The Incidence of Phrenic Nerve Injury During Pulmonary Vein Isolation Using the Second‐Generation 28 mm Cryoballoon

Abstract

Using the second-generation 28 mm CB, PNP occurred in 4 of 115 (3.5%) patients. While 1 of 4 PNP recovered 10 months after ablation, long-term outcome in the remaining 3 patients is currently unknown due to the rather short follow-up period.
