Pulmonary valve: contradictions in terminology and anatomy
https://doi.org/10.15372/SSMJ20200605
Abstract
Data on the anatomy of human heart valves is of a great importance for cardiac surgery, X-ray and ultrasound diagnostics, and additive technologies in bioengineering. This review analyzed Russian and English-written papers and presented contradictions of terminology, macroscopic and microscopic structure, topography of the normal pulmonary valve. The article compared such terms as «pulmonary valve» and «pulmonary root», the approaches of different scientific sources for naming the sinuses and leaflets and analyzed constituents of the pulmonary valve complex. Pulmonary root appearedus to be a distinct structure that includes the distal part of right ventricular outlet and proximal part of the pulmonary trunk. Interleaflet triangles and valvular commissures as well as semilunar leaflets and sinuses of Valsalva are thought to be parts of pulmonary valve complex. According to modern concepts, interleaflet triangles and valvular commissures are not the same and should be distinguished. The mouth of the pulmonary root is not surrounded with planar fibrous ring which anybody could reveal by dissection or histology technics, so the “fibrous ring” of the pulmonary artery is nothing more than an anatomical myth. The paper cited morphometrical data on the perimeter, valve diameters, sizes of semilunar leaflets and sinuses, revealed various models of regression and correlation between the size of the valve and body parameters. We summarized data on cell and fiber architectonics of the valve. Terminological and morphometric consensus in heart valves anatomy is the mandatory step on the way to the evidence-based morphology.
