Objective: To evaluate the post-operative complication of pulmonary vein stenosis in patients with total anomalous pulmonary venous connection (TAPVC) by echocardiography.
Methods: A total of 66 TAPVC pediatric patients with surgical repair in our hospital were retrospectively studied. The peri-operative and mid-term post-operative echocardiography was conducted to evaluate the complication of pulmonary vein stenosis.
Results: The peri-operative and mid-term post-operative echocardiography presented the increased left ventricular diastolic end diameter (LVEDd) and decreased right ventricular diameter in all 66 patients, P<0.05. There were 6 patients with pulmonary vein stenosis showed high velocity Doppler signals at atanastomosis. The peri-operative echocardiography in those 6 patients showed increased LVEDd, decreased right ventricular diameter and pulmonary artery pressure, all P<0.05. The mid-term post-operative echocardiography in those 6 patients indicated increased LVEDd, P<0.05, while the right ventricular diameter and pulmonary artery pressure were similar before and after the operation, P>0.05.
Conclusion: Echocardiography may monitor the operative effect of TAPVC, the occurrence of post-operative pulmonary vein stenosis could be found by examining right ventricular diameter and pulmonary artery pressure in pediatric patients.
