[Mitral valve regurgitation associated with severe pulmonary hypertension successfully treated with nitric oxide gas: report of a case].
A 61-year-old woman with mitral valve regurgitation and pulmonary hypertension, was referred to us for surgical repair. Preoperative left ventriculography showed Sellers IV mitral valve regurgitation and high pulmonary arterial pressure: 103/31 (57) mmHg. The mitral valve was replaced with a phi 27 mm SJM mechanical valve. The postoperative residual pulmonary hypertension was successfully treated with nitric oxide gas, decreased significantly pulmonary arterial pressure, and the postoperative course was uneventful. Based on our experience, we think that nitric oxide gas may prove effective for residual pulmonary hypertension after a cardiac operation.
