Isthmic radiofrequency catheter ablation of typical atrial flutter was complicated by complete atrioventricular block due to acute right coronary artery occlusion, which resolved upon recanalization.
Case Report (n=1)
We report the case of a 51-year-old patient who developed a complete atrioventricular (AV) block during the isthmic radiofrequency catheter ablation of a typical atrial flutter. The cause was an acute occlusion of the segment three of the right coronary artery. His recanalization was associated with the immediate restoration of a normal AV conduction. The complication is exceptional (one of 740 consecutive atrial flutter ablations). (PACE 2010; 516-519).
Brembilla-Perrot et al. (Fri,) conducted a case report in Atrial flutter (n=1). Isthmic radiofrequency catheter ablation was evaluated on Complete atrioventricular block. Isthmic radiofrequency catheter ablation of typical atrial flutter was complicated by complete atrioventricular block due to acute right coronary artery occlusion, which resolved upon recanalization.
