Successful right anteroseptal manifest accessory pathway cryoablation in a sixmonth infant with dyssynchrony-induced dilated cardiomyopathy

Özet

Ventricular preexcitation via an accessory pathway (AP) results in an asynchronous spread of ventricular depolarization that may lead to an abnormal regional wall motion and systolic dysfunction in patients with Wolff–Parkinson–White (WPW) syndrome, even without documented supraventricular tachycardia (1-3). It isknown that adults and children with preexcitation-associated cardiomyopathy can completely recover following resynchronization
