What is myocardial protection system?
What is myocardial protection system?
1 Introduction. Myocardial protection during cardiac surgery aims to preserve myocardial function while providing a bloodless and motionless operating field to make surgery easier.
Which is the best method of myocardial protection in open heart surgery?
Warm blood cardioplegia is an effective preservation strategy which is used by some surgeons. An alternative approach to myocardial preservation during CABG surgery, which does not require the use of cardioplegia, is hypothermic intermittent cross-clamp fibrillation, a technique which is still used by some surgeons.
What is cardioplegia solution?
Cardioplegia Solution A is a sterile, non-pyrogenic solution for cardiac perfusion in a Viaflex bag. It is used to induce cardiac stasis and to protect the myocardium during open-heart surgery.
What is antegrade cardioplegia?
Antegrade cannulae are designed to deliver cardioplegia solution to the heart via the coronary ostia in the normal direction of blood flow (antegrade perfusion). Medtronic offers both aortic root cannulae and coronary ostial cannulae.
How many years does it take to be a perfusionist?
To become a perfusionist, it will typically take you a minimum of four to six years. The amount of time it takes to become a perfusionist varies depending on the type of educational program you enroll in. Perfusionist programs are offered at the certificate, bachelor’s and master’s degree level.
Why potassium is used in cardioplegia?
The potassium in the cardioplegic solution serves to stop the heart rapidly before its metabolic stores are depleted, while hypo- thermia reduces the energy requirements of the heart during anoxia [2].
Why does cardioplegia stop the heart?
Cardioplegia is an essential component of cardiopulmonary bypass and with the primary goal to reduce myocardial oxygen demand by creating electrical quiescence and cooling the heart to reduce the ischemic effects of being on bypass.
What is the role of K+ in cardioplegia?
Chemically, the high potassium concentration present in most cardioplegic solutions decreases the membrane resting potential of cardiac cells. The normal resting potential of ventricular myocytes is about -90 mV.
What is cardioplegia used for?
How much money does a perfusionist make?
Cardiovascular perfusionists can obtain starting salaries of $90,000 or more and advance to an average annual salary of $90,000 to $125,000, depending on where they practice.
