A case report of myocardial ischemia improvement despite early bypass graft occlusion: Efficiency of physiological reassessment.

ABSTRACT: Patients with functional ischemia often do not complain of chest symptoms even in early occlusion after coronary artery bypass grafting (CABG). The clinical evidence indicating the necessity of revascularization for these patients is unclear. A 70-year-old man who underwent 3 stent implant procedures to treat repeated in-stent restenosis to the left anterior descending artery (LAD) felt effort-related chest pain. Coronary angiography revealed that the patient's jailed diagonal had severe stenosis with delay and the LAD had intermediate stenosis. The instantaneous wave-free ratio (iFR) value of the LAD equalled 0.75. The patient underwent sequential CABG, where the left internal mammary artery (LIMA) to the LAD and diagonal artery grafts were performed. Although his effort-related chest pai
