[A case of successful emergency coronary artery bypass grafting surgery for failed coronary angioplasty using percutaneous cardiopulmonary support].

This is the first Japanese case of the successful emergency coronary artery bypass grafting (CABG) surgery for failed percutaneous transluminal coronary angioplasty (PTCA) using percutaneous cardiopulmonary support (PCPS). A 81-year-old woman with old myocardial infarction and angina pectoris is presented. Her coronary angiogram showed the 90% and 50% stenosis of the right coronary artery (RCA) and the total occlusion of the left anterior descending artery (LAD). PTCA for the 90% stenosis of RCA was performed. But, during the balloon dilation, her heart rate and blood pressure decreased. PTCA was stopped. As her chest pain was worse, re-PTCA was tried, using PCPS. Under PCPS (3 l/min), the balloon dilation was performed safely and smoothly. But, the unexpected dissection of RCA occurred, and became larger rapidly. After 85 minutes, the emergency CABG was performed. By using PCPS, the stable hemodynamics was given till the operation. CABG to RCA and LAD was performed safely. After the surgery, the patient progressed well. PCPS was a very useful cardiopulmonary assist device.
