Implantation of submammary implantable cardioverter defibrillators

Implantable cardioverter defibrillators (ICDs) are routinely placed in the left pectoral area using a transvenous approach. This approach may result in poor cosmetic outcome and cause psychological problems, especially in younger patients. To avoid this, several alternative implantation techniques have been developed. For cosmetic reasons, we used a submammary technique to implant ICDs into three young women. Apart from defibrillation threshold testing, the procedures were performed under local anesthesia. Threshold testing was done under general anesthesia. Appropriate defibrillation thresholds were obtained in all three cases, and all the patients tolerated the procedure well. There were no complications in a mean of 22 months of follow-up, and the cosmetic results were very good.
