Masson Tumor in the Left Atrial Appendage Presenting as Cardioembolic Cerebral Infarction.

A 70-year-old woman presented with aphasia caused by acute infarction in the left middle cerebral artery. Cardiac investigation revealed progressively increasing mobile mass in the left atrial appendage over 2 months (from 9 to 15 mm).

Acute ischemic stroke following cardioversion in a patient receiving dabigatran.

Objective: To report a case of acute ischemic stroke following electrical cardioversion in a patient currently anticoagulated with dabigatran 150 mg twice daily.

Case Summary: A 74-year-old man, who had been adherent with more than 6 weeks of dabigatran 150 mg twice daily therapy, presented with a dense left-sided hemiparesis 72 hours following a repeat electrical cardioversion.

Embolic stroke due to a left atrial thrombus two years after placement of an atrial septal defect closure device.

A 29-year-old woman who had undergone closure of a secundum-type atrial septal defect using the Amplatzer device 2 years previously developed acute and progressive altered mentation. Initial clinical and imaging data confirmed the diagnosis of multiple cerebral, cerebellar and brain stem emboli, and infarcts. She was treated urgently with an intra-arterial thrombolytic agent with only minimal improvement.
