Repair of tricuspid papillary muscle rupture after percutaneous coronary intervention

Area of Science:

• Cardiology
• Cardiac Surgery
• Cardiovascular Research

Background:

• Papillary muscle rupture is a rare but serious complication following myocardial infarction.
• While typically affecting the mitral valve, rupture in the right ventricle's papillary muscle leading to tricuspid regurgitation is exceptionally uncommon.

Observation:

• A 70-year-old male patient presented with massive tricuspid regurgitation.
• This condition was a direct consequence of papillary muscle rupture subsequent to percutaneous stenting of the right coronary artery.

Findings:

• A unique surgical approach was employed for tricuspid valve repair.
• The technique involved reimplanting the papillary muscle in its original position without using artificial chordae or prosthetic valves.

Implications:

• This case presents a potentially new surgical strategy for managing rare tricuspid regurgitation due to papillary muscle rupture.
• The successful outcome suggests the feasibility of this innovative repair technique in similar clinical scenarios.
