Where is the Sinotubular Junction?
ascending aorta
The sinotubular junction is the region of the ascending aorta between the aortic sinuses (of Valsalva) and where the normal tubular configuration of the aorta is attained. The superior attachments of the aortic valvar leaflets demarcate the level of the sinotubular junction.
What are symptoms of aortic ectasia?
Signs and symptoms that a thoracic aortic aneurysm has ruptured or dissected include:
- Sharp, sudden pain in the upper back that spreads downward.
- Pain in the chest, jaw, neck or arms.
- Difficulty breathing.
- Low blood pressure.
- Loss of consciousness.
- Shortness of breath.
- Trouble swallowing.
What is cornea ectasia?
In corneal ectasia, LASIK or PRK procedures remove too much tissue from the cornea, and causes a new form of astigmatism. The cornea becomes excessively thin and weak, and won’t be able to hold the normal eye pressure. Thus, it starts bulging out.
What is difference between aneurysm and ectasia?
Introduction. Coronary artery aneurysms and ectasia are characterized by an abnormal dilatation of a coronary artery. The term ectasia is reserved to mean a diffuse dilatation of a coronary artery, and an aneurysm is a focal dilatation of the vessel (1).
What causes aortic ectasia?
The presence of coronary artery ectasia (CAE) is influenced by genetic factors and related to the presence of aneurysms in other vascular beds. Bicuspid aortic valve (BAV) disease is frequently accompanied by ascending aortic aneurysm.
Is corneal ectasia serious?
Corneal ectasia is rare, but very severe. It is a complication of corrective surgery procedures to the eye.
Can corneal ectasia be treated?
Treatments. Ectasia can usually be treated. Treatments for ectasia are similar to those used to treat a condition called keratoconus (another distortion of the eye’s shape). Thanks to advancements in technology, some patients with ectasia can now benefit from a procedure called corneal collagen cross-linking (CXL).
When does aortic root dilation need surgery?
Aortic Root Surgery When operating because of bicuspid valve disease, an aortic root procedure is usually considered necessary if the root diameter is enlarged to 4 cm or greater. 2) If the valve is functioning well, surgical intervention is not considered until the diameter of the aorta exceeds 5cm.
When do you treat ascending aortic aneurysm?
As of today, it is recommended to offer prophylactic ascending aorta repair to patients without predisposing conditions other than hypertension when the aorta reaches 5.5 cm or if the growth rate exceeds 0.5 cm per year or if patient is undergoing another major cardiac surgery with an ascending aorta over 4.5 cm.
What should you not do with an ascending aortic aneurysm?
DON’T:
- Push, pull, bear down or lift anything heavier than 30 pounds (or 10 pounds for patients recovering from surgery).
- Get a tattoo or body piercing.
- Smoke (or be exposed to secondhand smoke) or use any other tobacco products.
- Shovel snow, chop wood, dig earth or use a sledgehammer or snow blower.
- Take illicit drugs.
