Summary

A rare cystic lymphangioma on the mitral valve caused significant regurgitation and heart failure symptoms in a 62-year-old woman. Surgical removal and valve repair were successful, marking the first reported case of this condition.

Area of Science:

  • Cardiovascular Surgery
  • Pathology
  • Cardiac Oncology

Background:

  • Mitral valve prolapse (MVP) is a common valvular heart disease.
  • Pedunculated masses on heart valves are rare and can cause significant hemodynamic compromise.
  • Cystic lymphangiomas are benign tumors typically found in the lymphatic system.

Observation:

  • A 62-year-old female with a history of mitral valve prolapse presented with dyspnea and palpitations.
  • Echocardiography revealed a pedunculated mass on the anterior mitral valve leaflet causing moderate mitral regurgitation.
  • The mass oscillated between the left atrium and left ventricle during the cardiac cycle.

Findings:

  • The patient underwent successful en-bloc resection of the mass and mitral valve reconstruction.

  • Pathohistological examination confirmed the mass as a cystic lymphangioma originating from the mitral valve tissue.
  • This represents the first documented case of a cystic lymphangioma arising from the mitral valve.

    • Implications:

    • This case expands the differential diagnosis for pedunculated cardiac masses and mitral regurgitation.
    • Highlights the importance of thorough investigation of cardiac masses, even in the presence of known valve disease.
    • Suggests that cystic lymphangiomas, though rare, can occur in cardiac structures, necessitating consideration in surgical planning and pathology.
