Acute coronary syndrome during pregnancy.

Two cases of myocardial infarction during the second trimester of pregnancy are presented. Both patients were treated with thrombolytic therapy. In the first case the treatment was successful, in the other patient thrombolysis only temporarily relieved the symptoms. Therefore, angiography was performed and a significant stenosis in the left anterior descending coronary artery was successfully treated with balloon angioplasty. Both women delivered a healthy child, the first child was born at term, the second at a gestational age of 33 weeks. Percutaneous intervention versus thrombolytic therapy in pregnancy is discussed.
