Cryoablation of a left coronary cusp ventricular tachycardia
Statistics from Altmetric.com
An otherwise healthy 19-year-old woman presented with a history of palpitations. A 12-lead ECG demonstrated runs of monomorphic, non-sustained ventricular tachycardia (VT) with left bundle-branch block morphology, right-axis deviation, suggesting an idiopathic VT from a coronary cusp (figure 1, panel B).1 Echocardiography demonstrated a structurally and functionally normal heart. She was admitted for electrophysiological evaluation and catheter ablation.
