1 Hemoptysis after five months of cryoballoon ablation: What is the relationship? 
Keita Watanabe, MD, Junichi Nitta, MD, PhD, Akira Sato, MD, Masahiko Goya, MD, PhD, Mitsuaki Isobe, MD, PhD, Kenzo Hirao, MD, PhD, FHRS  HeartRhythm Case Reports  Volume 3, Issue 7, Pages (July 2017) DOI: /j.hrcr Copyright © 2017 Heart Rhythm Society Terms and Conditions

2 Figure 1 A, B: The deep position and incomplete circle of the balloon in the left superior pulmonary vein can be seen in angiography. C: Considerable blood volume in the left lower trachea and coagulation and blood outflow with coughing was observed on bronchofibroscopy at segment 4–5 of the left lung.

3 Figure 2 Temperature trend of the left superior pulmonary vein. At 30 seconds, the temperature was −40°C. The balloon temperature reached −60°C at 80 seconds. The nadir temperature was −65°C.

4 Figure 3 No pulmonary vein stenosis was observed on contrast-enhanced computed tomography (A, B; preablation). Five-and-a-half months after ablation, severe stenosis of the left superior pulmonary vein and complete occlusion of the pulmonary vein for the lingular segment were observed (C, D).
