This report summarizes the efficacy, safety, and feasibility of intracardiac ultrasound(ICUS) and local electrographic-guided pulmonary vein(PV)-left atrial disconnection, including the isolation of common PV trunks accomplished in 170 consecutive patients with atrial fibrillation(AF). A left common PV was found in 43%of patients with AF. During a follow-up of 549±330 days after ablation, the AF-free survival rate was 80%and comparable in paroxysmal and persistent AF. PV stenosis was detected in only 1 asymptomatic patient, who required no intervention.
