Immediate Results of Pulmonary Veins Entries Cryoblation of Patients with Atrial Fibrillation // Direkte Ergebnisse der Kryo-Ablation der PV-Ostien bei Patienten mit Vorhofflimmern Zeitschrift für Gefäßmedizin 2018; 15 (3): 11-16 Volltext (PDF) Summary Abbildungen
Keywords: Katheterbehandlung, Kryo-Ablation, PV-Ostien, Vorhofflimmern, atrial fibrillation, catheter treatment, cryoablation, isolation of pulmonary veins entries Background: The aim of this study is to estimate pulmonary veins ostia cryoablation method and patient treatment results with atrial fibrillation (AF) using cryotechnologies. The study’s design is a cross-section analysis of prospective study conducted in the interventional cardiology, arrhythmology, and endovascular surgery department of JSC National Scientific Center of Surgery. Material and Methods: Collected data from October 2014 to April 2017. There were 240 patients with tachysystolic AF resistance to antiarrhythmic therapy. Had been conducted invasive electrophysiological study and 240 cryo­ablation interventions. In this study, the average number of cryoactivities in one PV was 1.5 ± 0.5, and the total average number of cryoapplications was 6 ± 2 per patient. Total duration of cryoablation reached 24.8 ± 12.6 min. Every three months, a Holter ECG was conducted to evaluate freedom from arrhythmias and to extraordinary ECG when suspicious arrhythmia symptoms appeared upon Holter monitor. Weekly telephone surveys with detailed clinical symptoms of patients were conducted. Results: Paroxysmal AF was diagnosed in 155 patients; persistent AF was diagnosed in 85 patients. Repeat left atrium catheter ablation through left atrium linear radiofrequency ablation was performed in the case of clinical manifestations of recurrent AF refractory to antiarrhythmic therapy. Conclusion: The use of technology makes it possible to achieve 96% left atrium acute electrical isolation.
Kurzfassung: Hintergrund: Zweck dieser Studie
