OBJECTIVE: We have designed a study, whose aim was to confirm the feasibility and safety of the zero fluoroscopy approach in the treatment of supraventricular tachycardias (SVT) and premature ventricular contractions (PVCs) originating in the right ventricle in a secondary centre located in the south of Belgium.
METHODS: We included in our retrospective analysis patients with a clinical history and/or electrocardiographic documentation of SVT or frequent symptomatic monomorphic PVCs referred to our centre from November 2019 to March 2020 for catheter ablation.
RESULTS: A total of 49 patients were considered eligible for potential enrolment in the study, 3 were excluded because of presence of a manifest left sided atrio-ventricular accessory pathway, 5 because of left ventricular PVCs and 4 because of left atrial tachycardia. 4 patients were instead excluded because of need of utilisation of fluoroscopy during the procedure. A total of 33 patients were therefore included in the analysis. Right atrial flutters and typical AVNRT were the most common arrhythmia treated, corresponding together to the 81% of the total. Right femoral access was obtained in 86% of cases with left femoral access used in the remaining when right femoral access was not successful after the third attempt. Coronary sinus cannulation was efficacious within 10 min in 76% of cases. There were four minor complications overall.
CONCLUSION: The main finding of our study is that non-complex ablations can be performed on zero-fluoroscopy safely and with a good clinical outcome also in a secondary centre.
