Insights
Painless type A aortic dissection can be life-threatening, often leading to delayed diagnosis and poor outcomes. This case highlights the importance of considering aortic dissection even in asymptomatic patients.
Area of Science:
- Cardiology
- Vascular Surgery
Background:
- Aortic dissection is a critical vascular emergency with high mortality.
- Stanford classification categorizes dissections into Type A and Type B based on tear location.
- A significant percentage of patients die before hospital arrival or within 30 days of diagnosis.
Observation:
- A 53-year-old male with hypertension, sleep apnea, and diabetes presented with chest pain but was asymptomatic upon arrival.
- Initial workup suggested Non-ST Elevated Myocardial Infarction (NSTEMI) and aortic regurgitation.
- Computed tomography angiography (CTA) confirmed acute type A ascending aortic dissection.
Findings:
- The patient underwent an emergent Bentall procedure for the ascending aortic dissection.
- The patient tolerated the surgery well and is recovering.
- This case underscores the challenge of diagnosing aortic dissection when it presents without typical symptoms.
Implications:
- Emphasizes the critical need for heightened clinical suspicion for aortic dissection in atypical presentations.
- Highlights the potential for delayed diagnosis and adverse outcomes in painless aortic dissection.
- Underscores the importance of advanced imaging like CTA in confirming the diagnosis and guiding timely surgical intervention.
Abstract:
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.
