ABSTRACT
<p><b>OBJECTIVE</b>To study the relationship between the age at operation and prognosis in children with severe pulmonary hypertension (PH) due to ventricular septal defect (VSD).</p><p><b>METHODS</b>Forty children with severe PH (increased total pulmonary circulation resistance)due to VSD were divided into two groups based on age at operation(Group I aged less than 2 years and group II more than 2 years). The hemodynamic parameter follow-up was measured by cardiac catheterization at presurgery, one week after surgery and 5-7 years postoperatively.</p><p><b>RESULTS</b>The ratio of pulmonary arterial pressure and systemic arterial pressure (pp/ps),pulmonary resistance and systemic resistance (R(p)/R(s)), and pulmonary vascular resistance (PVR) and small pulmonary arterial resistance (PAR) were significantly different in two groups (P<0.01). During follow-up in the group less than 2 years, all the hemodynamic parameters were at normal level, while in the group more than 2 years, only p(p)/p(s) and R(p)/R(s) were close to normal level. The pulmonary arterial resistance was still abnormal.</p><p><b>CONCLUSION</b>An early operation may be the only way to gain optimal long term result of surgery and decrease the incidence of pulmonary vascular disease in children with PH due to VSD.</p>
