Signs and symptoms
In the absence of congenital heart defects, individuals with situs inversus are homeostatically normal, and can live standard healthy lives, without any complications related to their medical condition. There is a 5–10% prevalence of congenital heart disease in individuals with situs inversus totalis, most commonly transposition of the great vessels. The incidence of congenital heart disease is 95% in situs inversus with levocardia.Many people with situs inversus totalis are unaware of their unusual anatomy until they seek medical attention for an unrelated condition, such as a rib fracture or a bout of appendicitis. The condition may also be discovered during the administration of certain medicines or during tests such as a barium meal or enema. The reversal of the organs may then lead to some confusion, as many signs and symptoms will be on the atypical side. For example, if an individual with situs inversus develops appendicitis, they will present to the physician with lower left abdominal pain, since that is where their appendix lies. Thus, in the event of a medical problem, the knowledge that the individual has situs inversus can expedite diagnosis. People with this rare condition should inform their doctors before an examination, so the doctor can redirect their search for heart sounds and other signs. Wearing a medical identification tag can help inform health care providers in the event the person is unable to communicate.Situs inversus also complicates organ transplantation operations as donor organs will more likely come from situs solitus (normal) donors.
Such a procedure is unnecessary, given that situs inversus rarely causes any additional symptoms. No treatment, medical or surgical, is prescribed for situs inversus patients, with medical professionals instead treating any other symptoms the patient may have with awareness of the unique anatomy of the patient. Epidemiology
Situs inversus is very rare, affecting 0.01% of the population. This is equivalent to 1 in 10,000 people. History
Dextrocardia (the heart being located on the right side of the thorax) was seen and drawn by Leonardo da Vinci, and then recognised by Marco Aurelio Severino in 1643. Situs inversus was first described more than a century later by Matthew Baillie. Etymology
The term situs inversus is a short form of the Latin phrase situs inversus viscerum, meaning "inverted position of the internal organs". Notable cases
Notable individuals with documented cases of situs inversus include:

Enrique Iglesias, a Spanish singer, songwriter, actor and record producer. Catherine OHara, Canadian-American actress, writer and comedian. Randy Foye, an American basketball player in the NBA. He has suffered no discernible complications, and the condition is not expected to affect his career as a professional athlete, as all his organs are in reverse. Ginggaew Lorsoongnern, a Thai convict executed by firing squad. Her condition was discovered after she was shot in the left side of her chest and survived. After waking up in the morgue she was taken back and executed. Tim Miller, director of the Ashtanga Yoga Center in Carlsbad, California.
