A vascular ring is a malformation of the aortic arch anatomy, where vessels partly or completely encircle the trachea and esophagus. A normal heart with a normal aortic arch is shown on the left. An example of a vascular ring — a double aortic arch — is shown on the right.
Can you live with a vascular ring?
Not all patients with vascular rings need surgery. In fact, some people without symptoms may live their entire lives not even realizing that they have a vascular ring. More often, however, the condition causes a variety of respiratory and digestive woes.
What causes a vascular ring?
A vascular ring occurs when the aorta (the large artery that carries oxygenated blood out of the heart) or its branches form a complete ring around the trachea (the tube that carries air to the lungs) and the esophagus (the tube that carries food to the stomach).
What are the symptoms of a vascular ring?
What are the symptoms of a vascular ring?
- stridor (noisy breathing)
- wheezing or cough.
- respiratory distress.
- difficulty feeding when you introduce solid foods.
- swallowing difficulties (dysphagia)
- gastroesophageal reflux (GERD)
- respiratory infections.
How rare is a vascular ring?
Vascular ring is rare. It accounts for less than 1% of all congenital heart problems. The condition occurs as often in males as females. Some infants with vascular ring also have another congenital heart problem.
Is vascular ring genetic?
Background. Vascular rings have not been described to be heritable outside of syndromic genetic conditions, most classically 22q11 deletion syndrome. The TBX1 gene is located within the critical region of 22q11 and is associated with cardiac defects.
Is a vascular ring a heart defect?
Normal heart and heart with vascular ring
Vascular rings are malformations of the aortic arch in the main blood vessel that leads from the heart. Because of the malformation, the aortic arch and its branches partly or completely encircle the windpipe (trachea), the esophagus or both.
How do you rule out a vascular ring?
The following tests can help diagnose vascular ring:
- Chest x-ray.
- Computed tomography (CT) scan of the heart and major blood vessels.
- Camera down the throat to examine the airways (bronchoscopy)
- Magnetic resonance imaging (MRI) of the heart and major blood vessels.
- Ultrasound examination (echocardiogram) of heart.
Can you see a vascular ring on xray?
Because patients with vascular rings and slings often present with respiratory symptoms, the imaging evaluation often starts with a two-view chest radiograph. In up to 95% of patients with a vascular ring/sling, an abnormality is visible on chest radiographs.
Can a vascular ring come back after surgery?
The majority of patients having surgical intervention for a vascular ring have resolution of their symptoms. However, 5% to 10% of these patients develop recurrent symptoms related either to airway or esophageal compression and may require reoperation.
What side is the aortic arch on?
The aorta forms an arch in the chest and usually travels inside the chest on the left side. In some people the arch of the aorta turns to the right and travels down the chest on the right side. This is known as a right aortic arch.
How common is right sided aortic arch?
A right-sided aortic arch is thought to occur in approximately ~0.1% (range 0.05-0.2%) of the population.
What is heart ring?
The heart ring installation serves to improve blood flow and oxygen by enlarging the cavity of the blood vessels that are narrowed or clogged. Coronary heart disease is characterized by narrowing to blockage of blood vessels which causes patients to experience chest pain.
How rare is a double aortic arch?
Vascular rings are a rare form of aortic arch anomaly resulting in trachea-esophageal compression and represent 1%-3% of all congenital heart diseases [1]. Double aortic arch (DAA) constitutes about 46%-76% of all symptomatic congenital vascular rings [2].
What does truncus arteriosus mean?
Truncus arteriosus is a birth defect of the heart. It occurs when the blood vessel coming out of the heart in the developing baby fails to separate completely during development, leaving a connection between the aorta and pulmonary artery.
What is the functions of aorta?
The aorta is the main artery that carries blood away from your heart to the rest of your body. The blood leaves the heart through the aortic valve. Then it travels through the aorta, making a cane-shaped curve that allows other major arteries to deliver oxygen-rich blood to the brain, muscles and other cells.
What is an aberrant left subclavian artery?
Abstract. Background: Left aberrant subclavian artery (LASA), is a type of right aortic arch (RAA) branching, which takes-off distally to the right subclavian artery and usually crosses behind the esophagus to the left upper limb.
Is a left sided aortic arch normal?
A left aortic arch and aberrant right subclavian artery are often considered a normal variant and not a true vascular ring because of the typical absence of a right-sided ductus arteriosus or ligamentum arteriosum.
Is a double aortic arch hereditary?
Causes. Little is known regarding the exact causes of aortic arch anomalies. However, the association with chromosome 22q11 deletion (DiGeorge Syndrome) implies that a genetic component is likely in certain cases. Esophageal atresia also occurs in some patients with double aortic arch.
How ring is placed in heart?
In annuloplasty, the surgeon tightens or reinforces the ring around a valve in the heart. An annuloplasty is a procedure to tighten or reinforce the ring (annulus) around a valve in the heart. It may be done during other procedures to repair a heart valve.
What is dysphagia Lusoria?
Dysphagia lusoria is a term used to describe dysphagia as a consequence of vascular compression of the oesophagus. Bayford coined the term itself meaning “freak or jest of nature” in 1761 in describing a case of longstanding dysphagia leading to emaciation and eventual death of a 62-year old female patient.
What is Ligamentum Arteriosum?
