I believe you are correct with regard to comparison of the aortic valve to the pulmonary and tricuspid valves, which are on the right (lower pressure) side of the heart. My understanding is that defects and leakage in these valves tend to, as you suggest, remain more occult and have to become fairly advanced before really being noticed. The mitral, however, IS on the high pressure (left) side of the heart, and has to deal with the same pressures that the aortic valve does, the difference being that the mitral valve has to hold tight against the pressure generated by contraction of the left ventricle where the aortic's job is to let the blood pass freely out of the heart. Different functions, different failure modes, equally catastrophic, and we all end up as part of this happy group of campers on this forum
