aceCURL-AID: Automated Echocardiographic Motion Analysis for Quantitative Assessment of Posterior Systolic Curling
Objective Posterior systolic curling (PSC) is a morphofunctional abnormality of the posterior mitral annulus associated with malignant ventricular arrhythmias and sudden cardiac death. Current diagnosis is qualitative and operator-dependent, limiting reproducibility, objectivity and standardization. This study introduces CURL-AID (Curling Ultrasound-based Recognition and Labeling-Automated Intelligence-driven Diagnosis), a fully automated echocardiographic framework for PSC detection through quantitative analysi…
CURL-AID automated analysis of parasternal long-axis echocardiograms quantified posterior annular hypermobility and classified posterior systolic curling with AUC 0.865 and accuracy 0.82.
Findings are based on 100 retrospectively collected parasternal long-axis echocardiograms with internal nested cross-validation and no reported external validation or prospective testing.

How to verify without trusting this page
Fetch the canonical text of any version from /api/record/TRV-2026-0759 and hash it yourself — for example shasum -a 256 on the saved canonical field. The result must equal content_hash, and each version’s text ends with prev:followed by the prior version’s hash (version 1 chains to 64 zeros). If a single character of any version had been altered since certification, the chain would not reproduce.
