Ultra-high density mapping with the Rhythmia system can rapidly identify critical VT circuits in hemodynamically unstable patients.
Herein, we report a 47-year-old woman with ischemic cardiomyopathy who underwent ablation therapy due to an electrical storm without any triggers. The voltage mapping in sinus rhythm with the Rhythmia system and Orion catheter displayed several LAVAs in and around the anteroapical scar area. Although the patient did not tolerate the induced clinical ventricular tachycardia, which was reproductively induced, 35-second-mapping in the scar zone with the Orion catheter demonstrated the VT circuit with the critical isthmus. This report shows the possibility of the new ultra-high density mapping system in a specific ischemic VT patient.
Takigawa et al. (Wed,) conducted a case report in Ischemic cardiomyopathy with recurrent ventricular tachycardia (n=1). Rhythmia mapping system with Orion catheter was evaluated on Successful mapping of VT circuit. The Rhythmia ultra-high density mapping system successfully delineated the electrical circuit of a hemodynamically unstable and recurrent ventricular tachycardia in 35 seconds.
