It results in a mutation in the Fibrillin-1 protein gene. We present a case of  Marfan's syndrome in a young adult with life-threatening, sudden onset of chest pain secondary to a non-ST elevation myocardial infarction (NSTEMI) in the setting of an aortic pseudoaneurysm. Taking into consideration potential life-threatening underlying processes, a thorough and detailed methodology must be undertaken when encountering chest pain in a Marfan's syndrome patient. This case highlights the importance of utilizing a multi-disciplinary approach to the complexities of Marfan syndrome.
