Disappearance of local ventricular components during extrastimulus pacing after ultra-low-temperature cryoablation for ventricular tachycardia: a case report
Abstract Background Ultra-low-temperature cryoablation (ULTC) enables the creation of deep and potentially transmural myocardial lesions and is increasingly used for ventricular tachycardia (VT) substrate modification. However, the chronic electrophysiological properties of myocardium following extreme cryothermal inju...
