A 55-year-old man presented to the emergency department with worsening shortness of breath 1 month after a gastrointestinal bleed. He had congestive heart failure, and an electrocardiogram suggested ischemic heart disease involvement. Echocardiography revealed a ventricular septal defect complicated by a left ventricular aneurysm in the inferior-posterior wall. Conservative treatment was started, but hemodynamic collapse occurred on the third day of admission and coronary angiography revealed a revascularizing lesion in the right fourth posterior descending coronary artery. Subsequently, his hemodynamic status continued to deteriorate, even with an Impella CP® heart pump, so ventricular septal defect patch closure and left ventricular aneurysm suture were performed. His condition improved and he was discharged on day 23 of admission and was not readmitted within 6 months after the procedure. Hemodynamic management of ventricular septal defects requires devices that reduce afterload, and clinicians should be aware of the risk of myocardial infarction after gastrointestinal bleeding.
