Comparative analysis of the treatment of partial anomalous pulmonary vein connection by double-patch method or Warden Technique / 中华胸心血管外科杂志

ABSTRACT

Objective:To compare the surgical and long-term follow-up results of partial anomalous pulmonary vein connection treated by double-patch method or Warden Technique.Methods:There were 33 cases of right pulmonary vein connected with the superior vena cava from May 2010 to May 2019 in our center treated by double-patch method or Warden technique. 21 cases were treated by double-patch method and 12 cases by Warden technique. Echocardiography and electrocardiogram were followed up regularly to observe the occurrence of arrhythmia, superior vena cava stenosis and pulmonary vein stenosis postoperatively.Results:All patients were discharged uneventfully, and were followed up for 1~8 years. In double-patch group, 2 cases with arrhythmia, 1 of whom was junctional arrhythmia which was automatically converted to sinus rhythm 1 day after surgery. The other had an early second degree atrioventricular block after surgery, and sinus rhythm was restored 3 days later with temporary pacemaker. 1 case had superior vena cava stenosis by echocardiography(PD 8 mmHg). No arrhythmia was found in long-term follow-up in Warden group. 2 cases had superior vena cava stenosis by echocardiography(PD 6 mmHg). Right pulmonary vein stenosis(PD 8 mmHg) was found in 1 case by echocardiography, no obvious aggravation was found in long-term follow-up.Conclusion:The double-patch method and Warden Technique are both safe and effective in the treatment of partial anomalous pulmonary venous connection.
