Safe thrombolysis during pregnancy for recurrent acute ischaemic stroke due to concomitant isolated left ventricular non-compaction and bilateral foetal posterior communicating arteries

Isolated left ventricular non-compaction (ILVNC) is a rare congenital cardiomyo-pathy and is associated with arrhythmias, heart failure and thromboembolism including ischaemic stroke. Pregnancy is a relative contraindication to thrombolysis for acute ischae-mic stroke, although case reports suggest the treatment can be given in selected cases. We report a case of recurrent cryptogenic strokes in a 36-year-old female who was thrombolysed with good outcome at 37 weeks’ gestation and was eventually found to have ILVNC as the cause. She had a predilection to recurrent posterior circulatory strokes due to foetal posterior communicating arteries. To our knowledge this is the first case report of safe thrombolysis for acute ischaemic stroke in pregnancy caused by ILVNC.
