A simplified method for delivery of cold blood cardioplegia and aortic root venting during coronary artery bypass.
We present a simplified method for delivery of cold blood cardioplegia and left ventricular decompression during coronary artery bypass surgery when aortic occlusion is utilized. The system provides immediate delivery of the cardioplegic solution followed by continuous sump suction on the aortic root to decompress the left ventricle and to aspirate non-coronary collateral flow. This system has been utilized in over 200 consecutive cases of coronary revascularization without complication and is a safe, effective and inexpensive method of both delivery of the cardioplegic agent and maintenance of a dry quiet operative field.
