Abstract

INTRODUCTION: To externally validate an FDA-approved artificial intelligence (AI) tool for detecting heart failure with preserved ejection fraction (HFpEF) using echocardiographic video clips, comparing its performance to invasive haemodynamic criteria in a real-world referral cohort with unexplained dyspnoea. METHODS: We retrospectively analysed 47 patients who underwent transthoracic echocardio…
