“…Device embolisation is the most common complication (prevalence 0.55-0.62%), often requiring surgical retrieval (Levi and Moore, 2004;Moore et al, 2013). Another rare, but potentially fatal complication is erosion or cardiac perforation (reported only with certain device types), estimated to occur in 0.1% to 0.28% of all cases and reported as late as eight years after deployment (Amin et al, 2004;DiBardino et al, 2009;Moore et al, 2013;Roberts et al, 2013). More rarely, device infection with subsequent endocarditis, nickel allergy, thrombus formation or residual/recurrent defect following device closure can occur (DiBardino et al, 2009;Moore et al, 2013).…”
