Inadvertent lead malposition in the left heart is a rare (0.34%) but serious complication of device implantation that can cause cerebral embolism, and is associated with scoliosis, congenital heart disease, and limited operator experience.
Ohlow et al. (2015) conducted a cohort in Heart rhythm device implantation (n=2,579). Inadvertent lead malposition vs. No inadvertent lead malposition was evaluated on Incidence of inadvertent lead malposition. Inadvertent lead malposition occurred in 0.34% of patients undergoing heart rhythm device implantation, with scoliosis, congenital heart disease, and limited operator experience as key risk factors.
