Introduction:
Cardiogenic shock (CS) is a life-threatening condition associated with significant morbidity and mortality. The Impella (Abiomed Inc.) is an axial flow pump on a pigtail catheter that is placed across the aortic valve to unload the left ventricle by delivering non-pulsatile blood flow to the ascending aorta. It is used for high-risk percutaneous coronary intervention and CS.
Areas Covered:
Percutaneous mechanical support devices are placed in a minimally invasive manner and provide life-saving assistance. We review Impella and other percutaneous devices such as intra-aortic balloon pump, TandemHeart, and extracorporeal membrane oxygenation (ECMO) and the evidence supporting their use in the setting of CS.
Expert Commentary:
Impella has been proven to be safe and may be superior to other mechanical support devices in CS.

Shock Waves
When the source's speed approaches the speed of sound, constructive interference between successive wavefronts emitted by the source occurs immediately behind it. Initially, scientists believed that this constructive interference would result in such high...

Blood Pressure: Hypertension and Hypotension
Normal blood pressure is 120/80 mm Hg. Elevated blood pressure is 120-129/under 80 mm Hg. Hypertension, warranting treatment at 130/80 mm Hg, is often asymptomatic and can lead to severe cardiovascular events, aneurysms, peripheral arterial disease, chronic renal disease, or cardiac...
