Özet
Mitral valve surgery was performed in 59 patients with severe pulmonary hypertension (average systolic pulmonary artery pressure 77.1 ± 18.6 mmHg; range 50-115 mmHg) between 1983 and 1990. Thirty-eight patients had been subjected to mitral valve replacement, 16 patients both mitral and aortic valve replacement, and 5 patients had open mitral commissurotomy, with an operative (30 day) mortality of 5.0%. These 3 deaths happened during the early postoperative period. Survivors were followed up for a period ranging from 6 months to 7 years with a mean of 36 months. Four late deaths (7.1%) occurred in patients with valve replacement. Actuarial survival was 93 ± 3% at 5 years, and 90.7 ± 4.4% at 7 years. Right ventricular catheterization was performed on 14 patients a mean of 38 months following operation. Systolic pulmonary artery pressure had decreased from a mean of 77.1 ± 18.6 to 39.7 ± 14.0 mmHg (p<0.001) and 90% of the survivors were in New York Heart Association Glass 1 or II compared to 23.7% preoperatively. The clinical and hemodynamic findings in this series suggest that severe pulmonary hypertension is not a contraindication, and pulmonary hypertension decreases significantly after mitral valve surgery. © 1992, International Heart Journal Association.
