The Impella - minimally invasive, catheter-based cardiac assist device

The Impella is a minimally invasive, catheter-based cardiac assist device designed to directly unload the left ventricle, reduce myocardial workload and oxygen consumption, and increase cardiac output and coronary and end-organ perfusion.

The Impella can be inserted into the left ventricle in a Cath Lab via a standard guidewire through the femoral artery, into the ascending aorta, across the valve and into the left ventricle.The tip of the catheter contains a “pigtail” that crosses the patient’s heart valve and rests in the left ventricle, generating flows up to 2.5 L/min. The Impella is hemocompatible, does no compromise to valve function. There is low hemolysis, bleeding, and stroke rates.

Q: Lab call you with result that patient's pleural fluid has cholesterol level more than 45 mg/dL (1.16 mmol/L). What does it mean?


A; Pleural fluid is probably an exudate.

Using a cutoff point of 45 mg/dL for pleural cholesterol and/or LDH over 200 IU/L identified exudates with a sensitivity of 99% and a specificity of 98%.

Q: What is the mechanism of action of Mannitol in control of Intracranial Hypertension (Increase ICP)?


A; Immediately after bolus administration Mannitol expands circulating volume by help of osmotic forces, decreases blood viscosity, resulting in reflex vasoconstriction and lowering of intracranial pressure. Its osmotic properties take effect in 15-30 minutes when it sets up an osmotic gradient and draws water out of neurons.

Q: Does Phenytoin (Dilantin) get cleared by hemodialysis or hemoperfusion?


A; No (clinically insignificant removal)

Clinical significance:

  • In Phenytoin toxicity/overdose, Hemodialysis or hemoperfusion are ineffective for enhancing elimination.
  • Hemodialysis patients do not require extra dosing post dialysis though require frequent monitoring due to lower albumin level.
