Features of patients in which grafts visualization was difficult
| Group | Reason for poor visualization | HR and Rhythm | Type of graft | |
|---|---|---|---|---|
| #1 | TAG | Clip artifact | NSR, HR < 65 | Sequential RIMA to OM and PDA |
| #2 | TAG | Clip and rhythm artifact | NSR, HR < 63 | Sequential RIMA to OM1 and OM2 |
| #3 | TAG | Clip and respiratory artifact | NSR, HR < 74 | Free radial to OM1 |
| #4 | TAG | Clip and rhythm artifact | NSR, HR < 84 | Free radial to PDA |
| #5 | TAG | Clip artifact | NSR, HR < 69 | Sequential graft to OM and LVb |
| #6 | LIMA+SVG | Clip artifact | NSR, HR < 68 | Sequential graft SVG to LVb and PDA |
HR: heart rate; TAG: total arterial grafting; NSR: normal sinus rhythm; RIMA: right internal mammary artery; OM: obtuse marginal branch of the circumflex; PDA: posterior descending artery; LVb: left ventricular branch of the circumflex; SVG: saphenous vein graft.
