Abstract

Objective: Wolff-Parkinson-White Syndrome (WPW) is a clinical entity that is diagnosed with typical surface electrocardiogram hallmarks and intermittent tachycardia episodes. Patients may present with sudden cardiac death due to wide QRS tachycardia or stay asymptomatic for life and may be diagnosed incidentally. Pharmacological treatment options are limited in this patient group. Cornerstone of therapy is ablation of the accessory pathway as it is recommended by guidelines. In this sturdy, we aimed to evaluate single centre data of WPW patients, including procedural and follow up data, who had undergone ablation.
Materials and Methods: Health Sciences University Samsun Training and Research Hospital electronic data between December 2015 and December 2018 were analysed. Data of patients who underwent ablation therapy were collected. Procedural data, baseline characteristics and follow up data were acquired.
Results: For all procedures, acute procedural success rate was 97%, long term success rate was 94%. Mean procedure time was 117,12±1,8 minutes, mean ablation time was 6,28±0,4 minutes. Median follow-up duration was 16,5 (6-38) months. Complication rates were: 3 (3,2%) groin/puncture site complications, 3 (3,2%) pericardial effusions, 1 (1%) stroke, 1 (1%) block requiring pacemaker, 1 (1%) spontaneously recovered cardiac perforation.
Conclusion: Our results demonstrated that single centre rates for success were like expected rates and recurrences/complications were lower than expected rate in literature. Findings suggest that flawed choice of equipment and technique contributes to prolonged procedure durations and failure of acute success and increased rate for recurrences. We think that operator experience, dedicated electrophysiology personnel and laboratory along with utilization of complex electroanatomic mapping systems are vital for more successful outcomes in complex procedures.
