Also known as: Portable heart pump
Types of Impella
Impella RP – placed in the right ventricle and extends into the pulmonary vein. It pulls blood from the Inferior Vena Cava (IVC) into the pulmonary artery so that the right heart can be supported and not pump too hard.
Impella – placed in the left ventricle and extends into the aorta. It pulls blood from the left ventricle into the aorta so that the left heart can be supported and not pump too hard.
- In heart failure
- High-risk Percutaneous Coronary Interventions (PCI)
- In cardiogenic shock
Preparing for the procedure:
How it is performed:
- Firstly, a cardiac catheterization is performed to check for any blocks in the coronary arteries. A catheter (a thin, long tube) is placed in either your arms, legs, or groin and is monitored by an x-ray camera until it reaches the coronaries.
- A contrast dye is then infused so that the arteries can be seen.
- The cardiologist will determine the type of impella required.
- Once the Impella is placed, the ventricular functions can be analyzed in real-time through a monitor.
