role of speckle tracking in precise localization of accessory pathway in Wolff-Parkinson-White syndrome

Background: The non-Doppler echocardiographic technique known as two-dimensional speckle tracking echocardiography (2D-STE) has been demonstrated to help assess dyssynchrony and allow quantification of cardiac deformity timing in 2D greyscale images. This study evaluated the role accessory pathway (AP) localization compared electrophysiology (EPS) gold standard technique. Methods: was performed on patients with evident Wolff-Parkinson-White (WPW) syndrome who were recommended undergo EPS ablation. Patients recruited based results from resting ECG, clinical history recurrent palpitations, or an ECG confirmed bouts atrioventricular reentrant tachycardia (AVRT). using electrocardiography, conventional echocardiography, 2D-STE assessed for possibility Results: Thirteen included (seven males six females) a mean age 29.23 ± 9.3 years. All had negative family WPW syndrome. revealed that AP posteroseptal 4 (30.8%), anteroseptal 3 (23.1%), right lateral 2 (15.4%), left 1 (7.7%), anterolateral posterior (7.7%).
