Abstract OBJECTIVE: To identify the risk factors for accelerated junctional escape rhythm (AJER) in children early after percutaneous ventricular septal defect (VSD) closure. METHODS: A retrospective controlled study was conducted on 42 children who had AJER within one week after percutaneous VSD closure between January 2008 and October 2012. These subjects were compared with controls without AJER after VSD closure in terms of age, sex, diameter of VSD, occluder size, difference between occluder size and diameter of VSD, and distance between VSD and aortic valve ring. Risk factors for AJER were identified by logistic regression analysis. RESULTS: Compared with the control group, the AJER group had a longer distance betweenVSD and aortic valve ring, a larger diameter of VSD (basal diameter), a larger occluder size (waist diameter) , and a bigger difference between the waist diameter of occluder and diameter of VSD (P<0.05). Logistic regression analysis showed that distance between VSD and aortic valve ring (OR=1.813, P<0.05) and occluder size (OR=1.671, P<0.05) are primary risk factors for AJER. CONCLUSIONS: AJER early after percutaneous VSD closure is related to diameter of VSD, occluder size, difference between the waist diameter of occluder and diameter of VSD, and distance between VSD and aortic valve ring. The distance between VSD and aortic valve ring and occluder size are primary risk factors for AJER.
