Excessive surface fibrosis or fat limits effective electrode insertion in patients requiring epicardial pacing. We present chronic performance of a modified transvenous steroid lead used as an epi-intramyocardial electrode in a patient following repair of a univentricular heart after failure of both standard and steroid-eluting epicardial leads. Low implant threshold values remained stable during a 3-year postimplant interval demonstrating an effective and innovative approach to epicardial pacing.
对于需要心外膜起搏的患者，过多的表面纤维化或脂肪会限制有效电极插入。我们展示了一种改良的经静脉类固醇导线在一名单心室心脏修复术后患者中的长期性能，该导线在标准和类固醇洗脱心外膜导线均失败后用作心外膜-心肌内电极。在植入后的3年期间，低植入阈值保持稳定，证明了一种有效的、创新的心外膜起搏方法。
