Dear jd,
Lead perforation is not that common but it is a potential complication of pacemaker placement. The atria are very thin walled structures, especially in an 86 year old. Pacemaker leads are stiff and it is possible for them to go through the wall of the heart. The incidence of lead perforation is less than 2% and of those the need to go to surgery is probably less than half. It's hard to say exactly when the perforation occured but it was probably when she experienced the chest pain.
Does anyone know whether this is an acceptable or unacceptable risk of the procedure for a right-handed person . The surgeon reported that his patients were more comfortable with the procedure on the non-dominant side and he knows about the removal of the nodes.
Thank you for your help and information.
