Overview

Supports detailed valve assessment in HOCM with MR; leaves open validation in larger cohorts.

Key Points

  • To evaluate a rare trileaflet mitral valve configuration in a patient with hypertrophic obstructive cardiomyopathy and its surgical implications.
  • Case report of a 68-year-old woman with hypertrophic obstructive cardiomyopathy and trileaflet mitral valve variant.
  • Utilized cardiac magnetic resonance and echocardiography for multimodal imaging assessment.
  • Undertook septal myectomy and bioprosthetic mitral valve replacement after failed medical management.
  • Successful surgical intervention resulted in excellent valve function postoperatively.
  • Patient was discharged on postoperative day ten with stable cardiac function.
  • Identified trileaflet mitral valve configuration as a significant factor in severe mitral regurgitation.

This case highlights a rare trileaflet configuration of the mitral valve contributing to severe mitral regurgitation in hypertrophic obstructive cardiomyopathy, underscoring the importance of detailed anatomical assessment in guiding surgical decision-making.

Cite This Study

Kumar et al. (2026) conducted a case report in Hypertrophic obstructive cardiomyopathy (n=1). Septal myectomy and bioprosthetic mitral valve replacement was evaluated. Septal myectomy and bioprosthetic mitral valve replacement successfully treated severe mitral regurgitation in a patient with hypertrophic obstructive cardiomyopathy and a rare trileaflet mitral valve.
