Type

Case Report

Structured PICO

Does ultra-low-temperature cryoablation guided by advanced 3D mapping and preprocedural imaging terminate incessant ventricular tachycardia in a patient with prior myocardial infarction?

Population

A 75-year-old man with incessant monomorphic ventricular tachycardia despite amiodarone treatment, with a history of complicated PCI, emergency CABG, and secondary prevention ICD implantation.

Intervention

Ultra-low-temperature cryoablation using the Adagio Medical VT Cryoablation System (two 2-minute freezes at 9 ablation sites, total freeze time 36 minutes), guided by preprocedural imaging (ADAS 3D) and magnetic-based 3-dimensional mapping (Ensite X VoXel Mode).

Outcome

Non-inducibility of clinical ventricular tachycardia post-ablationsurrogate

Ultra-low-temperature cryoablation guided by advanced 3D mapping and preprocedural imaging successfully terminated incessant ventricular tachycardia without complications in a single patient.

Abstract

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.
