Cryoablation of arrhythmias from the interventricular septum: initial experience with a new biventricular approach
J Krafchek, GM Lawrie and CR Wyndham
The use of cryothermy in addition to other newer surgical techniques has
improved the outcome for patients undergoing operation for ventricular
tachycardia. However, the depth to which the cryothermic lesions penetrate
the myocardium may be a limiting factor in some situations. In an attempt
to overcome this problem, we applied cryothermia from both sides using a
new biventricular approach in five patients with documented
interventricular septal foci. The advantages, disadvantages, and possible
indications for the use of this approach are discussed, as are methods for
avoiding potential complications.
