Implication

May support left thoracotomy for selected redo CABG; leaves open need for comparative trials on long-term outcomes.

Key Points

To evaluate the safety, technical feasibility, and outcomes of a left thoracotomy approach for repeat coronary artery bypass grafting (CABG).
Retrospective review of 20 patients undergoing a second (N=16), third (N=3), or fourth (N=1) CABG via left thoracotomy between 1 and 16 years after initial surgery.
Cardiopulmonary bypass was performed using femoral cannulation with fibrillatory arrest and core cooling (18–33°C) cardioplegia.
Grafting utilized left internal mammary arteries (N=6) and reverse saphenous veins (N=44) with proximal anastomoses to the descending thoracic aorta or left subclavian artery.
Operative mortality included 2 early deaths and 0 late deaths.
Predischarge angiography in 16 patients demonstrated an early graft patency rate of 98% (41/42 grafts).

Structured PICO

Does reoperative CABG through a left thoracotomy result in acceptable mortality and graft patency in patients requiring redo CABG?

Population

20 patients undergoing reoperative coronary artery bypass grafting (CABG) (second CABG in 16, third in 3, fourth in 1) performed 1 to 16 years following the initial procedure, with ejection fraction between 30% and 73%.

Intervention

Reoperative coronary artery bypass grafting (CABG) through a left thoracotomy

Outcome

Early graft patency rate and mortality (early and late deaths)hard clinical

Reoperative CABG through a left thoracotomy is a feasible approach with high early graft patency that may reduce the risk of damage to the heart and existing patent grafts.
