1. A medical information processing apparatus comprising:
processing circuitry configured to
obtain medical images taken at a plurality of points in time;
obtain structures of valve leaflets of a heart valve rendered in a medical image taken at a first point in time among the plurality of points in time, the first point in time being a point in time at which the heart valve is in a first state, which is a state in which the heart valve is closed;
obtain the structures of the valve leaflets of the heart valve rendered in a medical image taken at a second point in time among the plurality of points in time, the second point in time being a point in time at which the heart valve is in a second state, which is a state in which the heart valve is open; and
calculate a measurement value related to a contact part between the valve leaflets of the heart valve in the first state, on a basis of: a length related to the structures of the valve leaflets of the heart valve in the first state; and a length related to the structures of the valve leaflets of the heart valve in the second state.
