[Corrected transposition of the great vessels in the adult. Presentation of a case simulating ischemic cardiopathy].

We report the clinical and laboratory findings in a 58 years old woman with corrected transposition of the great arteries (CTGA), who that presented typical angina pectoris. The diagnosis of ischemic heart disease was supported by the history of a previous myocardial infarction. Other findings were a systolic murmur of mild mitral regurgitation, left bundle branch block and enlarged left ventricle on the chest X-ray. Cardiac catheterization showed a corrected transposition of the great arteries (L-malposition with situs solitus); left and right coronary arteries were free of luminal stenosis. We suggest therefore that anginal chest pain may be due to myocardial ischemia induced by discrepancy between myocardial oxygen consumption and coronary blood flow. This complication may occur in patients with corrected transposition of great arteries surviving in adulthood.
