 Cardiac pump - Wikipedia, the free encyclopedia
Cardiac pumps are most often used in heart surgery, so that a patient's heart can be disconnected from the body for longer than the twenty minutes or so it takes a prepared patient to die.
Chronic use of cardiac pumps is contraindicated because the pressure profile of most practical pumps is believed to cause circulatory damage to the brain, especially in extended use.
In France, emergency medical teams (SAMU) use a different kind of portable cardiac pump which stimulates blood circulation by suction.

 New technique to relieve pain after heart surgery
Cardiac patients at the Northwestern Cardiovascular Institute are among the first in the country to benefit from a pump dispense system used to treat pain specifically after heart surgery.
The pain relief pump helps patients to avoid the incapacitating side effects of narcotics that can delay surgical recovery, which means less pain and narcotics use, shorter hospital stays, and a quicker recovery for patients.
While it is a new advancement to use the pain relief pump to treat pain after cardiac surgery, Northwestern Memorial also uses pain relief pumps to treat postoperative pain in a handful of other surgeries, including Bariatric surgery, plastic surgery and some spine surgeries.

 Investor's Business Daily: Breaking News
On-pump cardiac surgery is conducted with the use of a cardiac pulmonary bypass machine, a device that pumps the patient's blood while the heart is stopped and the surgery is performed.
Cardiac surgery, commonly referred to as "open heart surgery," is performed to treat ischemic heart disease or to repair parts of the heart, either on-pump or off-pump.
For off-pump cardiac surgery, physicians slow the heartbeat, stabilize the heart by keeping certain areas immobile with various devices, and perform the surgery without the use of a bypass machine.

 Off-Pump Bypass Surgery - Enloe Medical Center
Off pump bypass surgery, also called beating heart bypass surgery, is a surgical process for the treatment of coronary artery disease (CAD) that eliminates the need for patients to be on a heart bypass, or heart-lung, machine.
The difference is that a small 2- to 3-inch incision is made on the left side of the patient's chest.
There were no deaths at Enloe Medical Center in 2003 related to off-pump bypass surgery patients, when adjusted for risk, according to the latest study by the Society for Thoracic Surgeons.

Severe cardiac failure in chronic dilated cardiomyopathy, resuscitation, acute myocarditis, and Ebstein´s anomaly are reasons for implantation of HeartMate ventricular assist device in adolescent and pediatric patients.
Such therapy allows rehabilitation of patients before elective cardiac transplantation (by removing contraindications to transplantation mainly represented by organ impairment) or acting as a bridge to recovery of the native left ventricular function (depending on underlying cardiac disease).
The implantation of a mechanical circulatory device for end-stage ventricular failure is a possible therapeutic approach in adult and pediatric cardiac surgery and cardiology.

 Cardiology in Critical Care-IABP
Intra-aortic balloon pump therapy helps restore the balance between the supply of oxygen-rich blood the heart receives from the coronary arteries, and the amount of oxygen the heart needs to pump.
During the work phase, your heart pumps oxygen-rich blood into the aorta and out to the far reaches of your body.

 Ion pumps as targets for therapeutic intervention
The clinical success of these drugs continues to make ion pumps desirable as targets for developing new therapeutics including antiulcer and antifungal drugs.
However, it is becoming clear that there is sufficient diversity between the various ion pumps to provide a selective window of interaction leading to safer and more effective therapeutics.
This brief review will focus on essential properties of P-type ion pumps that make them successful targets for existing therapeutics, and will discuss how these properties are being exploited for the development of new classes of therapeutics directed against pathogenic fungi.

 Artificial heart - Wikipedia, the free encyclopedia
This synthetic replacement for an organic mammalian heart (usually human), remains one of the long-sought Holy Grails of modern medicine.
It is distinct from a cardiac pump, which is an external device used to provide the functions of both the heart and the lungs.
An artificial heart is a prosthetic device that is implanted into the body to replace the original biological heart.

 ASHP: Amiodarone Shown to Prevent Atrial Fibrillation in Off-pump Cardiac Surgery Patients
ATLANTA, GA -- December 12, 2002 -- Administering amiodarone after off-pump cardiac surgery may reduce the incidence of postoperative atrial fibrillation, thereby potentially avoiding some of the safety risks that arise when bypass pumps are used.
He cautioned, however, that more research and a larger population is needed to evaluate the general effectiveness of amiodarone in off-pump cardiac surgery patients.
