2. Fig 1
Graft flow measurement technique. Cardioplegic solution pumped through proximal end of graft at a mean pressure of 100 mg Hg after completion of distal anastomosis. I.D. = inside diameter; W.T. = wall thickness.

Reversal of acidosis with establishment of flow through graft indicates adequate revascularization. CP = cardioplegic solution; LIMA = left internal mammary artery; OMB = obtuse marginal branch; XC = cross-clamp.

4. Fig 3
Technically adequate anastomosis. CP = cardioplegic solution; LAD = left anterior descending coronary artery; LIMA = left internal mammary artery; SVG = saphenous vein graft; top tracing = pH in the posterior LV wall; bottom tracing = pH in the anterior wall.
