Figure 3 (A) Pulsed-wave Doppler recording of mitral inflow velocities with simultaneous respirometer recording in a 64-year-old man with constrictive pericarditis before pericardiectomy. Average early (E) velocity with inspiration was 0.95 m/s and increased to 1.20 m/s with expiration (26% change). (B) After pericardiectomy, late postoperative Doppler echocardiography showed normal diastolic filling pattern (E/A [late] = 1.3; DT = 205 ms). Average E velocity with inspiration was 0.80 m/s and 0.85 m/s with expiration. DT, deceleration time; Exp, expiration; Insp, inspiration.

Figure 4 (A) Pulsed-wave Doppler recording of mitral inflow velocities with simultaneous respirometer recording in a 48-year-old man with constrictive pericarditis before pericardiectomy. Average early (E) velocity with inspiration was 0.75 m/s and increased to 1.0 m/s with expiration (33% change). (B) After pericardiectomy, late postoperative Doppler echocardiography showed restrictive diastolic filling pattern (E/A [late] = 2.6; DT = 130 ms) with no change in E velocity with respiration. DT = deceleration time; Exp = expiration; Insp = inspiration.
