The presence of situs inversus in association with dextrocardia is significantly less strongly associated with the presence of congenital heart disease than in patients with dextrocardia and situs solitus. The aortic arch is however commonly right-sided. The more common congenital heart defects when they do occur, include corrected transposition, double outlet right ventricle, pulmonary stenosis, and ventricular septal defect. Pulmonary disorders however are more commonly associated with situs inversus totalis than isolated dextrocardia and include Karthagener's syndrome. This syndrome comprises dextrocardia, visceral situs inversus, chronic bronchiectasis, nasal polyposis, and sinusitis. In males there may be associated infertility.
