Myocardial Protection With Multiport Antegrade Cold Blood Cardioplegia

Cold blood cardioplegia was used for myocardial protection and just before the removal of the aortic cross-clamp, warm blood shot (normo-kalemic) was started through multi-perfusion set attached to cardioplegia cannula in the aortic root and vein grafts.As contraction of heart started the multiport limb attached to cardioplegia cannula was off and cross clamp was removed .The warm perfusion through the vein grafts was continued at controlled pressures of about 50-70 mmHg, flow rate of 10-30ml/min/graft and temperature of 35-37 oC

only cold blood cardioplegia was used for myocardial protection without hotshot.
