A 22-yr-old pregnant woman with mitral, aortic, and tricuspid stenosis presented with accelerating dyspnea and shortness of breath at the end of her first trimester. She subsequently underwent percutaneous triple-valve balloon valvuloplasty at 22 weeks of gestation without complications and achieved marked clinical improvement. We conclude that percutaneous triple-valve balloon valvuloplasty represents an alternative treatment for mitral, aortic, and tricuspid stenosis in pregnant women with compromised cardiovascular status who do not wish to terminate their pregnancy.
