Key result
Advanced echocardiography identified a rare true trileaflet mitral valve as an unusual contributor to mitral regurgitation in a patient with hypertrophic cardiomyopathy.
Case Report (n=1)
No
A trileaflet mitral valve is a rare anatomical variant that can contribute to mitral regurgitation in patients with hypertrophic cardiomyopathy.
May aid recognition of rare mitral variants on routine echo; leaves open prevalence and clinical impact.

Nalawade et al. (2023) conducted a case report in Hypertrophic cardiomyopathy with mitral regurgitation (n=1). Trileaflet mitral valve was evaluated on Identification of mitral valve anatomy and cause of regurgitation. Advanced echocardiography identified a rare true trileaflet mitral valve as an unusual contributor to mitral regurgitation in a patient with hypertrophic cardiomyopathy.
