成人法洛四联症修复后肺动脉瓣置换术的时机仍有争议。对17例成人法洛四联症修复患者的磁共振成像研究显示，右心室（RV）容积显著减少（右室舒张末期容积163 +/- 34至107 +/- 26 ml/m2，p < 0.001;肺动脉瓣置换术后平均随访21个月时，右心室收缩末期容积为109 +/- 27至69 +/- 22 ml/m2，p < 0.001）;而RV收缩功能保持不变（平均RV射血分数32 ± 7%至34 ± 10%，p = 0.12）。在肺动脉瓣置换术前右心室舒张末期容积> 170 ml/m2或右心室收缩末期容积> 85 ml/m2的患者中，没有一个在手术后右心室容积“正常化”。(c)2005年，Excerpta Medica Inc.
The timing of pulmonary valve replacement in adult patients with repaired tetralogy of Fallot remains controversial. A magnetic resonance imaging study in 17 adult patients with repaired tetralogy of Fallot reveals a statistically significant decrease in right ventricular (RV) volume (RV end-diastolic volume 163 +/- 34 to 107 +/- 26 ml/m(2), p < 0.001; RV end-systolic volume 109 +/- 27 to 69 +/- 22 ml/m(2), p < 0.001) at a mean follow-up of 21 months after pulmonary valve replacement; whereas RV systolic function remained unchanged (mean RV ejection fraction 32 +/- 7 % to 34 10 %, p = 0.12). In no patients with a RV end-diastolic volume > 170 ml/m(2) or a RV end-systolic volume > 85 ml/m(2) before pulmonary valve replacement were RV volumes "normalized" after surgery.
