Recurrent cryptogenic stroke in young adult linked to congenital left ventricular diverticulum

A 47-year-old man had an acute ischemic stroke (IS); brain MRI revealed multiple silent old IS (figure 1A). A comprehensive workup, including prolonged cardiac monitoring (cumulated duration of 25 days) and cardiac transthoracic/transesophageal echography, was negative. Eleven months later, despite statin and aspirin therapy, a new symptomatic embolic IS of undetermined source occurred (figure 1B). Cardiac MRI1 revealed a left apical dyskinetic saccular evagination (figure 2, A–C) consistent with a congenital left ventricular diverticulum confirmed on left ventriculography (figure 2D) and the presumed source of recurrent embolic IS.2 No IS occurred after 30 months of warfarin therapy.
