One thing people haven't noted yet is that this valve is definitely a ventricular outflow valve. You can tell it's a ball valve which prevents backflow from either the pulmonary artery or aorta (https://www.researchgate.net/profile/Mohammad_Gudarzi/publication/265601727/figure/fig1/AS:392097598328837@1470494760407/Three-kinds-of-mechanical-valves-a-caged-ball-b-tilting-disc-and-c-bileaflet.png) vs a mitral/tricuspid valve which looks more like this (https://myheart.net/wp-content/uploads/2015/11/replacement-mitral-valves.jpg)
