Twelve patients who had undergone complete repair of tetralogy of Fallot at ages ranging from 8 to 27 years were studied for exercise tolerance several years later. Work performance ranged from 58 to 130% of that predicted. Increased physiological dead space and alveolar-arterial Po2 difference at exercise suggested pulmonary vascular disease, which was confirmed in 1 patient by pulmonary angiography. Excercise tolerance decreased with increasing age at time of repair, underlining the desirability of early corrective operation.
对12例曾在8至27岁接受法洛四联症完全修复术的患者在数年后进行了运动耐量研究。工作能力范围为预测值的58%至130%。运动时生理死腔增加和肺泡-动脉氧分压差增大提示存在肺血管疾病，1例患者经肺血管造影得以证实。运动耐量随修复时年龄的增加而降低，强调了早期矫正手术的可取性。
