Abstract
Background: Basal crux ventricular tachycardia (VT) is traditionally considered an idiopathic arrhythmia. However, its occurrence in patients with structural heart disease, especially ischemic heart disease (IHD), is often under recognised.
Case summary: We report two patients with a history of myocardial infarction who presented with basal crux VT. In both cases, VT was rendered non-inducible, and both patients experienced recovery of their left ventricular ejection fraction (LVEF), indicating a significant burden of arrhythmia-induced cardiomyopathy.
Discussion: It is unclear whether IHD is purely coincidental or contributes to the underlying substrate promoting arrhythmogenesis.
Conclusion: Basal crux VT can occur in patients with IHD and may resemble idiopathic epicardial VT. Ablation in the proximal middle cardiac vein (MCV) may be potentially curative.
