Optimal site of pacemaker lead implantation for persistent atrial standstill guided by electroanatomical mapping following a cox-maze procedure: a case report.

ABSTRACT:

Background

Atrial standstill is characterized by the absence of atrial activity. We report a case of a patient with extensive atrial fibrosis who underwent electrophysiologic study (EPS) and electroanatomical mapping (EAM) to identify surviving atrial sites amenable for pacemaker lead implantation.

Case summary

A 72-year-old man with persistent atrial fibrillation (AF) and atrial functional mitral regurgitation/tricuspid regurgitation (MR/TR) underwent a Cox-Maze surgery, mitral and tricuspid valve repair, and biatrial plication. He was referred because of post-operative presyncope symptoms. Electrocardiography revealed atrial standstill and junctional rhythm (JR); however, EAM revealed that both atria were almost entirely scarred and isolated fibrillation in left pulmonary
