Abstract and Introduction

Although percutaneous balloon mitral valvuloplasty is known to be a safe and effective procedure during a singleton pregnancy, its use during a twin gestation is limited to a single report with a poor obstetric outcome. In the case we are reporting, a 29-year-old nulliparous patient with a twin gestation was seen at 24 weeks' gestation with congestive heart failure caused by previously undiagnosed mitral stenosis. She had successful percutaneous balloon mitral valvuloplasty, and two healthy infants were subsequently delivered at 36 weeks' gestation.

Success with percutaneous balloon mitral valvuloplasty for the management of severe mitral stenosis during pregnancy has been amply demonstrated for singleton pregnancies. However, search of the literature yielded only one report in which a woman with a twin gestation had balloon mitral valvuloplasty, resulting in improved maternal condition, but with development of fetal growth restriction, preterm delivery, and neonatal death of both twins.[1] The following is the first report of a successful pregnancy outcome after percutaneous balloon mitral valvuloplasty for severe mitral stenosis complicating a twin gestation.
