Stroke in the young: infective endocarditis due to mitral valve prolapse leading to acute ischemic stroke and subsequent hemorrhagic transformation.

Background: Stroke in young needs an individualized approach before considering thrombolysis. Here we present a case of undiagnosed mitral valve prolapse presenting with stroke due to associated infective endocarditis. Young stroke patients presenting with fever need a panoramic approach. This 39-year-old female with a background history of fever and loss of weight for two months presented to the emergency department with a history of altered sensorium and aphasia. The Magnetic Resonance Imaging (MRI) showed a hyperacute infarct. Hence, thrombolysis with alteplase was considered. Post thrombolysis, the patient had a parenchymal bleed. The diagnostic evaluation yielded stroke secondary to infective endocarditis because of undiagnosed mitral valve prolapse.

Conclusion: Mitral valve prolapse is not associated with stroke in young patients. However, the undiagnosed infective endocarditis and subsequent septic emboli led to an increased risk. Emergency physicians and intensivists should anticipate infective causes before considering thrombolysis, as the results could be counterproductive.
