A case of WPW Syndrome due to parahisian accessory pathway was ablated by the catheter inversion technique. The pathway could not be eliminated by direct femoral approach using repeated high radiofrequeny energy ablation. No pathway potential was seen in the aortic cusps. Instead, it was successfully ablated by curving the ablation catheter underneath the septal leaflet of the tricuspid valve t...

Catheter ablation of Wolff-Parkinson-White syndrome is associated with up to 5% of failure. Coronary sinus (CS) abnormalities or connections between CS myocardial coat and left ventricular epicardium are associated with posteroseptal and left posterior accessory pathways (AP). A 41-year-old patient with WPW syndrome was referred to our hospital after three unsuccessful ablations. The 12-lead EC...

ECG in sinus rhythm with ventricular preexcitation and changing QRS morphology was seen that was initially interpreted as the multiple accessory pathway from elsewhere. (Figure 1A). The following mechanisms are potentially involved in the electrogenesis of changing QRS morphology in WPW syndrome: 1) multiple accessory pathways1; 2) simultaneous occurrence of aberrant atrioventricular conduction...

Noncompaction cardiomyopathy (NCCM) is a rare primary cardiomyopathy caused by an arrest in myocardial morphogenesis. The clinical manifestations are highly variable from asymptomatic to severe heart failure, arrhythmias, sudden cardiac death, or systemic thrombo-embolic events. Association of NCCM and electric disorders has been reported as rare case reports with WPW syndrome and Brugada syndr...

We reported two patients who presented with non-specific chest symptoms with ECG changes mimicking acute myocardial infarction and ventricular hypertrophy. Both of them were finally confirmed to have Wolff-Parkinson-White (WPW) syndrome after spontaneous resolution of the ECG changes. As a matter of fact, other differential diagnosis should be considered with respect to the ST-segment changes. ...

OBJECTIVE To determine the level of knowledge concerning Sudden Unexpected Death in the Young (SUDY) among Canadian medical students and recent graduates (≤5 years after graduating). DESIGN A cross-sectional study was conducted by distributing a standardised, multiple choice, online questionnaire which assessed basic knowledge of SUDY. SETTING Canadian medical schools and residency training...

Patients with a Wolff-Parkinson-White (WPW) pattern in the electrocardiogram (ECG) show a short PR interval (<120 ms), a wide QRS complex (>100 ms) with a delta wave, and a normal PJ interval. Broad QRS complexes may simulate bundle branch block (BBB). Furthermore, premature depolarization of ventricular myocardium through an accessory pathway tends to conceal any electrocardiographic manifesta...
