A 36 year-old man with Wolff Parkinson White syndrome due to a left-sided accessory pathway (AP) was referred for catheter ablation. Whether abolition of antegrade and retrograde AP conduction during ablation therapy occurs simultaneously, is unclear. At the ablation procedure, radiofrequency delivery resulted in loss of preexcitation followed by a short run of orthodromic tachycardia with ecce...

In 1930, Dr Louis Wolff, Sir John Parkinson, and Paul Dudley White described a case series of 11 patients with a syndrome that now bears their name.1 The first patient with a short PR interval, ventricular preexcitation, and supraventricular tachycardia was described by Cohn and Fraser in 1913.1 Wood et al postulated the accessory pathway (AP) as its anatomic substrate in 1942, and a large popu...

OBJECTIVE To report retrospectively on the training and subsequent experience of two operators in transseptal ablation of arrhythmias arising in the left atrium and left atrioventricular annulus, to show whether, with adequate training and careful attention to detail, this is a safe and effective technique. SETTING Electrophysiological studies and transseptal procedures were performed in the ...

Among patients with a Wolff–Parkinson–White (WPW) syndrome, approximately half will experience arrhythmia during their lifetime. Radiofrequency catheter ablation of the accessory atrioventricular pathway is the treatment of choice for this condition and is associated with a high success rate. Electrophysiology study is indeed the key procedure for identifying the target of radiofrequency ablati...

OBJECTIVES This study was designed to prospectively evaluate the effects of radiofrequency ablation in Wolff-Parkinson-White (WPW) syndrome by scintigraphic analysis. BACKGROUND The functional changes triggered by radiofrequency current ablation of atrioventricular accessory pathways are not fully known. METHODS Forty-four patients with WPW syndrome were consecutively investigated before an...

The most common types of supraventricular tachycardia are caused by a reentry phenomenon producing accelerated heart rates. Symptoms may include palpitations (pulsation in the neck), chest pain, lightheadedness or dizziness, and dyspnea. It is unusual for supraventricular tachycardia to be caused by structurally abnormal hearts. Diagnosis is often delayed because of the misdiagnosis of anxiety ...

The combination of rheumatic mitral stenosis and Wolff-Parkinson-White syndrome is a rare situation. In this case, we are reporting an 72-year-old man presenting with multi-organ failure due to the this combination and successfully treated with radiofrequency ablation during preexcitated atrial fibrillation.
