Quiet & deadly: Painless aortic dissection.

Aortic dissection is a life-threatening condition that classically presents as a sudden, sharp pain with a ripping sensation. This disease is caused by a weakened area within the aortic arterial wall, which can be classified using the Stanford classifications into type A or type B dissections, depending on the location of the tear. It is described that 17.6% of patients died before arriving at the hospital, and 45.2% of patients died within 30 days of diagnosis (Melvinsdottir et al., 2016). However, 10% of patients present without pain, leading to delayed diagnosis. In this case, a 53-year-old male with prior history of hypertension, sleep apnea, and diabetes mellitus presented to the emergency department with complaints of chest pain earlier that day. However, he was asymptomatic on presentation. He had no cardiac history. He was admitted, and a subsequent workup was performed to rule out myocardial infarction. The following morning a slight bump in troponin consistent with a Non-ST Elevated Myocardial Infarction (NSTEMI) was noted. An echocardiogram was ordered and showed aortic regurgitation. This was followed by computed tomography angiography (CTA), which revealed acute type A ascending aortic dissection. He was transferred to our facility and underwent an emergent Bentall procedure. Ultimately, the patient tolerated the surgery well and is recovering. This case is essential because it emphasizes the painless presentation of type A aortic dissection. Mis- or undiagnosed, this condition often leads to death.
