Thrombolysis and embolectomy in treatment of acute stroke as a bridge to open-heart resection of giant cardiac myxoma: A case report.

Background: Cardiac embolism is a common cause of ischemic stroke in young adults. Neurological complications associated with atrial myxoma most frequently include cerebral infarct due to embolus. Early complete resection of giant cardiac myxoma is the key to its treatment and prevention of stroke recurrence.

Case Summary: A 42-year-old, previously healthy woman was admitted to the hospital with sudden-onset inability to speak and right-sided hemiplegia. While sweeping the floor 2 h prior to hospital admission, the patient developed sudden inability to express herself or understand what others were saying, accompanied by dyskinesia of the right limb, inability to walk or hold objects, and involuntary choreiform movements of the left upper limb. The patient was diagnosed with cerebral embolism and cardiac myxoma, complicated by left middle cerebral artery occlusion. The acute stroke was treated with intravenous thrombolytic therapy and arterial embolectomy as a bridging therapy to open resection of left atrial cardiac myxoma. The patient condition improved remarkably following initial thrombolysis and embolectomy and subsequently underwent emergency open resection of the atrial cardiac myxoma. She had no recurrence during 1-year follow-up.

Conclusion: Strong consideration should be given to urgent intravenous thrombolysis (rt-PA, alteplase) in young adult stroke patients at the time of hospital admission. The present case demonstrated a highly successful outcome that combined thrombolysis and arterial embolus retrieval as a bridge to early complete resection of a giant cardiac myxoma for both stroke treatment and recurrence prevention.
