Pulmonary air embolism is a potentially lethal complication of catheter
ablation of cardiac arrythmias.We present a 50 year old man with
pulmonary embolism during cryoballoon ablation of atrial fibrillation.
Deep breath of patient while inserting the sheath into left atrium from
right femoral vein was main cause of pulmoary air embolism. Air bubble
was dispersed by hitting on it with the pigtail catheter and pulmonary
flow was achieved. The patient was discharged without any sequelae.
