Radiofrequency catheter ablation within the pulmonary artery successfully eliminated symptomatic premature ventricular contractions that could not be abolished by ablation in the right ventricular outflow tract.
Case Report (n=1)
No
A patient underwent radiofrequency (RF) catheter ablation of symptomatic idiopathic ventricular contractions (PVCs). RF energy applications at 2 sites in the right ventricular outflow tract (RVOT), where both the earliest ventricular activation and near-perfect pace mapping were obtained, did not abolish the PVC but resulted in changes in the QRS morphology of the PVC. Complete elimination of the PVC was achieved with RF energy application at a site within the pulmonary artery 13 mm above the pulmonary valve, which was greater than 20 mm away from the failed ablation sites within the RVOT.
Tada et al. (Sat,) conducted a case report in Symptomatic idiopathic premature ventricular contractions (n=1). Radiofrequency catheter ablation in the pulmonary artery vs. Radiofrequency catheter ablation in the right ventricular outflow tract was evaluated on Complete elimination of premature ventricular contractions. Radiofrequency catheter ablation within the pulmonary artery successfully eliminated symptomatic premature ventricular contractions that could not be abolished by ablation in the right ventricular outflow tract.
