Figure 1. Pulse Doppler showing transmitral (A and B) and pulmonary venous (C and D) flow: (A) Mitral inflow pattern E > A in a young, healthy individual; (B) mitral inflow pattern E < A noted in an elderly healthy individual; (C) pulmonary venous flow S < D in a young, healthy individual; and (D) pulmonary venous flow S > D in an elderly, healthy individual. E: Early diastolic transmitral flow velocity; A: late diastolic transmitral flow velocity; S: systolic velocity; D: diastolic velocity.
