    Abstract
  •   Objective  To evaluate the safety and efficacy of cryoballoon catheter ablation (CCA) in patients with atrial fibrillation Combining with heart failure.  Methods  A retrospective analysis of 3 patients with atrial fibrillation Combining with heart failure diagnosed at the First Affiliated Hospital of the University of Science and Technology of China from June 2020 to November 2020 was performed to observe the safety of CCA treatment. The results of echocardiography, dynamic electrocardiogram, cardiac function grading and N-terminal B-type natriuretic peptide (NT-proBNP) were examined after 3 and 6 months to observe the effectiveness of CCA therapy.  Results  All patients successfully achieved complete pulmonary vein isolation (PVI). Patient 1 converted to atrial flutter after PVI, which was proven to be typical atrial flutter and dependent on tricuspid isthmus by activation and entrainment mapping, and then turned to sinus rhythm after tricuspid isthmus isolation. Electrocardioversion of patients 2 and 3 turned to sinus rhythm following pulmonary vein isolation, and atrial voltage was mapped under sinus rhythm. All three patients had neither matrix modification nor complications. Echocardiography significantly improved (LVEF increased by 28%, 32% and 21% at 6 months post-operation, respectively; LVEDD and LAD significantly reduced), and NYHA functional class all improved to Ⅰ. The BNP of all patients reduced to the normal range. However, recurrence was found in patient 1 at 6 months follow-up. The successful CCA treatment was administered again, and no AF occurred at 6 months follow-up.  Conclusion  CCA for patients with atrial fibrillation Combining with heart failure is safe, which may improve cardiac function and cardiac structure and reduce NT-proBNP.