The ligamentum arteriosum is the embryologic remnant of the ductus arteriosus, which serves to shunt blood away from the lungs during fetal development and typically closes near the time of birth.
What is aberrant right subclavian artery?
Abstract. Aberrant right subclavian artery (ARSA) is a rare anomaly, in which the right subclavian artery arises directly from the aortic arch instead of originating from the brachiocephalic artery. This anomaly should be taken into consideration during surgical procedures around esophagus, such as esophagectomy.
Where is the innominate artery?
The brachiocephalic artery (or brachiocephalic trunk or innominate artery) is an artery of the mediastinum that supplies blood to the right arm and the head and neck.
What is a double aortic arch?
Double aortic arch is an abnormal formation of the aorta, the large artery that carries blood from the heart to the rest of the body. It is a congenital problem, which means that it is present at birth.
Is right aortic arch a CHD?
Right aortic arch with mirror image branching is strongly associated with CHD in up to 98% of cases, including tetralogy of Fallot, truncus arteriosus, tricuspid atresia, and transposition of the great arteries with pulmonary valve stenosis.
How serious is right aortic arch?
In general, the isolated right aortic arch is a benign lesion. Right aortic arch and left pulmonary artery anomalies are more difficult to identify and may require more extensive evaluation and intervention. Vascular rings associated with right aortic arch anomalies are intervened upon for symptomatic benefit.
Do birds have right aortic arch?
In birds, the systemic arch is formed by the fourth right aortic arch and the anterior arteries which are supplying the head region (internal carotid arteries, common carotid, brachiocephalic) gives rise to the blood vessels in the forelimbs (subclavian arteries).
What causes a right sided aortic arch?
Right aortic arch occurs due to the persistence of the right branch with the regression of the left branch. This means that the aorta arches to the right side. It is most commonly a normal variant.
Is persistent right aortic arch hereditary?
These ring anomalies are sometimes completely benign but sometimes they entrap vital organs with serious consequences1. While these abnormalities are inherited, the exact hereditary mechanism is unknown. The condition is most common in German Shepherds and Irish Setters but can occur in other breeds2,3.
What is right sided aorta?
Right-sided aortic arch is a type of aortic arch variant characterized by the aortic arch coursing to the right of the trachea.
What are the disadvantages of stents?
The risk of re-narrowing of the artery is higher when bare-metal stents are used. Blood clots. Blood clots can form within stents even after the procedure. These clots can close the artery, causing a heart attack.
Does a stent clear the blockage?
Angioplasty is a procedure to open narrowed or blocked blood vessels that supply blood to the heart. These blood vessels are called the coronary arteries. A coronary artery stent is a small, metal mesh tube that expands inside a coronary artery. A stent is often placed during or immediately after angioplasty.
Which part of the body does angiography deal with?
Common types include: coronary angiography – to check the heart and nearby blood vessels. cerebral angiography – to check the blood vessels in and around the brain. pulmonary angiography – to check the blood vessels supplying the lungs.
How many people have a double aortic arch?
Generally, incidence of double aortic arch and vascular rings is unknown, although vascular rings comprise an estimated 1% of cardiovascular malformations that are managed surgically. In most surgical series, 45-65% of patients undergoing repair of a vascular ring have a double aortic arch.
What is the aortic knuckle?
The aortic knuckle represents the left lateral edge of the aorta as it arches backwards over the left main bronchus. The contour of the descending thoracic aorta can be seen in continuation from the aortic knuckle.
How is double aortic arch diagnosed?
The following tests can help diagnose double aortic arch:
- Chest x-ray.
- Scans that create cross-sectional images of the body (CT or MRI scan)
- Ultrasound examination of the heart (echocardiography)
- X-ray using a substance that outlines the esophagus (barium swallow)
Can a baby survive with truncus arteriosus?
If truncus arteriosus isn’t repaired by surgery, most babies won’t survive. Surgery to repair it is usually successful, and most babies recover well. However, some will need more surgeries as they grow.
Is truncus arteriosus life threatening?
As a result of truncus arteriosus, oxygen-poor blood that should go to the lungs and oxygen-rich blood that should go to the rest of the body are mixed. This creates severe circulatory problems. Untreated, truncus arteriosus can be fatal.
Can truncus arteriosus be cured?
Truncus arteriosus must be treated through surgery. While your baby is waiting for surgery, he or she may need to take medications to reduce fluid in the lungs and have high-calorie feedings to build strength. Most babies with truncus arteriosus need surgery in the first few days or weeks of life.
What are the symptoms of aorta problems?
Signs and symptoms that your thoracic aortic aneurysm has burst include:
- Sudden, intense and persistent chest or back pain.
- Pain that radiates to your back.
- Trouble breathing.
- Low blood pressure.
- Loss of consciousness.
- Shortness of breath.

How do you know if you have problems with your aorta?
If you have an enlarging abdominal aortic aneurysm, you might notice: Deep, constant pain in the belly area or side of the belly (abdomen) Back pain. A pulse near the bellybutton.
Can you feel pain in your aorta?
Deep, Aching Pain
Aortic aneurysms can occur in the chest or abdomen (stomach area) and are usually accompanied by a deep pain that some refer to as “gnawing” in nature. The pain often radiates into the shoulder blade, back, or flank.
