我们已对猪心肌进行了五次胸腔镜起搏器导线植入。通过胸腔镜在左心室顶端上方的心包上切开一个直径约2厘米的小开口，避免损伤膈神经。通过套管针引入三个旋入式或两个刺入式标准无缝线单极心外膜电极，然后旋入或刺入左心室心尖附近的心肌，避开冠状血管。手术过程中出血和心律失常可以忽略不计。植入导联后起搏阈值和导联阻抗的电气测试显示每根导联的值都可接受。我们的结论是，胸腔镜植入起搏器导线是可行的，并且当传统的经静脉技术不可用或有禁忌时，可以用作微创选择。
We have performed five thoracoscopic pacemaker lead implantations into the porcine myocardium. A small opening, approximately 2 cm in diameter, was made thoracoscopically in the pericardium overlying the apex of the left ventricle, avoiding phrenic nerve injury. Three screw-in type or two stab-in type standard sutureless unipolar epicardial electrodes were introduced through a trocar, and then screwed or stabbed into the myocardium near the apex of the left ventricle, avoiding the coronary vessels. Hemorrhage and arrhythmia were negligible during the procedures. Electrical tests of the pacing threshold and lead impedance after implantation of the leads revealed acceptable values in each lead. We conclude that thoracoscopic implantation of pacemaker leads is feasible, and may be used as a minimally invasive option when conventional transvenous techniques are unavailable or contraindicated.
