“Integrated myocardial protection” is a myocardial protection strategy that includes antegrade and retrograde delivery of cold-blood cardioplegia and warm cardioplegia perfusion for induction and resuscitation.

Hypothermia reduces myocardial oxygen demand and ischemic injury when coronary flow is interrupted; however. Myocardial protection during cardiac operations: decreased morbidity and lower cost with blood cardioplegia and coronary sinus perfusion.

Circulation ; 54 (2): – Melrose, DG, Dreyer, B, Bentall, HH, et al. Elective cardiac arrest. Myocardial Protection Myocardial protection during cardiac surgery has evolved over the years, and the concept of chemical cardioplegia was introduced in Before the popular use of chemical cardioplegia, topical cardiac hypothermia was used.

On the other hand, crystalloid cardioplegia is affordable and simple to deliver, and a single application suffices for adequate arrest.

Myocardial membrane potential at the 4 phases of the cardiac cycle. When extracellular cardioplegia with high K + (20 mmol/l) displaces blood surrounding the myocytes, the cell membrane potential is increased and it depolarizes more readily, i.e.

at a less negative membrane potential. Objective: Myocardial protection with blood cardioplegia during cardiac surgery is increasingly preferred, but few studies have compared the protective effects of crystalloid cardioplegia.

Cardioplegia Temperature The composition of cardioplegia solutions varies considerably; in contrast, myocardial temperature during cardioplegia is almost uniformly reduced to between 10°C and 12°C or less by the infusion of refrigerated cardioplegia and.

These axioms form the foundation for most cardioplegic solutions today. However warm cardioplegia was successfully introduced in by Calafiore and colleagues.

It seems to offer equivalent myocardial protection under the critical condition that the solution must be applied repetitively or continuously to avoid oxygen deficit of the heart. The convenience of most cardioplegic solutions lies in the good myocardial protection—even Author: Alexandro Hoyer, Philipp Kiefer, Michael Borger.

Cardioplegia is an essential component in myocardial protection during aortic cross-clamping and cardiopulmonary bypass. A good understand of the various compositions of cardioplegia, routes of administration, and potential side effects are necessary to reduce morbidity and mortality in patients undergoing cardiac surgery.

Myocardial protection during cardiac surgery aims to preserve myocardial function while providing a bloodless and motionless operating field to make surgery easier. Myocardial protection, since the original reports of Bigelow [1] has been obtained by decreasing myocardial oxygen demand as a consequence of by: The Quest Myocardial Protection System, consisting of the MPS 2 Console and the MPS 2 Delivery Set used together, is intended for use by perfusionists and physicians to deliver whole blood (from any arterial source) and/or cardioplegia solutions to the heart during open heart surgery up to six hours.

Cardioplegic techniques for myocardial protection involve the delivery of cardioplegic solution to the myocardium to provide diastolic electromechanical arrest. This is administered by an anterograde approach via the aortic root or direct coronary ostium access, or by a retrograde manner if severe coronary artery occlusions exist.

Myocardial protection is regarded as one of the most important, yet also most controversial aspects of cardiac surgery. There has been considerable improvement in myocardial protection strategies over recent years, utilising a variety of new approaches to treat cardiac diseases, and this text is intended to embrace the state of the art in this field.

The primary method of myocardial protection during cardiopulmonary bypass (CPB) remains the administration of cardioplegia and the institution of hypothermia. CARDIOPLEGIA Cardioplegia solution composition varies between institutions but is generally composed of a combination of the following.

Custodiol cardioplegia is attractive for minimally invasive cardiac surgery, as a single dose provides a long period of myocardial protection.

Despite widespread use in Europe, there is little data confirming its efficacy compared with Cited by: Myocardial protection is regarded as one of the most important, yet also most controversial aspects of cardiac surgery. There has been considerable improvement in myocardial protection strategies over recent years, utilising a variety of new approaches to treat cardiac diseases, and this text is intended to embrace the state of the art in this book summarises the state.

In the early s, Matte and del Nido 4 developed a novel cardioplegia solution for myocardial protection at the University of Pittsburgh.

The upper line reports concepts of myocardial protection, and the lower line reports technologic advances in the delivery of myocardial protection. Dual-withdrawal delivery refers to the technique of diluting crystalloid cardioplegia solution with blood from the venous reservoir.

However, blood cardioplegia produces good myocardial protection, suggesting that the concerns over viscosity and capillary sludging are overstated.

The ideal hematocrit for blood cardioplegia is unknown, but it may depend on the temperature of the myocardium and the frequency of administration. Myocardial protection: the rebirth of potassium-based cardioplegia.

The UCLA School of Medicine, University of California, Los Angeles, by: Custodiol cardioplegia is attractive for minimally invasive cardiac surgery, as a single dose provides a long period of myocardial protection. Despite widespread use in Europe, there is little data confirming its efficacy compared with conventional.

However, our results in this study confirmed the results of the large meta-analysis study of Guru and coworkers, and showed that there was less cardiac enzymes release after the application of warm blood cardioplegia for myocardial protection in patients undergoing CABG as compared to cold crystalloid cardioplegia.

That indicates less Cited by: 2. Download Citation | Myocardial Protection in Children | The combination of hypothermia and potassium-based cardioplegic arrest has become the most common method of myocardial protection in the.

Our approach provides adequate myocardial protection, minimal disruption of surgery and excellent long-term by: The most consistent component of myocardial protection strategies until the more recent introduction of warm cardioplegia (see later section) has been myocardial cooling or hypothermia.

The direct correlation between lowering heart temperature and lowering oxygen requirements of the heart is well recognized (Fig. ).
