Figure 5. Impella Catheter Inlet in Aorta (TEE)
• Catheter inlet area in aorta or near the aortic valve
• Catheter pigtail too close to the mitral valve
Figure 6. Impella Catheter in Papillary Muscle (TEE)
• Catheter pigtail in papillary muscle
• Catheter inlet area more than 4 cm below the aortic valve or lodged
between papillary muscle and the myocardial wall
• Catheter outlet area too close to the aortic valve
Four Transthoracic Echocardiographic (TTE) images
Figure 7. Correct Impella Catheter Position (TTE)
• Catheter inlet area 3.5 cm below the aortic valve
• Catheter outlet area well above the aortic valve
• Catheter angled toward the left ventricular apex away from the heart
wall and not curled up or blocking the mitral valve
