[On-pump coronary artery bypass grafting is still useful for the complete revascularization of low risk patients]

Area of Science:

• Cardiovascular Surgery
• Surgical Outcomes
• Grafting Techniques

Context:

• Complete revascularization using total arterial grafts is associated with superior late surgical outcomes in coronary artery bypass grafting (CABG).
• Off-pump CABG demonstrates advantages in morbidity and mortality compared to on-pump CABG (ONCABG).
• Challenges exist in achieving complete revascularization for multi-vessel disease using off-pump techniques, potentially necessitating cardiopulmonary bypass (CPB).

Purpose:

• To evaluate the optimal surgical strategy for coronary revascularization, balancing completeness of revascularization with the risks associated with cardiopulmonary bypass.
• To identify patient subgroups who may benefit from either on-pump or off-pump CABG, considering surgical complexity and patient risk factors.

Summary:

• Complete arterial grafting yields the best long-term surgical results in CABG.
• While off-pump CABG is generally superior, on-pump CABG may be considered for low-risk patients requiring extensive posterior wall revascularization.
• Acute conversion from off-pump to on-pump procedures increases complication rates and mortality, underscoring the importance of pre-operative planning.

Impact:

• This analysis aids surgeons in selecting the most appropriate CABG strategy, potentially improving patient outcomes and reducing perioperative complications.
• Highlights the trade-offs between complete revascularization and the risks of cardiopulmonary bypass in different patient populations.
• Informs clinical decision-making regarding the use of on-pump versus off-pump CABG for complex coronary artery disease.
