Comparison of VSD closure with single patch and flap valve patch in VSD patients with systemic pulmonary hypertensin at Rajaie Heart center

Back ground:Back ground: closure of large ventricular septal defect (VSD) in children with elevalled pulmonary vascular resistance (PVR) is associated with significant morbidity and mortality. Surgical cure is likely to result in any infant in whom the VSD is repair before age 6 to 9 months, irrespective of degree of pulmonary vascular resistance .Methods:sixty-five patients (mean age of 21.20±52.08 month) with large size VSD and pulmonary hypertension Underwent VSD closure. That Double flap valve patch technique were used in 14 patients (21.7%).Results:After operation there was one Residual VSD needs Reoperation. Early mortality was 4.5% and RBBB and CHB were seen in 1.5% of patients.Echocardiography 6months ofter operation showed that all double patches were closed.Conclusion:Double flap valve patch technique is a safe operation and can be used for closure of large VSD with the systemic pulmonary hypertension and morbidity of this technique is the same as single patch. It has a safety guard in early post operative period and we have to compare this two techniques in a double blind Experiment in the future.
