[Mitral regurgitation associated with Wegener's granulomatosis]

Area of Science:

• Rheumatology
• Cardiology
• Pathology

Background:

• Wegener's granulomatosis (WG) is a rare autoimmune necrotizing vasculitis affecting multiple organ systems.
• Commonly involves respiratory tract and kidneys; cardiac involvement is infrequent.
• Cardiac valvular disease is a rare manifestation of WG.

Observation:

• A patient presented with severe WG and grade 4 mitral insufficiency.
• Surgical mitral valve analysis revealed leaflet perforation without endocarditis.
• Pathology showed myxoid degeneration; cultures were negative.

Findings:

• Mitral valve perforation due to WG, despite rarity, can occur.
• Valve replacement was a viable surgical option for this patient.
• The patient recovered well six months post-operation.

Implications:

• Cardiac involvement in WG requires thorough cardiologic evaluation.
• Early diagnosis and management of cardiac manifestations are crucial for patient outcomes.
• This case underscores the diverse cardiac presentations of WG.
