title: Concurrent balloon dilatation of mitral and tricuspid stenosis during pregnancy using an Inoue balloon.
abstract: Percutaneous balloon dilatation of combined mitral and tricuspid stenoses was performed successfully in a 22-year-old woman during the 23rd week of pregnancy, using an Inoue balloon catheter. Following valvuloplasty, mean transmitral gradients decreased from 36 to 5 mmHg and the mean transtricuspid gradients from 12 to 3 mmHg. The procedure was uncomplicated and well tolerated, leading to the vaginal delivery of a healthy newborn at term. The fluoroscopy time required was 84 s for mitral and 18 s for tricuspid valvuloplasty. The present report highlights the advantage of the Inoue balloon catheter for multivalvular dilatation during pregnancy with minimum fluoroscopy time.
