AI calcium scoring on 3D transesophageal echo correlates with CT in aortic stenosis

AI-based calcium quantification from 3D transesophageal echocardiography (TEE) showed significant correlation with CT Agatston score (r=0.65) and AUC 0.87 for severe calcification in a prospective pilot of 23 patients with aortic stenosis.

• Prospective pilot study in 23 patients with moderate or severe aortic stenosis comparing AI-derived TEE calcium score to CT Agatston score.
• For identifying severe calcification, a cutoff of 68,813 pixels yielded sensitivity 89.5% and specificity 75.0%.
• Small sample size (N=23) and pilot design limit generalizability; no external validation.
