Dextrocardia Overview
Learn About Dextrocardia
Dextrocardia is a condition in which the heart is pointed toward the right side of the chest. Normally, the heart points toward the left. The condition is present at birth (congenital).
Cyanotic heart defect - dextrocardia; Congenital heart defect - dextrocardia; Birth defect - dextrocardia
During the early weeks of pregnancy, the baby's heart develops. Sometimes, it turns so that it points to the right side of the chest instead of the left side. The reasons for this are unclear.
There are several types of dextrocardia. Many types involve other defects of the heart and abdomen area.
In the simplest type of dextrocardia, the heart is a mirror image of the normal heart and there are no other problems. This condition is rare. When this occurs, the organs of the abdomen and the lungs will often also be arranged in a mirror image. For example, the liver will be on the left side instead of the right.
Some people with mirror-image dextrocardia have a problem with the fine hairs (cilia) that filter the air going into their nose and air passages. This condition is called Kartagener syndrome.
In the more common types of dextrocardia, other heart defects are also present. The most common of these include:
- Double outlet right ventricle (the aorta connects to the right ventricle instead of to the left ventricle)
- Endocardial cushion defect (the walls separating all 4 chambers of the heart are poorly formed or absent)
- Pulmonary stenosis (narrowing of the pulmonary valve) or atresia (pulmonary valve does not form properly)
- Single ventricle (instead of two ventricles, there is a single ventricle)
- Transposition of the great vessels (the aorta and pulmonary artery are switched)
- Ventricular septal defect (hole in the wall that separates the right and left ventricles of the heart)
The abdominal and chest organs in babies with dextrocardia may be abnormal and may not work correctly. A very serious syndrome that appears with dextrocardia is called heterotaxy. In this condition, many of the organs are not in their usual places and may not work properly. For example, the spleen may be completely missing. The spleen is an important part of the immune system, so babies born without this organ are in danger of severe bacterial infections and death. In another form of heterotaxy, several small spleens exist, but they may not work correctly.
Heterotaxy may also include:
- Abnormal gallbladder system
- Problems with the lungs
- Problems with the structure or position of the intestines
- Severe heart defects
- Abnormalities of the blood vessels
Possible risk factors for dextrocardia include a family history of the condition.
There are no symptoms of dextrocardia if the heart is normal.
Conditions that may include dextrocardia may cause the following symptoms:
- Bluish skin (cyanosis)
- Difficulty breathing
- Failure to grow and gain weight
- Fatigue
- Yellow skin and eyes (jaundice)
- Pale skin (pallor)
- Repeated sinus or lung infections
A complete mirror image dextrocardia with no heart defects requires no treatment. It is important, however, to let your child's provider know the heart is on the right side of the chest. This information can be important in some exams and tests.
The type of treatment needed depends on the heart or physical problems the infant may have in addition to dextrocardia.
If heart defects are present with dextrocardia, the baby will most likely need surgery. Babies who are very ill may need to take medicines before they can have surgery. These medicines help the baby grow larger so surgery is easier to perform.
Medicines include:
- Water pills (diuretics)
- Medicines that help the heart muscle pump more forcefully (inotropic agents)
- Medicines that lower blood pressure and ease the workload on the heart (ACE inhibitors)
The baby might also need surgery to correct problems in the organs of the abdomen.
Children with Kartagener syndrome will need repeated treatment with antibiotics for sinus and lung infections.
Children with a missing or abnormal spleen need long-term antibiotics.
All children with heart defects may need to take antibiotics before surgeries or dental treatments.

Babies with simple dextrocardia have a normal life expectancy and should have no problems related to the location of the heart.
When dextrocardia appears with other defects in the heart and elsewhere in the body, how well the baby does depends on the severity of the other problems.
Babies and children without a spleen may have frequent infections. This is at least partially preventable with daily antibiotics.
Complications depend on whether dextrocardia is part of a larger syndrome, and whether other problems exist in the body. Complications include:
- Blocked intestines (due to a condition called intestinal malrotation)
- Death
- Heart failure
- Infection (heterotaxy with no spleen)
- Infertility in males (Kartagener syndrome)
- Repeated pneumonias (Kartagener syndrome)
- Repeated sinus infections (Kartagener syndrome)
Contact your provider if your baby:
- Seems to get frequent infections
- Does not seem to gain weight
- Tires easily
Seek emergency care if your baby has:
- A bluish color to the skin
- Trouble breathing
- Yellow skin
Some syndromes that include dextrocardia may run in families. If you have a family history of heterotaxy, talk to your provider before becoming pregnant.
There are no known ways to prevent dextrocardia. However, avoiding the use of illegal drugs (especially cocaine) before and during pregnancy may lower the risk of this problem.
Talk to your provider if you have diabetes. This condition may contribute to your risk of having a child with certain forms of dextrocardia.
Summary: Primary Ciliary Dyskinesias (PCD) are rare, autosomal recessive respiratory diseases, due to a defect in mucociliary clearance linked to abnormalities in the structure and/or function of the cilia. The variety of ciliary abnormalities identified reflects the genetic heterogeneity of PCDs. The thirty or so genes currently implicated explain the pathology in about half of the patients. PCDs are char...
Summary: The Ear-Nose-Throat (ENT) Prospective International Cohort of patients with Primary Ciliary Dyskinesia (EPIC-PCD) is a prospective observational clinical cohort study, set up as a multinational multi-centre study. It is embedded into routine patient care of participating reference centres for PCD and patients keep being managed according to local procedures and guidelines.
