Fig. 1From: Pitfalls of anesthetic management with the Impella® 5.0 device: a case seriesa Mid-esophageal long-axis view of transesophageal echocardiography. Yellow arrow indicates Impella cannula and green arrow indicates artifacts.

Red arrow indicates regurgitation jet in the left ventricle due to aortic insufficiency. It was clearly identified without artifacts on this viewBack to article page
