Aims:
In this study, we aim to summarise our experience with techniques used for the transcatheter retrieval of embolised devices.
Methods:
We retrospectively reviewed the transcatheter retrieval of embolised devices in seven patients who underwent an attempted transcatheter closure of perimembranous ventricular septal defects (PMVSDs) between October 2002 and October 2013. The incidence, the main causes for the device's embolisation, and the techniques for transcatheter retrieval of the embolised device are discussed.
Results:
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.
Conclusions:
Our approach to the transcatheter retrieval of the embolised devices is associated with good results.
