A 29-year-old primiparous woman had an inferior myocardial infarction at 26 weeks' gestation. Coronary angiography showed subtotal occlusion of the right coronary artery. Percutaneous transluminal angioplasty and intracoronary urokinase infusion failed to relieve the obstruction. Placement of two Gianturco-Roubin flexible stents created adequate coronary perfusion.
