ABSTRACT
Objective To analyze retrospectively the results of single-patch with elevation of the left-sided atrioventricular valve repair for complete atrioventricular septal defect(CAVSD) in therapeutic effects and safety.Methods Fourteen consecutive patients (2 males and 12 females) with CAVSD were enrolled in the study from April 2012 to December 2017.All patients underwent single-patch with the elevation of left-sided atrioventricular valve repair for CAVSD by regular sternotomy.The median age at operation was 12.5 months(range,11.7 months to 63 months) and the duration of follow-up was(3.27 ± 2.02)years.Echocardiography and electrocardiogram were used during follow-up according to the protocol.Results Compared with pulmonary arterial pressure(PAP) during pre-and post-operation (65.92 ± 6.91 and 62.97 ± 17.29) mmHg (1 mmHg =0.133 kPa),PAP(53.29 ± 20.99) mmHg decreased significantly during follow-up period.There were significant difference during post-operation and follow-up for LAVVR and RAVVR.The extent of regurgitation of atrioventricular valve statistically decreased during follow-up period.None of patients suffered from atrioventricular block and reoperation during follow-up.Conclusion Single-patch with elevation of the left-sided atrioventricular valve repair for CAVSD yields good outcomes,without occurrence of severe LAVVR,during early and mid-term follow-up period.
