This complaint is from a literature source: a conference abstract of ¿catheter ablation sapporo 2017¿ in japanese.It was reported that one (b)(6) male patient with paroxysmal atrial fibrillation underwent radiofrequency ablation procedure using smarttouch ablation catheter on (b)(6) 2016.Patient had heavily symptomatic atrial fibrillation attacks frequently since (b)(6) 2016.Due to asa and the volume of the left atrium were small, it was difficult to have septal puncture.A right atrium contrast was added and it was successfully punctured with the catheter inserted into the left atrium.During bilateral pulmonary venous isolation, blood pressure dropped, infusion solution and noradrenaline administration were required.No observation of cardiac tamponade but anemia and fluid retention in the right thoracic cavity were confirmed.Right thoracic drainage and emergency right thoracotomy to provide hemostatic status were performed.Procedure was completed.It was inferred that the bleeding point was between the parietal wall and the left atrium and hemorrhage was done by suturing.Patient was recovered and discharged after six months' hospitalization.The physician commented that it was a small left atrial volume in cases of pulmonary disease complicated atrial fibrillation.As with asa, it was suspected the event was due to the septal puncture needle (japan lifeline) through the left atrioventral wall into the right thoracic cavity.The cause of the compilation was that the procedure was continued without confirmation by eco.
