Core Tip
Core Tip: Premature ventricular contractions from left ventricular summit could be challenging to ablate due to anatomical reasons. New irrigation technologies, like the TactiFlex catheter, could facilitate deeper radiofrequency penetration and thus increase success in the ablative treatment. Late premature ventricular contractions elimination could be due to the porous flexible distal tip design of the TactiFlex catheter that allows deeper radiofrequency penetration in the myocardium due to a greater adhesion of the saline irrigation system to tissue. It is reasonable to assume that this new technology makes lesions more transmu-ral, determining a delayed lesion maturation, thus not limited to the duration of energy delivery.
