Abstract Physiological assessment is challenging in patients with multivessel disease (MVD) with a chronic total occlusion (CTO) and may result in inappropriate treatment decisions. We report herein, for the first time to our knowledge, on the dynamic changes of the instantaneous wave-free ratio in the CTO collateral donor artery before and after coronary artery bypass grafting (CABG). Our case highlights the paramount importance of collateral circulation when interpreting invasive indices of coronary stenosis severity to guide decision-making for CABG in MVD patients with a CTO. This may be particularly relevant to reduce the risk of early graft failure in patients with MVD undergoing CABG.

Transit Time Flowmetry

Intraoperative Transit Time Flowmetry is currently recommended to assess graft patency during coronary artery bypass grafting (CABG), especially in presence of haemodynamic instability or inability to wean the patient from cardiopulmonary bypass, new regional wall motion abnormalities, or significant ventricular arrhythmias. The VeriQ™ system is one of the currently available systems, which detects imperfections that may be corrected by graft revision. In this case report, multivessel coronary spasm (CS) post-CABG interferes with these intraoperative parameters misleading initially into false results. Cardiac surgeons should bear in mind the limit of VeriQ in distinguishing between graft failure and CS. Angiography may be considered in patients with decreased graft flow despite revision of anastomosis and vasodilatory treatment for the definitive diagnosis.
