Ascending Aortic Aneurysm

The ascending aorta is the main trunk of the aorta. From the aortic root, this section of the aorta travels up toward the head. An ascending aortic aneurysm is a medical condition characterized by an abnormal and potentially dangerous enlargement or bulging of the ascending aorta. It means that this segment of the aorta has weakened and expanded beyond its normal size. If left untreated, an ascending aortic aneurysm can continue to grow, potentially leading to serious and life-threatening complications such as rupture, dissection, and compression of nearby structures. 

Causes 

There are many potential causes of an ascending aortic aneurysm, including: 

  • Genetics and family history of aneurysms 
  • Connective tissue disorders, such as Marfan syndrome, Vascular Ehlers-Danlos syndrome, and Loeys-Dietz syndrome 
  • High blood pressure 
  • Smoking (leading to injury of the wall of the aorta) 
  • Age 
  • Atherosclerosis (hardening of the arteries) 
  • Bicuspid aortic valve, a congenital heart condition 
  • Infections affecting the aorta 
  • Trauma or injury to the aorta 

Symptoms  

Ascending aortic aneurysms often have no symptoms. Some possible aneurysm symptoms are: 

  • Dull chest pain 
  • Chest pain during exercise 
  • Shortness of breath 

Symptoms of a dissected or ruptured ascending aortic aneurysm include: 

  • Sharp chest pain, sometimes also felt in the back. 
  • Extreme shortness of breath 
  • Trouble swallowing 
  • Fainting/loss of consciousness

Diagnosis  

Ascending aortic aneurysms are typically diagnosed using the following imaging tests: 

  • Echocardiogram (ultrasound of the heart): An echocardiogram uses sound waves to create a picture of the heart and blood vessels 
  • Computed tomography (CT) scans use X-rays and computer technology to produce detailed images of the aorta. 
  • Magnetic resonance angiography (MRA) scans are a type of MRI that looks specifically at the body’s blood vessels.
