Transient ST-segment elevation during transseptal catheterization for atrial fibrillation ablation.

For the treatment of refractory left atrial tachyarrhythmias, including atrial fibrillation, transseptal catheterization is often performed in order to achieve pulmonary vein isolation and left atrial substrate ablation. Herein, we report an unexpected ST-segment elevation in a 71-year-old man during a Brockenbrough transseptal catheterization procedure for… CONTINUE READING
