In the conference room, only Wu Ting's voice could be heard:
"...The aortic valve is one of the four valves of the heart, located between the left ventricle and the aorta. The aorta is a large blood vessel that supplies the body with oxygenated blood. When the heart beats, the left ventricle contracts, pushing blood through the three sensitive cusps that make up the aortic valve. When the left ventricle relaxes, the aortic valve closes to prevent blood from flowing back into the left ventricle... So, you can think of the aortic valve as a one-way valve!"
"As people age, the aortic valve can become calcified or lose its flexibility due to disease. This makes it difficult for the valve to open, causing the valve opening to narrow. Blood flow is obstructed, which reduces the amount of blood pumped into the aorta and distributed to the rest of the body... This is the complete pathogenesis for this patient..."
