Repair of tricuspid papillary muscle rupture after percutaneous coronary intervention.

Papillary muscle rupture is a rare complication after myocardial infarction and almost all cases occur in the mitral valve papillary muscle. Tricuspid regurgitation development after right ventricular myocardial infarction caused by papillary muscle rupture is extremely rare.  In this video tutorial we present a 70-year-old man with massive tricuspid regurgitation caused by papillary muscle rupture after percutaneous stenting of the right coronary artery. We performed tricuspid valve repair with reimplanted papillary muscle in situ using neither artificial chordae nor a prosthetic valve. There are no previous case reports of this surgical repair technique.
