Rapid ventricular pacing to optimize rotational angiography in atrial fibrillation ablation

Background Conventional pulmonary vein (PV) angiography cannot precisely delineate the left atrium (LA)–PV anatomy, which is essential for the ablation of atrial fibrillation (AF). The aim of the study was to test the feasibility of a novel method of rotational angiography for the AF ablation.
