Brief Summary:
The purpose of this study is to determine if a device known as the TandemHeart® System (TandemHeart) can help limit heart damage and reduce serious complications after a certain type of heart attack (acute ST elevation anterior wall myocardial infarction [STEMI]) by evaluating the use of the TandemHeart system prior to a procedure called percutaneous coronary intervention (PCI)
