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 < 0.001), whereas no significant difference in the distance between right superior PV (RSPV) and right main bronchus (RMB) was found between groups (11.9 ± 3.5 mm vs. 12.9 ± 4.6 mm, P = 0.089). Additionally, the mean thickness of the connective tissue interposed between RSPV and RMB was significantly thicker than that between LSPV and LMB in both groups (both P < 0.001). A stepwise logistic multivariate analysis identified only the LMB‐LSPV distance as an independent predictor of hemoptysis (odd ratio [OR] 2.676; 95% CI 1.121–4.843, P < 0.001). A cutoff value ≤ 9.5 mm predicted hemoptysis after CB ablation with 93.8% sensitivity and 75.0% specificity. Conclusion Hemoptysis is a relatively rare event following second‐generation CB ablation. The bronchi location obtained from CT aids in identifying high‐risk population for the complication.
