对术后存活的２９３例及未手术２１例先天性心脏病（先心病）合并重度肺动脉高压患者随诊０．７７年～１７．０３年，平均７．３１年。肺动脉高压临床Ⅰ、Ⅱ级手术效果优良；Ⅲ、Ⅳ级患者术后１、３、５年生存率分别为１００％、８２．９％、７７．９％，症状缓解率分别为１００％、８０．６％、６０．３％，在各时点上的生存率和总的生存期均显著低于同期未手术的同级患者。对肺动脉高压临床分级的科学性及可行性进行再讨论，并重申严格掌握“临界性”肺动脉高压患者的手术适应证。
293 cases of postoperative survival and 21 cases of non-surgical congenital heart disease (congenital heart disease) with severe pulmonary hypertension were followed up from 0.77 to 17.03 years, an average of 7.31 years. The clinical outcomes of grade Ⅰ and Ⅱ pulmonary hypertension were excellent. The 1, 3 and 5-year survival rates of grade Ⅲ and Ⅳ were 100%, 82.9% and 77.9% respectively, and the rates of remission were 100% and 80% respectively .6% and 60.3% respectively. The survival rates and overall survival at all time points were significantly lower than those of the same grade without surgery in the same period. Further discussion of the scientific and feasibility of clinical classification of pulmonary hypertension, and reiterated the strict grasp of “critical” pulmonary hypertension in patients with surgical indications.
