Type of disease: Rare conditions
Isolated levocardia is a type of situs inversus where the heart is located in the normal position, but there is a mirror-image reversal of other internal organs. Isolated levocardia may occur alone or with heart defects, heart rhythm abnormalities (sick sinus syndrome or atrioventricular node disorder), spleen defects (absent, underdeveloped, or extra spleen), and intestinal malrotation. Long term outlook varies depending on the presence/absence of associated abnormalities, particularly heart defects. The cause of isolated levocardia is not known. It is not usually associated with chromosome abnormalities.
