Ultra-low-temperature cryoablation combined with preprocedural imaging and magnetic-based 3D mapping provides a state-of-the-art approach for ventricular tachycardia ablation.
Case Report
Does ultra-low-temperature cryoablation guided by advanced 3D mapping and preprocedural imaging terminate incessant ventricular tachycardia in a patient with prior myocardial infarction?
Ultra-low-temperature cryoablation guided by advanced 3D mapping and preprocedural imaging successfully terminated incessant ventricular tachycardia without complications in a single patient.
Key Teaching Points•Preprocedural imaging with ADAS 3D software (Galgo Medical S.L., Barcelona, Spain) can create a 3-dimensional model of the heart derived from magnetic resonance imaging and computed tomography.•Ensite X’s VoXel Mode (St Jude Medical, St Paul, MN) can create an electroanatomical map using magnetic-based coordinates.•The Adagio Medical VT Cryoablation System (Adagio Medical, Inc, Laguna Hills, CA) uses “near-critical” nitrogen refrigerant (T ≈ -196°C) and has been shown to produce durable transmural lesions. •Preprocedural imaging with ADAS 3D software (Galgo Medical S.L., Barcelona, Spain) can create a 3-dimensional model of the heart derived from magnetic resonance imaging and computed tomography.•Ensite X’s VoXel Mode (St Jude Medical, St Paul, MN) can create an electroanatomical map using magnetic-based coordinates.•The Adagio Medical VT Cryoablation System (Adagio Medical, Inc, Laguna Hills, CA) uses “near-critical” nitrogen refrigerant (T ≈ -196°C) and has been shown to produce durable transmural lesions.
Liebregts et al. (Fri,) conducted a case report in Ventricular tachycardia. Ultra-low-temperature cryoablation with preprocedural imaging and 3D mapping was evaluated. Ultra-low-temperature cryoablation combined with preprocedural imaging and magnetic-based 3D mapping provides a state-of-the-art approach for ventricular tachycardia ablation.
