Pulmonary hypertension persisted in a 57-year-old man after mitral and tricuspid valve replacement to treat mitral and tricuspid regurgitation. Heart failure gradually worsened after surgery. Pulmonary hypertension was initially considered as the major reason for the heart failure, and inhaled nitric oxide was administered. Thereafter, the heart failure improved and mechanical circulatory assist could have been avoided. We believe that inhaled nitric oxide is a less invasive and effective method for improving pulmonary hypertension and hemodynamics after mitral valve replacement.
