All collected patients still repetitively suffered from hemodynamic disturbance induced by rapid anterograde conduction of AF via pathway, even guideline recommended acute interventions of intravenous antiarrhythmic therapy and cardioversion had been performed. Finally, as an emergency procedure, catheter ablation of accessory pathway was performed in collected patients. Correspondingly, the hemodynamic unstable status was greatly relieved. Meanwhile, all collected patients with high risk of pre\u2010excited AF were combined with left\u2010sided accessory pathway, with shortest RR interval of widened pre\u2010excited QRS complex less than 250 ms. Thus, combination with left\u2010sided pathway is proposed as an indicator for the increased risk of life\u2010threatening events in patients with high risk of pre\u2010excited AF.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Emergency catheter ablation of accessory pathway is an effective option for the acute managements of patients with high
