Hyperacute anterior myocardial infarction in a patient with dextrocardia and situs inversus

Dextrocardia with situs inversus is an uncommon congenital condition in which the major visceral organs are reversed. The clinical diagnosis and electrocardiographic localization of myocardial infarctions in these patients remain a great challenge unless dextrocardia is recognized. A 50-year-old male with known dextrocardia and situs inversus presented with acute chest pain radiating to the right arm. The reversed normalized electrocardiogram showed acute anterior myocardial infarction and cardiac catheterization showed a proximal occlusion of the left anterior descending artery. He underwent coronary angioplasty with stenting, resulting in relief of chest pain and improvement in his clinical condition.
