007268. [edit on Wikidata] A ventricular assist device (VAD) is an electromechanical device that provides support for cardiac pump function, which is used either to partially or to completely replace the function of a failing heart. VADs can be used in patients with acute (sudden onset) or chronic (long standing) heart failure, which can occur ...
Ventricular fibrillation (V-fib or VF) is an abnormal heart rhythm in which the ventricles of the heart quiver. [2] It is due to disorganized electrical activity. [2] Ventricular fibrillation results in cardiac arrest with loss of consciousness and no pulse. [1] This is followed by sudden cardiac death in the absence of treatment. [2]
Heart failure (HF), also known as congestive heart failure (CHF), is a syndrome caused by an impairment in the heart 's ability to fill with and pump blood. Although symptoms vary based on which side of the heart is affected, HF typically presents with shortness of breath, excessive fatigue, and bilateral leg swelling. [ 3 ]
Cardiogenic shock. Cardiogenic shock is a medical emergency resulting from inadequate blood flow to the body's organs due to the dysfunction of the heart. Signs of inadequate blood flow include low urine production (<30 mL/hour), cool arms and legs, and decreased level of consciousness. People may also have a severely low blood pressure and ...
The left atrial appendage is a pouch-like structure located in the upper part of the left atrium. [1] Left atrial appendage occlusion (LAAO) is an alternative therapy to oral anticoagulation in a certain subset of patients with atrial fibrillation. Atrial fibrillation is characterized by an irregular and uncoordinated pumping function of the atria.
During a protected percutaneous coronary intervention (Protected PCI) procedure, "the Impella 2.5 heart pump helps maintain a stable heart function by pumping blood for the heart. This gives a weak heart muscle an opportunity to rest and reduces the heart’s workload, preventing the heart from being overstressed by the procedure as coronary ...
The pumping of blood is considered the workload of the heart and requires power expenditure. Acute cardiac unloading is any maneuver, therapy, or intervention that decreases the power expenditure of the ventricle while maintaining cardiac output. Oxygen consumption (MVO2) is a direct measure of the total energy requirements of the heart ...
Hypovolemic shock is a form of shock caused by severe hypovolemia (insufficient blood volume or extracellular fluid in the body). [1][2] It can be caused by severe dehydration or blood loss. [3][2] Hypovolemic shock is a medical emergency; if left untreated, the insufficient blood flow can cause damage to organs, leading to multiple organ failure.
