Abstract
Introduction. The study consists a detail morphometric investigation of the pulmonary valve by autopsy and computed tomography (CT) scan.
Objective. The aim of this study is to disclose new geometric features of pulmonary valve and to discuss how we can use a new knowledge for cardiovascular surgery.
Material and methods. Morphometric measures of pulmonary valve undergone in to two groups: the first one – autopsy, the second one – CT scan.
Results. We received similar results in both groups. The geometry of “healthy” pulmonary valve has gold ratio proportions with strong correlation between two parts of them have been found in both groups for valve diameter (d) and height (h): d/h=(d+h)/d; for cusps: length (l) and height (h): l/h=( l+h)/l. The values of both proportions tended to Fibonacci number (1.618). Two equations for template to make pulmonary valve prosthesis were proposed and patented (h=d/1.618; l=h•1.618).
Conclusion. Morphometric investigation of pulmonary valve could be done by CT scan. The pulmonary valve geometry consists gold ratio proportions. This knowledge could be helpful for surgeons, radiologists and others.
