PO-708-04 HIGH DENSITY ELECTROANATOMICAL MAPPING FOR TARGETED PACING LEAD PLACEMENT IN PATIENTS WITH ATRIAL MYOPATHY

Atrial myopathy can occur secondary to surgical scaring and fibrosis, particularly in patients with congenital heart disease (CHD). Atrial lead placement in these patients can be challenging as intra/inter-atrial conduction may be segmented and with variable atrioventricular (AV) conduction. The feasibility of electroanatomical mapping to facilitate pacing lead placement has been under reported.
