Dextrocardia (from Latin dexter, meaning "right," and Greek kardia, meaning "heart") is a rare congenital condition in which the apex of the heart is located on the right side of the body. dextrocardia) или situs inversus totalis. [7], When heart transplantation is required in a person with situs inversus, reconstruction of the venous pathways to accommodate a normal donor heart is a major, but not insurmountable, challenge. This presents a surgical challenge to the surgeons operating on the right sided cardiac structures in a case of dextrocardia with situs solitus.[5]. The intestines and other internal structures are also reversed from the normal, and the blood vessels, nerves, and lymphatics are also transposed. However, the orientation of these vessels in a person with situs inversus is reversed, necessitating steps so that the blood vessels join properly. For all visceral organs to be mirrored, the correct term is dextrocardia situs inversus totalis. [citation needed], ECG leads must be placed in reversed positions on a person with dextrocardia. LITFL ECG library is a free educational resource covering over 100 ECG topics relevant to Emergency Medicine and Critical Care. There are two major types of dextrocardia. In this type of dextrocardia… For example, a person with situs inversus who requires a heart transplant needs all their great vessels reattached to the donor heart. Additionally, the position of the heart chambers as well as the visceral organs such as the liver and spleen is reversed (situs inversus). Wearing a medical identification tag can help inform health care providers in the event the person is unable to communicate. In this condition, the tip of the heart (apex) is positioned on the right side of the chest. In this form of dextrocardia, the heart is simply placed further right in the thorax than is normal.

What is dextrocardia situs inversus and how it is different from dextrocardia of embryonic arrest? There are two main types of dextrocardia: dextrocardia of embryonic arrest (also known as isolated dextrocardia) [citation needed] and dextrocardia situs inversus. Medical diagnosis of the two forms of congenital dextrocardia can be made by ECG[2] or imaging. V1: como a posição normal. Called also urethrocystoscopy . [4], In contrast to dextrocardia situ inversus which is only rarely associated with congenital heart disease, dextrocardia situs solitus is often associated with intracardiac anomalies. [6] That is, instead of upper right and lower left, pads should be placed upper left and lower right. Technical dextrocardia refers to an ECG reading that has no basis in the patient's anatomy. The condition may also be discovered during the administration of certain medicines or during tests such as a barium meal or enema. Dextrocardia with Situs Inversus is a rare heart condition characterized by abnormal positioning of the heart. Usually, this would show as an extreme axis deviation. V4R: no quinto espaço intercostal direito, na linha hemiclavicular direita. 2010 May-Jun; 58(3): 241–242. Dextrocardia is further divided into two types: dextrocardia of embryonic arrest, and dextrocardia with situs inversus. 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. As a student,…” Congenital heart defects are present in about 5-10% of affected people. The aortic arch, left ventricle, and cardiac apex are all on the right side.
