Kalp Kapak Komissürlerinin ve Annuluslarının Sistematik Adlandırılması

Abstract

Background: Several nomenclatures have been defined for easier understanding of cardiovascular anatomical structures. The “Erin commissure and annulus nomenclature” we have developed, aims to name the commissures and annulus of the valves in a certain order. Methods: We renamed the commissures and parts of annulus in a clockwise fashion. We named the commissure, closest to the first surgeon as C1 in all heart valves. Latter commissures are named as C2 and C3 in clockwise fashion. In our naming system, the commissures in aortic, pulmonary and tricuspid valves are named as C1, C2 and C3 and the commissures in mitral valve are named as C1 and C2. We divide the annulus into zones. Each zone is the part of the annulus between two commisures. Zones are named clockwise with reference to C1 commissure as the starting point. These zones are defined as Z1, Z2 and Z3 in aortic, pulmonary and tricuspid valves and Z1 and Z2 in mitral valve. Results: All of the heart valvular commisures and parts of the annulus even the congenital valves are named. Conclusion: The new nomenclature will facilitate learning of topographic anatomy in surgical training.It will provide technical convenience in communication during valve surgery.
