successful repair of neonatal tricuspid regurgitation due to papillary muscle rupture: a rare case

Background: neonatal rupture of the chordae of the tricuspid valve with severe regurgitation is scarce and devastating. case report: here, we report the case of a full-term male neonate presented with cyanosis caused by severe tricuspid regurgitation due to anterior leaflet papillary muscle rupture. following initial stabilization by the infusion of prostaglandins e1, successful early repair was achieved. conclusion: early diagnosis of the tricuspid valve papillary muscle rupture is critical, and early surgical repair have a good result during early post-operative period.
