中华医学杂志930749 Morphology of right ventricle and hemodynamics in pulmonary atresia with intact ventricular septum Zhou Aiqing,et al.Shanghai Institute for Pediatric Research,Shanghai 200092
Cardiac catherization and angiographjy were per-formed in 31 patients with PA/IVS to evaluate the morphology of RV and hemodynamics.The age of pa-tients ranged from 1 day to 39 month (mean 4.7 month).The patients were divided into three groups:mild(19.4%),moderate (64.5%) and severe (16.1%) RV hypoplasia,according to the degree of tricuspid valve and right ventricular hypoplasia.Seven of the 31 patients (22.6%) had right ventricular myocardial sinosoid-coronary artery fistula.The right and left ventricular pressures in 26 patients were measured simultaneously.The right ventricular pressures were suprasystemic in 18 patients (69.2%),systemic in 6 (23.1%),less than systemic pressures in 2 (7.7%);the others were pa/IVS with ASD(6 patients),PFO(25),PDA (25).Palliative and definitive operations were performed on 22 patients.The results show that de-termining the morphology of RV and the hemodynamics before operation is helpful in selecting appropriate operation for lowering the operative mor-tality. ......
