First catheter-based high-density endocardial 3D electroanatomical mapping of the right atrium in standing horses.

ABSTRACT:

Background

Three-dimensional electroanatomical mapping is of potential interest in equine cardiology to identify arrhythmia mechanisms, characterise electroanatomical substrates and guide ablation strategies.

Objectives

To describe three-dimensional electroanatomical mapping in standing horses.

Study design

Research methodology, proof of concept study.

Methods

Four Standardbred horses (2 geldings, 2 mares, median age 4.5 [4-9] years, mean bodyweight 485 [440-550] kg) were sedated and placed in stocks. Via the jugular vein, a high-density multipolar grid catheter (Advisor^™ HD Grid Mapping Catheter with EnSite VelocityTM, Abbott Medical) was used for endocardial mapping of the right atrium. The P-wave on the surface ECG was used as a timing reference f
