摘　　要：本研究应用经食管超声心动图及彩色室壁运动分析技术对冠心病多支病变患者在激光心肌血运重建术中进行了小剂量多巴酚丁胺试验（5μg／kg／min），并探讨了经食管超声对判断CO2激光心肌打孔成功的价值。结果表明：1．小剂量多巴酚丁胺试验可以检出冬眠的心肌节段，并对术中寻找合适的打孔部位有重要的临床意义；2．经食管超声可以直观、清晰地判断激光打孔是否成功。当庄室胜或左室流出道内出现微气泡群时，提示打孔成功。本试验通过经食管超声心动图证实有70％的孔道打孔成功。Transesophageal echocardiography (TEE) and color kinests (CK) technique were used to monitor the effects of transmyocardlal CO2 laser revascularization operation applied to 4 severe chronic ischemic heart disease patients.Low dose Dobutamine trial (5 μg/Kg/min) was performed during the operative process, proved to be useful for selecting the hiberating myocardial segment and determining the locality for drilling. TEE monitor ed 70% success drilling rate and verified air bubbles in the left ventricular and outflow tract.
