Valve repair for tricuspid papillary muscle rupture late 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.
• Typically, rupture affects the mitral valve, leading to mitral regurgitation.
• Tricuspid regurgitation secondary to papillary muscle rupture, especially after right ventricular infarction, is exceptionally uncommon.

Observation:

• A 70-year-old male developed massive tricuspid regurgitation.
• This complication occurred after percutaneous coronary intervention for a right coronary artery stent.
• The cause was identified as papillary muscle rupture.

Findings:

• The patient underwent successful tricuspid valve repair.
• The surgical technique involved reimplanting the native papillary muscle in situ.
• No artificial chordae or prosthetic valves were utilized in the repair.

Implications:

• This case presents a unique surgical approach for a rare cardiac complication.
• The successful in situ papillary muscle reimplantation offers a potential alternative to valve replacement.
• Further investigation into this technique may provide new therapeutic options for tricuspid regurgitation.
