“…Some of the above factors have been proven to be predictors of new conduction block after TAVR, with the prosthesis implantation depth the most relevant risk factor. Other risk factors including the type of valve implanted, overexpansion of native annulus, the occurrence of right bundle branch block (RBBB) at baseline, preexisting LVOT calcification, preexisting first-degree AVB and prolonged baseline QRS duration, previous coronary bypass and female gender [15][16][17]. The presence of RBBB at baseline was one of the important predictors.…”

Transcatheter aortic valve replacement possesses a high validity for patients with aortic stenosis who are considered high risk for aortic valve replacement surgery, nowadays it is also considered for patients with intermediate risk or even lower risk in certain situations. The incidence of new conduction abnormalities remains to be a tough problem, in particular, left bundle branch block. New-onset left bundle branch block is a major concern despite improvements in valve technology, and it may affect postoperative prognosis. Understanding the anatomical relationship between the conduction system and the aortic root, clarify factors related to the procedure, devices, and patients, might help to reduce the conduction abnormalities. Physiological pacing has emerged as a reasonable pacing strategy for patients with cardiac insufficiency post-valve replacement, especially combined with left bundle branch block. The purpose of this review is to summarize the current opinion on the incidence of new-onset left bundle branch block associated with transcatheter aortic valve replacement, to offer insights into its anatomical and procedural causes, clinical consequences, and more importantly, the prospect of applying physiological pacing as a therapeutic method for these patients.

“…Fujita et al (Fujita et al 2016) and Sammour et al (Sammour et al 2021) demonstrated that the cause of conduction block after surgery may be the displacement of calcification, which leads to continuous compression or permanent damage of the atrioventricular conduction system at the junction between the right coronary sinus and the noncoronary sinus. Studies have shown that an excessively low position of the stent increases the incidence of conduction block, especially left bundle branch block (Phan et al 2020). Conduction block usually occurs immediately after the operation or up 24 to 48 hours later and often requires a permanent pacemaker implant (Aymond et al 2021).…”

Transcatheter aortic valve replacement (TAVR) has been performed for nearly 20 years, with reliable safety and efficacy in moderate- to high-risk patients with aortic stenosis or regurgitation, with the advantage of less trauma and better prognosis than traditional open surgery. However, because surgeons have not been able to obtain a full view of the aortic root, 3-dimensional printing has been used to reconstruct the aortic root so that they could clearly and intuitively understand the specific anatomical structure. In addition, the 3D printed model has been used for the in vitro simulation of the planned procedures to predict the potential complications of TAVR, the goal being to provide guidance to reasonably plan the procedure to achieve the best outcome. Postprocedural 3D printing can be used to understand the depth, shape, and distribution of the stent. Cardiovascular 3D printing has achieved remarkable results in TAVR and has a great potential.

“…In the current study, we demonstrated that women have shorter HV intervals before TAVR and HV prolongation is less frequently noted after TAVR. Previous studies identified that women require less often PM after TAVR [ 4 ] and are more likely to recover the conduction disturbances during FU (seen as a reduction in ventricular pacing burden) provided the QRS duration improves and/or the LBBB resolves [ 5 ]. Our findings are hypothesis-generating, warranting further studies assessing the role of sex-specific cut-offs of the HV interval in women undergoing TAVR.…”
