Key result
Review confirms classic conduction tissue definitions, finding no specialized conducting tissues in pulmonary venous sleeves.
Why the study?
Controversies continue regarding the anatomy of cardiac conduction tissues, most of which could have been avoided with greater attention to original descriptions.
This historical and anatomical review clarifies the structure of the heart's conduction system, noting the absence of specialized conducting tissues in the pulmonary venous sleeves.

Upholds validated conduction anatomy for mapping and ablation; confirms early definitions while leaving open pulmonary vein AF substrates.
Sánchez‐Quintana et al. (2021) conducted a review in Cardiac conduction system anatomy. A review of cardiac conduction tissue anatomy confirms that robust definitions from the early 20th century remain valid, with no special conducting tissues found in pulmonary venous sleeves.
