Background Wolff‐Parkinson‐White (WPW) syndrome is one of the most common congenital cardiac abnormalities among ventricular pre‐excitation syndromes. Radiofrequency catheter ablation (RFCA) treatment of accessory pathways (APs) in WPW patients is an established curative therapy restoring normal atrioventricular conduction. We have not encountered any studies evaluating both the LA and LV functions of these patients before and after RFCA with three dimensional‐speckle tracking echocardiography (3D‐speckle tracking echocardiography (STE)). Aim The purpose of the current study was to assess the LA and LV functions in patients with WPW syndrome before and after RFCA using 3D‐STE. Methods A total of 21 patients with WPW syndrome who had been scheduled for RFCA were prospectively recruited for this study. 3D‐STE examinations of the patients were performed 12–24 h before ablation and 1 month after ablation. Results The LV‐global longitudinal strain (LV‐GLS) and LV‐global circumferential strain (LV‐GCS) were significantly depressed in the pre‐RFCA WPW group than in the control group (−14.3 ± 2.1 vs. −21.5 ± 2.2, p < .001; −12.6 ± 1.8 vs. −20.4 ± 1.8, p < .001, respectively). The left atrial strain‐reservoir (LAS‐r) and LAS‐active were significantly decreased in the pre‐RFCA WPW group than in the control group (31.9 ± 2.4 vs. 48.8 ± 2.6, p < .001; 11.7 ± 2 vs. 26.5 ± 2.1, p < .001, respectively). The LV‐GLS, LV‐GCS, LAS‐r, and LAS‐active values improved after RFCA compared to before. Conclusion The results of our study indicated that there are subclinical impairments in LV and LA myocardial dynamics in the apparently healthy WPW patients, and these deteriorations improve after RFCA of AP.

“…In another study, Karakoyun et al. aimed to test the LA mechanics and contraction synchrony by 2D strain imaging, in patients with WPW syndrome, before and after RFCA 35 . They showed that LA mechanical function assessed by 2D strain imaging was comparable between patients with WPW and control subjects.…”
