As it is recessive genes that cause dextrocardia, an individual must inherit a copy of the abnormal gene from both parents to develop the condition. Dextrocardia affects an estimated 1 out of every 12,000 people . Dextrocardia situs inversus totalis affects approximately 1 out of every 10,000 children.

What gene causes dextrocardia?

Some people have dextrocardia with situs inversus as part of an underlying condition called primary ciliary dyskinesia. Primary ciliary dyskinesia can result from changes ( mutations ) in several different genes, including the DNAI1 and DNAH5 gene; however, the genetic cause is unknown in many families.

Is dextrocardia a birth defect?

Dextrocardia is a heart condition that makes the heart move out of its usual position. It points towards the right side of your chest instead of the left side. The condition is congenital, meaning that people are born with it, but it's rare.

How common is dextrocardia?

Dextrocardia is a very rare condition, and studies have revealed incidence rates of dextrocardia to be around 1 in 12000 pregnancies. [7] Kartagener syndrome has an incidence rate of about 1 in 30,000 live births, and situs inversus totalis was seen in around 50% of patients with primary ciliary dyskinesia.

Is situs inversus a genetic disorder?

Situs inversus is caused by an autosomal recessive genetic condition. An unaffected carrier mother and an unaffected carrier father have a 1 in 4 chance of having a child with situs inversus. Because many genetic steps would have to come together to cause situs inversus, the condition is rare.

Can dextrocardia be corrected?

Treating dextrocardia

Dextrocardia must be treated if it prevents vital organs from functioning properly. Pacemakers and surgery to repair septal defects can help the heart work normally.

Can you have dextrocardia without inversus?

In dextrocardia, the heart is on the right side of the thorax with or without situs inversus. When the heart is right sided with inverted atria, the stomach is right sided, and the liver is left sided, the combination is dextrocardia with situs inversus.

How is dextrocardia diagnosed on ECG?

4 In patients with dextrocardia, the standard 12-lead ECG will show marked right-axis deviation of the P wave and QRS complex, with lead I frequently demonstrating a largely negative QRS complex and inverted P and T waves. 5 The QRS complexes in leads aVR and aVL are reversed so that the R wave in lead aVR is positive.

What is ectopic cordis?

Ectopia cordis is a rare condition where a baby's heart is located either partially or totally outside the chest. Only 8 out of 1 million babies are born with ectopia cordis, and 90% of these babies are either stillborn or die within the first 3 days of life.

What is Heterotaxia?

Heterotaxy is a rare condition where many organs in the body can be formed abnormally, in the wrong position, or even missing. Many children with heterotaxy have complex heart defects, which are often the most challenging problems associated with heterotaxy.

Does dextrocardia require surgery?

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.

What is precordial?

Precordial means 'in front of the heart,' which is where a person feels the pain. It is also known as Texidor's twitch. While it can be painful, it will usually go away on its own, and it leaves no lasting impact.

What is DORV in cardiology?

Double outlet right ventricle (DORV) is a congenital heart defect. There is a malformation of the fetus heart in the womb leading to the right ventricle that has the two major arteries, namely the aorta and pulmonary artery arising from it.

Is Dextrocardia situs inversus rare?

Dextrocardia with Situs Inversus is a rare heart condition characterized by abnormal positioning of the heart. In this condition, the tip of the heart (apex) is positioned on the right side of the chest.

What is Kartagener's Syndrome?

Kartagener's syndrome is a rare, autosomal recessive genetic ciliary disorder comprising the triad of situs inversus, chronic sinusitis, and bronchiectasis. The basic problem lies in the defective movement of cilia, leading to recurrent chest infections, ear/nose/throat symptoms, and infertility.

Can people have flipped organs?

Situs inversus (also called situs transversus or oppositus) is a congenital condition in which the major visceral organs are reversed or mirrored from their normal positions. The normal arrangement of internal organs is known as situs solitus.

Can a baby survive ectopia cordis?

Unfortunately, the ectopia cordis survival rate is just 10%. Most babies born with hearts outside their bodies have severe intracardiac abnormalities are stillborn or die within the first few days of life. Those who survive require extensive surgeries and lifelong medical care delivered by a team of specialists.

Is Tinman Syndrome Real?

This case is fictitious and the described condition is not a real diagnosis.

Can you be born with an extra heart?

People with Wolff-Parkinson-White syndrome are born with an extra connection in the heart, called an accessory pathway, that allows electrical signals to bypass the atrioventricular node and move from the atria to the ventricles faster than usual.

Is Dextrocardia fatal?

Dextrocardia is a rare congenital condition where the heart points toward the right side of the chest instead of the left. The condition is usually not life-threatening, although it often occurs alongside more serious complications, such as heart defects and organ disorders in the abdomen.

How are limb leads placed in Dextrocardia?

Leads placement can be corrected according to mir- ror position, wherein the left lead is placed on the right arm, the right arm lead is placed on the left arm, and the V1 through V6 leads are placed in the V2, V1, and V3R through V6R positions.

How do you place electrodes for Dextrocardia?

Similar to a right-sided ECG, use the same physiological landmarks to place the 12-lead electrodes on the right side of the chest. Another consideration for treatment is the placement of pacer or defibrillator pads. Effectiveness of defibrillation would be limited if normal placement were utilized.

What is dextrocardia situs Solitus?

Dextrocardia refers to a heart positioned in the right side of the chest. Situs solitus describes viscera that are in the normal position, with the stomach on the left side; in situs inversus, the positions of the abdominal organs and viscera are reversed.

What is the difference between dextrocardia and Dextroposition?

Dextroposition describes a heart on the right with an apex to the left, secondary to extracardiac causes (right lung hypoplasia, pneumonectomy or diaphragmatic hernia). In contrast, dextrocardia results from cardiac chamber disarrangement.

What is a mirror-image dextrocardia?

Mirror-image dextrocardia is the most common form of cardiac malposition encountered and is almost always associated with situs inversus of the abdominal organs. The anatomic right ventricle is anterior to the left ventricle and the aortic arch curves to the right and posteriorly.
