In general, anterior chest pain is more consistent with type A dissection while back pain was found to be more consistent with type B dissection. Ībrupt and severe chest and back pain are the most common presenting signs and symptoms for type A (79% vs. Furthermore, the study identified unique risk factors in this population including Marfan syndrome, bicuspid aortic valves, and larger aortic dimensions. A study utilizing the IRAD with a focus on younger patients (<40 years of age) revealed that this population constituted 7% of patients who suffered AAD. The most common risk factors for AAD include hypertension (76.6%), atherosclerotic disease (27%), prior cardiac surgery (16%), and Marfan syndrome (5%). Overall, type A dissection constitutes 67% of AAD. The International Registry of Aortic Dissection (IRAD) was established in 1996 to raise awareness and provide guidance in the diagnosis and treatment of this condition. It is for these reasons that this devastating condition requires a high index of suspicion to make the diagnosis and implement treatment strategies as quickly as possible. Furthermore, for every hour that AAD involving the ascending aorta (Sanford type A) is left untreated, mortality rate increases by 1%. The incidence of AAD is ~2.3 per 100,000 person-years with mortality rates greater than 50% within 30 days of diagnosis. Herein, we report an atypical presentation of AAD and clinical sequelae. As such, early diagnosis and aggressive management are essential in order to avoid life-threatening complications. Acute aortic dissection (AAD) is associated with unacceptably high mortality rate.
