Does direct coronary sinus angiography identify venous anomalies that facilitate successful ablation in patients with left posteroseptal accessory pathways?
Direct coronary sinus angiography reveals venous anomalies in a majority of patients with left posteroseptal accessory pathways, facilitating successful targeted ablation from within the venous branches.
