“…In this study, we only investigated the radial myocardial acceleration acquired from parasternal short‐axis views. This was because the detections of the accessory atrioventricular pathways in WPW syndrome or the position of onset of ventricular acceleration during sinus rhythm in previous studies were mainly from short‐axis views 5–11 …”

“…Preexcitation is known to alter ventricular activation sequence and result in focal areas with presystolic contraction 1 . It has been reported that two‐dimensional, M‐mode, and tissue Doppler imaging (TDI) echocardiography can be used to detect the site of initial contraction of the ventricle and then to localize the ventricular emergence site of accessory atrioventricular pathways in patients with Wolff‐Parkinson‐White (WPW) syndrome 2–6 . Myocardial acceleration is proportional to the change of velocity over time and is more sensitive to the rapid change of tissue motion than velocity.…”

The time point of onset of myocardial active contraction during early systole cannot be determined in most of normal myocardial segments. Also, there is homogeneity of the time to early systolic peak acceleration in the whole normal LV walls. Myocardial acceleration seems to have limited potential in the assessments of the site of initial electrical stimulation and the sequence of ventricular depolarization.

“…The higher accuracy of TD versus M-mode imaging was shown in some reports where the early excitation sites were missed by M-mode imaging in nearly half of the patients, but were readily identified in most by TD (Fig. 3) [36]. Furthermore, TD was superior in identifying rightsided accessory pathways.…”

Endocardial mapping and radiofrequency catheter ablation are well established modalities for the diagnosis and treatment of patients with Wolff-Parkinson-White (WPW) syndrome associated with tachyarrhythmias. However, the electrophysiologic techniques are invasive, require radiation exposure, and lack spatial resolution of cardiac structures. A variety of echocardiographic techniques have been investigated as a non-invasive alternative for accessory pathway localization. Conventional M-mode echocardiography can detect the fine premature wall motion abnormalities associated with WPW syndrome. However, it is unable to identify the exact site of accessory pathway with sufficient accuracy. 2D, 2D-guided M-mode, and 2D phase analysis techniques are limited by image quality and endocardial border definition. Various modalities of tissue Doppler echocardiography significantly increase the accuracy of left-sided accessory pathway localization to 80-90% even in patients with poor acoustic window. However, right-sided pathways remain a diagnostic challenge. Strain echocardiography by speckle tracking has recently been evaluated and appears promising. Different cardiac abnormalities have been detected by echocardiography in WPW patients. Patients with WPW syndrome and tachyarrhythmias have impaired systolic and diastolic function which improves after radiofrequency ablation. Echocardiography is useful in identifying patient with accessory pathway-associated left ventricular dyssynchrony and dysfunction who may benefit from ablation therapy. Transesophageal and intracardiac echocardiography have been used to guide ablation procedure. Ablation-related complications detected by routine echocardiography are infrequent, rarely clinically relevant, and of limited value.
