A method and apparatus for treating an acute myocardial infarction is provided. The apparatus comprises an ultrasound catheter that can be inserted into the esophagus to deliver ultrasound energy to the heart and coronary vasculature. The ultrasound energy can enhance the effect of an intravenously administered thrombolytic drug on a blood clot within the coronary vasculature. The ultrasound catheter can have a means for promoting acoustic coupling with the esophagus and a means for preventing or reducing aspiration of fluids into the lungs.
