Neonatal Mitral and Tricuspid Valve Repair for In Utero Papillary Muscle Rupture

Surgical repair of critical neonatal tricuspid and mitral insufficiency associated with papillary muscle or chordal rupture is feasible and can result in good early and midterm results. Our modification of the De Vega annuloplasty technique with the ability to externally adjust the size of the annulus under echocardiographic guidance may improve the accuracy of the repair in the neonate.
