Abstract:
Objective To investigate the characteristics of the newly discovered tricuspid injury during the fol-low -up of the patients with interventional transcatheter closure for perimembranous ventricular septal defect (VSD). Methods A retrospective analysis of clinical data was performed in the successful completion of membranous VSD in-tervention from March 2003 to April 2015,and 11 cases of serious tricuspid injury in children were found during the fol-low -up.Results Among 11 children,10 cases underwent surgery again,and in 7 cases of them with pseudoaneurysm of perimembranous septum,the occluders were deviated toward the right ventricul which caused valvular inadequacy for plate winding closures,extrusion and wear of tricuspid chordae and /or leaflet by right ventricul(RV)disc.Among them,1 case was caused by leaflet fusion tear and tricuspid valve insufficiency;3 cases without pseudoaneurysm were caused by a spindle like RV disc recovery structure protruding into the right ventricle,and then the disc squeezed the tricuspid tendinous cord or leaflet and the right ventricular disc nut wrapped tendon of tricuspid valve finally leading to tricuspid valve insufficiency.There was a small amount of tricuspid regurgitation after surgery;the cardiac size and car-diac function returned to normal.One case did not receive surgery,and at present the right atrium and right ventricle were significantly enlarged,and the activity was limited.Conclusions Tricuspid injury discovered newly after perimem-branous VSD interventional therapy is more common in pseudoaneurysm with large tumor occluding the right ventricular disc resulting in poor formation,and it is important to consider these factors in choosing the size of the occluder and the operation.Long term follow -up mechanism should be established for the treatment of VSD after interventional therapy.
