ClinConnect Summary

The enrolled patient underwent routine sternotomy, and left internal thoracic artery (LITA) and saphenous vein (SV) are harvested. After harvest, the patient is randomized to Y-composite group or aortocoronary group.

For Y-composite group, SV is anastomosed to LITA as Y-composite fashion. Then, LITA is anastomosed to left anterior descending artery. SV is anastomosed to the rest of the target vessels with sequential anastomosis technique (e.g. diagonal branch, obtuse marginal branch, posterolateral branch and posteriori descending artery).

For aortocoronary group, LITA is anastomosed to l...

Eligibility criteria

• Inclusion Criteria:
• • A patient who is going to receive coronary artery bypass grafting
• • Older than 19 years
• • Coronary artery bypass grafting is going to be performed with left internal thoracic artery and saphenous vein graft
• Exclusion Criteria:
• • Other concomitant procedures (e.g. valve or aorta surgery) is planned
• • Patients with severe comorbidities which limit the life expectancy of them below 1 year (e.g. terminal cancer)
• • Patients whose left internal thoracic artery or saphenous vein is not available due to the low quality, severe injury, or absence of the graft
