Mitral autograft for partial tricuspid valve replacement: a case report

Area of Science:

• Cardiology
• Cardiac Surgery
• Infective Endocarditis

Background:

• Surgical management of tricuspid valve infective endocarditis (TVE) remains controversial.
• Large vegetations and recurrent pulmonary emboli pose significant surgical challenges.

Observation:

• A patient with infective endocarditis affecting both mitral and tricuspid valves presented with large tricuspid valve vegetations (>20 mm) and recurrent pulmonary emboli.
• Surgical intervention was indicated due to the persistent large vegetations and embolic events.

Findings:

• The patient underwent partial tricuspid valve replacement using a mitral autograft and mitral valve replacement with a mechanical prosthesis.
• Postoperative follow-up at 18 months showed the patient in good clinical condition with no residual tricuspid regurgitation.

Implications:

• Mitral autograft replacement presents a viable option for tricuspid valve repair in complex infective endocarditis cases.
• This technique expands the reconstructive possibilities for the tricuspid valve, particularly in the context of infection.
