Therefore, the major cellular and molecular events of valve development are largely conserved among animals with hearts composed of multiple chambers.[well established][VHOG] UBERON:0002135 UMLS:C0026264 VHOG:0000817 bicuspid valve galen:MitralValve left atrioventricular valve uberon valva atrioventricularis sinistra valva mitralis outflow part of left atrium mitral valve anulus
