His bundle pacing (HBP) has been shown to be a good alternative to conventional cardiac resynchronisation therapy (CRT) and may theoretically provide an additional benefit where CRT has a response deficit of at least 30%. HBP requires mapping and identification of the His bundle, and to this purpose the lead delivery is challenging. This first-reported case series from Africa shares early experience with different pacing indications (complete heart block and pre-existing right ventricular pacing; heart failure with left bundle branch block) for using a standard 5.6F, Solia S 60, IS-1, ProMRI bipolar pacing lead and an 8.7F Selectra 3D introducer guide, 32-39-cm working length with 40/55/65-mm proximal radii (Biotronik). These cases highlighted the importance of appropriate programming when implanting HBP and of assessing the conduction system to predict patients who might benefit from HBP and additional left ventricular lead implant. The Biotronik Solia lead and delivery guide were found to be feasible and reliable in these cases. The Biotronik conduction system pacing tools were used with good acute outcomes in patients with different pacing indications.
希氏束起搏(HBP)已被证明是传统心脏再同步治疗(CRT)的良好替代方案,并且理论上在CRT反应不足至少30%的情况下可能提供额外益处。HBP需要对希氏束进行标测和识别,为此,导线递送具有挑战性。这个来自非洲的首次报告的病例系列分享了使用标准的5.6F、索利亚S 60、IS-1、ProMRI双极起搏导线以及8.7F Selectra 3D导入器导向装置(工作长度32 - 39厘米,近端半径40/55/65毫米,百多力公司)用于不同起搏适应症(完全性心脏传导阻滞和既往右心室起搏;左束支传导阻滞所致心力衰竭)的早期经验。这些病例突出了植入HBP时进行适当程控以及评估传导系统以预测可能从HBP和额外左心室导线植入中获益的患者的重要性。在这些病例中,发现百多力索利亚导线和递送导向装置是可行且可靠的。百多力传导系统起搏工具在不同起搏适应症的患者中使用取得了良好的急性效果。
