Completeness of revascularization in multivessel coronary artery disease

Multivessel coronary artery disease (CAD) is frequently encountered in clinical practice among patients with both stable and unstable presentations (1). The question of whether such patients should undergo complete (CR) versus incomplete (IR) revascularization continues to be debated (1-3). This issue was originally recognized and described among patients undergoing coronary artery bypass graft (CABG) surgery, where it was observed that CR conferred both a survival and symptomatic benefit in comparison to IR (3), with CR consequently achieving the stature of a surgical mantra and accepted as a truism (4).
