ABSTRACT
Objective:
Our purpose was to evaluate a new kind of tomographic phase analysis in Wolff-Parkinson-White (WPW) syndrome .Methods:
Planar and new tomographic gated blood pool scintigraphy were performed in 66 patients with WPW syndrome and 55 healthy subjects , in which 30 patients were examined again after radiofrequency ablation . The abnormal initial contractions in both planar and tomographic phase image were compared with the sites of accessory pathway (ACP) based on ECG and radiofrequency ablation .Results:
The phase angle shift in WPW group was significantly different from that in healthy subjects .New tomographic phase analysis can detect the sites of ACP more precisely than planar phase analysis and ECG ( 93.9%, 80.3%, 79.0%, respectively ).The average phase angle shift in WPW group after operation was less than that before operation (P< 0.01 ) .Tomographic phase analysis discovered two mutiple ACPs and latent ACP that can not be found by ECG.Conclusion:
The new tomographic phase analysis is a promising method to detect the sites of ACP and can be used to evaluate the efficacy of operation.
