Implication

ITA preference in CABG supported by decades of data; leaves open optimal bilateral ITA strategies.

Key Points

To review the historical evolution, surgical challenges, and evidence establishing the internal thoracic artery as a preferred conduit for coronary artery bypass grafting.
Synthesized clinical experience dating back to 1966 alongside angiographic and survival data evaluating the internal thoracic artery against saphenous vein grafts.
Tracked practice trends and the adoption rate of unilateral and bilateral internal thoracic artery grafting in coronary revascularization.
Initial adoption was hindered by concerns over harvest complexity, arterial fragility, vasospasm, and uncertain flow capacity compared to saphenous veins.
Angiographic evidence after a decade demonstrated superior graft patency and subsequent survival advantages for internal thoracic artery grafts over saphenous vein conduits.
Despite evidence, transition to the internal thoracic artery as the primary conduit for the left anterior descending artery spanned decades, with bilateral grafting exceeding 5% in the US.

Structured PICO

Does the internal thoracic artery provide better patency and survival than saphenous vein grafts in patients undergoing coronary artery bypass?

Population

Patients undergoing coronary artery bypass grafting

Intervention

Internal thoracic artery (ITA) conduit

Comparator

Saphenous vein conduit

Outcome

Graft patency and survival

The internal thoracic artery has evolved from an improbable alternative to the standard-of-care conduit for bypassing the left anterior descending artery due to its superior patency and survival benefits.

Hendrick B. Barner (2012) conducted a review in Coronary artery bypass. Internal thoracic artery (ITA) graft vs. Saphenous vein graft was evaluated. The internal thoracic artery has gradually become the conduit of choice for coronary artery bypass over several decades despite initial skepticism, with bilateral use now expanding.
