Segmental dyskinesia in Wolff–Parkinson–White syndrome: A possible cause of dilatative cardiomyopathy
2006
Wolff-Parkinson-White (WPW) is a syndrome characterized by the presence of an accessory pathway that skipping A-V node may lead the electrical stimulus from the atrium directly to the ventricle. Some studies reported the finding of myocardial dyskinesia in the segments precociously activated by the accessory pathway, at echocardiogram and at nuclear cardiac study. Soria et al. reported, in 1985, an increased incidence of dilative cardiomyopathy in patients with WPW. The pathophysiological pathway that leads to ventricular dilation may be due to the increase of end-diastolic pressure secondary to a tachycardia-induced cardiomyopathy. Tachycardia-induced cardiomyopathy is usually secondary to…
Asymptomatic ventricular pre-excitation in children.
2009
ASYMPTOMATIC VENTRICULAR PREEXCITATION IN CHILDREN OBJECTIVE: This retrospective study was planned for a good risk assessment of asymptomatic patients affected by ventricular pre-excitation. METHODS: From 1985 to 2007, 124 patients with an atrioventricular pathway (electrocardiographic signs of ventricular pre-excitation) were admitted to our cardiology division. The average age was 7 years (range 1 month to 18 years). The mean follow-up period in the whole population of patients was 4.2 years (range 1-13 years). Four patients were lost during the follow-up. During this period, all patients remained in good health. In all of them, we performed a Holter evaluation every year. An intermittent…
