Predictors of hemoptysis in the setting of pulmonary vein isolation using the second‐generation cryoballoon

Introduction To assess the predictors of hemoptysis using second‐generation cryoballoon (CB). Methods Thirty patients with hemoptysis after second‐generation CB ablation and 60 age‐, gender‐, and body mass index‐matched controls were recruited. Anatomic parameters were obtained from preprocedural cardiac computed tomography (CT). Pulmonary vein isolation was performed with 28‐mm balloon using single 3‐minute freeze technique. Results Clinical and procedural characteristics were similar between the groups. A shorter distance between left superior PV (LSPV) and left main bronchus (LMB) was associated with hemoptysis (7.8 ± 4.3 mm vs. 12.5 ± 3.5 mm, P
