve surgery.
Output (English): yes
