Table 2 Hemodynamic in patients with and without post-CPB left ventricular dysfunction

From: Preoperative diastolic function predicts the onset of left ventricular dysfunction following aortic valve replacement in high-risk patients with aortic stenosis

 

No LV dysfunction (n = 56)

With LV dysfunction (n = 38)
