Embolisation of perimembranous ventricular septal defect occluder and transcatheter retrieval
The incidence of device embolisation in our centre was 0.82% (seven embolisations in 852 device placements). The main causes for device embolisation included undersized devices and inadequate subaortic rims. Among the seven embolisations, six of the devices were retrieved percutaneously without mortality, while one was retrieved during surgery. Of these patients, five had a HeartR(TM) Membranous VSD occluder of their PMVSDs, and the remaining two had surgical PMVSD closures.
