Table 4 Comparison of intraoperative TTFM parameters between venous grafts going to the left and to the right territory

From: Influence of coronary territory on flow profiles of saphenous vein grafts

Variable Mean graft flow (ml/min) Pulsatility Index Diastolic filling (%) Backward flow (%) By-pass time (min) Mean arterial pressure at TTFM (mmHg)
