Key result
Papillary muscle-splitting myotomy relieves massive tricuspid regurgitation in infant tricuspid valve dysplasia.
Why the study?
Tricuspid valve dysplasia with massive and restrictive tricuspid regurgitation due to abnormal papillary muscle and shortened chordae in infants requires effective surgical treatment strategies.
Does a papillary muscle-splitting technique improve tricuspid regurgitation in an infant with tricuspid valve dysplasia?

Does a papillary muscle-splitting technique improve tricuspid regurgitation in an infant with tricuspid valve dysplasia?
A papillary muscle-splitting technique via myotomy can be a successful surgical approach for treating tricuspid valve dysplasia in young infants.

May support papillary muscle-splitting myotomy in rare infant tricuspid dysplasia; leaves open generalizability beyond this single case.
We describe a 3-month-old girl who presented with massive and restrictive tricuspid regurgitation due to shortened chordae attached to an abnormal papillary muscle. The condition was improved by myotomy, which resulted in papillary muscle-splitting technique. We successfully treated tricuspid valve dysplasia in a young infant using a rare procedure based on a thorough understanding of the heart's morphologic features.

Katayama et al. (2023) conducted a case report in Tricuspid valve dysplasia (n=1). Myotomy (papillary muscle-splitting technique) was evaluated on Improvement of condition. Myotomy using a papillary muscle-splitting technique successfully improved massive and restrictive tricuspid regurgitation in a 3-month-old girl with tricuspid valve dysplasia.
