To illustrate the feasibility of ventricular tachycardia (VT) ablation assisted by single photon emission computed tomography (SPECT)-multidetector (MDCT) computed tomography 'fusion' image guidance.
A patient with ischaemic cardiomyopathy and recurrent VT underwent catheter ablation. Prior to the procedure, SPECT and MDCT had been obtained. A combined ('fusion') image was created, and this image was registered to the operative field using a commercial catheter navigation system. There was a close anatomic and electrophysiological correspondence between the left ventricular electroanatomic map obtained in the operating theatre and the fusion image.
If accuracy of this technique can be confirmed, fusion image guidance may offer a significant value during catheter ablation of VT, including improved substrate detail and procedure abbreviation.
