Miniseries 2-Septal and paraseptal accessory pathways-Part I: The anatomic basis for the understanding of para-Hisian accessory atrioventricular pathways

Robert H. Anderson et al.

Summary: This study aimed to clarify the anatomical arrangement of the atrioventricular conduction axis, particularly in the regions surrounding its transition from the atrioventricular node to the bundle of His. The para-Hisian areas, which include the fibrofatty tissues of the inferior pyramidal space and the superior atrioventricular groove, were found to be adjacent to this transition. The findings provide a basis for further research on para-Hisian arrhythmias.

Incidence, Predictors, and Implications of Permanent Pacemaker Requirement After Transcatheter Aortic Valve Replacement

Yasser Sammour et al.

Summary: Transcatheter aortic valve replacement (TAVR) is a safe alternative to surgery for patients with severe aortic stenosis, but conduction abnormalities requiring permanent pacemaker (PPM) implantation after the procedure are common and need to be carefully monitored. Research suggests that pre-existing conduction abnormalities may increase the risk of PPM implantation and mortality after TAVR.

Three-dimensional visualization of the bovine cardiac conduction system and surrounding structures compared to the arrangements in the human heart

Marcos C. De Almeida et al.

Summary: This study compares the atrioventricular conduction axis between human and bovine hearts, highlighting significant differences in their cardiac structures. The findings reveal distinct variations in the location and composition of the conduction axis in these two species, providing new insights for anatomical research.

Contrast-enhanced image-guided lead deployment for left bundle branch pacing

Xi Liu et al.

Summary: Using a visualization technique significantly shortens the procedural and fluoroscopic durations of LBBP implantation, leading to fewer lead repositioning attempts.

Similarities and differences in the arrangement of the atrioventricular conduction axis in the canine compared to the human heart

Marcos C. de Almeida et al.

Summary: This study revealed a significant difference in the atrioventricular conduction axis and adjacent structures between canine and human hearts. Canine hearts lacked an inferoseptal recess, while some human hearts also exhibited a similar anatomical arrangement. On the other hand, human hearts with an inferoseptal recess have a relatively shorter nonbranching bundle embedded within the fibrous tissue forming its right wall.
