“…The optimal cutoff of ∆LVAT2% (∆LVAT2/LVAT RVSP ) for differentiating LBBP from LVSP was 21.2%, with a sensitivity of 84.0% and a specificity of 100%. Among patients with HF, ∆LVAT1 >9.0 ms and ∆LVAT1% >9.8% have been found to have high accuracy in indicating LBB capture [24]. Vijayaraman et al have also reported that an absolute value of 8 ms for the difference in RWPTs (∆RWPT) during HBP and ns-LBBP/LVSP is highly accurate (sensitivity of 100% and specificity of 93.3%) in confirming LBB capture in patients with LBBB [23].…”

“…Because LBBP captures the distal HB, the fastest activation of the LV lateral wall and the shortest LVAT have been observed with this method [23]. Qian et al have developed a personalized LBB capture criterion based on patients' intrinsic HBP and RVSP electrical parameters during implantation [24]. A total of 105 patients were enrolled: 80 with normal cardiac function and 25 with HF.…”

Left bundle branch pacing (LBBP) emerged as a new physiological pacing strategy during the past several years. Recent observational studies have demonstrated the advantages of LBBP, including a high success rate, stable pacing parameters, and excellent clinical benefits. Widespread adoption of LBBP will depend on improvements in device/lead technology and further verification of its efficacy in large randomized clinical trials. In this review, we summarize recent advancements in LBBP, including the definition and evaluation of left bundle branch capture, LBBP applications, and future directions in this growing field.

“…[ 36 , 37 ] However, when compared with LBB pacing, LVSP has been associated with significantly longer left ventricular activation time in V5-V6 and longer paced QRS durations. [ 33 , 38 ] Consequently, this could potentially lead to a decrease in LV synchrony. [ 39 ] In patients with HF, LBB pacing was associated with a significant reduction in the composite outcome of HF-related hospitalisation and all-cause mortality compared with LVSP (Cox proportional HR: 0.36, 95% CI [0.197–0.654]; p=0.001).…”

Cardiac resynchronisation therapy (CRT) reduces the risk of heart failure-related hospitalisations and all-cause mortality, as well as improving quality of life and functional status in patients with persistent heart failure symptoms despite optimal medical treatment and left bundle branch block. CRT has traditionally been delivered by implanting a lead through the coronary sinus to capture the left ventricular epicardium; however, this approach is associated with significant drawbacks, including a high rate of procedural failure, phrenic nerve stimulation, high pacing thresholds and lead dislodgement. Moreover, a significant proportion of patients fail to derive any significant benefit. Left bundle branch area pacing (LBBAP) has recently emerged as a suitable alternative to traditional CRT. By stimulating the cardiac conduction system physiologically, LBBAP can result in a more homogeneous left ventricular contraction and relaxation, thus having the potential to improve outcomes compared with conventional CRT strategies. In this article, the evidence supporting the use of LBBAP in patients with heart failure is reviewed.
