The Janus Heads of ventricular Tachycardia: Single-circuit with dual exits
In the setting of ischemic heart disease (IHD), ventricular tachycardia (VT) commonly originates from areas of incomplete scar tissue. High-density electroanatomic mapping has enhanced our understanding of VT circuits, predominantly characterised by dense scar and surviving myocyte bundles. We prese...

| Summary: | In the setting of ischemic heart disease (IHD), ventricular tachycardia (VT) commonly originates from areas of incomplete scar tissue. High-density electroanatomic mapping has enhanced our understanding of VT circuits, predominantly characterised by dense scar and surviving myocyte bundles. We present a case of a 58-year-old male with IHD and sustained monomorphic VT, successfully treated with radiofrequency ablation following high-density mapping and entrainment techniques. Two inducible VT phenotypes were identified, with ablation at one site effectively terminating both VT morphologies. This case illustrates the importance of precise circuit localisation and targeted ablation in managing post-infarction VT, leading to a satisfactory patient outcome. |
