Determinants of lesion dimensions during transcatheter microwave ablation.
Transcatheter microwave ablation is a novel technique for treating cardiac arrhythmias. ⋯ This study demonstrated that lesions size with transcatheter microwave ablation can be controlled by adjusting targeted temperature, energy application duration, and antenna length. A targeted temperature of 80 degrees C for more than 150 seconds should provide optimal lesion dimensions and lower risk of surface dessication or charring.

Case ReportsCoexisting idiopathic left ventricular tachycardia and atrioventricular reentrant tachycardia in a patient with wolff-Parkinson-white syndrome.
We report a patient with Wolff-Parkinson-White syndrome who presented with two distinct tachycardias that represented atrioventricular reentrant tachycardia utilizing left lateral accessory pathway (AP) and idiopathic left ventricular tachycardia (ILVT). Two tachycardias with a complete separate mechanism occurred spontaneously as well as following atrial or ventricular pacing. Successful ablation of the left AP and ILVT resulted in a cure of the double tachycardia.
