Table 4. Practical Echocardiographic Approach to Diastolic Function in Intraoperative TEE.

Septal E’ < 7, Lateral E’ < 10 or Vp < 40 cm/s
Grade I (Impaired Relaxation)	Grade II (Pseudo-normal)	Grade III (Restrictive pattern)
E/A < 0.8	E/A 0.8–2.0	E/A ≥ 2.0
DT > 200 ms	DT 160–200 ms	DT < 160 ms
Average E/E’ ≤ 8	Average E/E’ 9–13	Average E/E’ ≥ 14
Ar-Adur < 0 m/s, S/D > 1	Ar-Adur ≥ 30 m/s, S/D < 1	Ar-Adur ≥ 30 m/s, S/D < 1
Valsalva ΔE/A < 0.5	Valsalva ΔE/A ≥ 0.5	Valsalva ΔE/A ≥ 0.5

TEE: transesophageal echocardiography, Vp: propagation velocity, DT: deceleration time, Ar: pulmonary venous A-wave reversal wave, Adur: transmitral A-wave duration.
