Key result
Multimodality imaging accurately reveals AR anatomy and mechanisms in a rare UAV matching surgical findings.
Why the study?
Unicuspid aortic valve presenting as predominant severe aortic regurgitation is rare and challenging to diagnose accurately over time.
Multimodality imaging is effective in accurately diagnosing the rare presentation of unicuspid aortic valve with severe aortic regurgitation.
Answers are grounded in this paper and cite their sources.
UAV merits consideration in unexplained severe AR with diagnostic delay; supports multimodality imaging utility but leaves open broader applicability.
Unicuspid aortic valve (UAV) presented as predominant severe aortic regurgitation (AR) is rare (<1%) in pure AR cohort. We present a case with UAV that took more than 1 decade to achieve accurate diagnosis. Multimodality imaging showcased precise anatomy of UAV and mechanisms of AR, resembling exactly the surgical findings. (Level of Difficulty: Intermediate.)
