Posttraumatic Papillary Muscle VT . After being struck by a car at the age of 7, an otherwise healthy boy developed recalcitrant, albeit hemodynamically, well‐tolerated ventricular tachycardia. An electrophysiological study with 3‐dimensional electroanatomic mapping was performed under transesophageal echocardiographic guidance at 10 years of age. Nonautomatic focal ventricular tachycardia was mapped to the left anterolateral papillary muscle, where it was successfully ablated. To our knowledge, this report represents the first description of papillary muscle ventricular tachycardia in a child, and of blunt thoracic trauma as a potential trigger.
