We report the case of a 72‐year‐old man with a nonsustained ventricular tachycardia and a history of palpitations. He had a severely deformed thorax since childhood due to spinal caries. An integrated computed tomography image of the outflow tract region from the CartoSound ® system revealed the detailed anatomical information around the origin of the tachycardia and that the left anterior descending coronary artery was very close (<10 mm) to the target site. We carefully ablated that site with a 3.5‐mm cooled‐tip catheter while confirming it in the sound view, and succeeded without any complications.
