A Case of an Infant with Flail Tricuspid Valve Due to Spontaneous Papillary Muscle Rupture: Was Neonatal Lupus the Culprit?

A Case of an Infant with Flail Tricuspid Valve Due to Spontaneous Papillary Muscle Rupture: Was Neonatal Lupus the Culprit?

A 3-month-old infant presented in extremis with a flail tricuspid valve. The authors theorized that the genesis of her papillary muscle rupture was perinatal ischemia compounded by worsening pulmonary valvular stenosis leading to excessive fiber tension. Her underlying diagnosis of autoimmune-mediat...

Zusammenfassung:A 3-month-old infant presented in extremis with a flail tricuspid valve. The authors theorized that the genesis of her papillary muscle rupture was perinatal ischemia compounded by worsening pulmonary valvular stenosis leading to excessive fiber tension. Her underlying diagnosis of autoimmune-mediated heart block with endocardial fibroelastosis and prenatal glucocorticoid steroid treatment represents potentiating factors.
