Figure 2 Preoperative and Postoperative Parameters in Patients Undergoing PTE
The p values are significant for all comparisons between preoperative and postoperative parameters except Em (septal). All variables are presented as mean ± standard deviation. Solid bars = postoperative; open bars = preoperative. A = A velocity; CTEPH = chronic thromboembolic pulmonary hypertension; D = diastolic pulmonary venous flow velocity; E = E velocity; Em = early mitral annular tissue Doppler velocity; PTE = pulmonary thromboendarterectomy; S = systolic pulmonary venous flow velocity.
