A 71-year-old man with early-stage esophageal cancer underwent off-pump coronary artery bypass grafting (CABG) through left thoracotomy to avoid sternotomy to allow subsequent esophageal surgery. The patient had severe double vessel coronary artery disease (the left anterior descending artery and the right coronary artery). Esophageal pull-out resection and reconstruction with the transverse colon over the sternum were planned after recovery from CABG. Therefore, we performed off-pump CABG via left thoracotomy using a saphenous vein Y-graft. Proximal anastomosis was placed in the descending aorta, and the distal anastomoses were completed with a stabilizer and an apical retraction device. Postoperative angiograms showed both grafts were patent and had suitable layout for subsequent esophageal surgery. In conclusion, off-pump CABG via left thoracotomy is an appropriate option for myocardial revascularization, if median sternotomy is contraindicated.

A 2-month-old boy developed Methicillin-resistant <i>Staphylococcus aureus</i> (MRSA) mediastinitis after bidirectional Glenn anastomosis for hypoplastic left heart syndrome. After reexploration, only the skin was closed but the sternum left open, and continuous mediastinal irrigation using saline containing isodine was commenced at an infusion rate of 20-40ml/h. The sternum was closed on day 7 and irrigation was stopped on day 21. The patient was weaned from the ventilator 4 days later, and is currently in a good condition awaiting a Fontan operation.

Between February 1999 and November 1999, 33 patients (age 67.0±7.6 years old) underwent off-pump CABG using coronary shunt tubes. The number of graft anastomoses per patient was 2.8±0.8. The operative mortality was 0%. There was no incidence of on-pump conversion, low cardiac output syndrome, IABP insertion, mediastinitis or stroke. The maximum CPK-MB during the perioperative period was 25.9±18.8IU/<i>l</i>. One patient had perioperative myocardial infarction probably due to native coronary artery spasm. In patients with off-pump CABG, the intubation time, the ICU stay and the hospital stay were shorter. The number of patients who were extubated in the operating room was higher and the cost was lower than those with on-pump CABG. An early phase study revealed patency ratios of 85% (the previous term) and 97% (the latter term). Off-pump CABG is a safe and effective means of revascularization with no mortality, minimal morbidity and good short-term patency.
