“…[5] In research performed by Wheeldon et al [6] in 1992, the use of retrograde blood cardioplegia was performed in less than 6% of the centers. The continuous retrograde blood microcardioplegia was introduced into our country by Braile et al, proving to be safe and providing adequate myocardial protection in conventional cardiac surgery [7].The aim of this study is to describe the experience of a single center where all patients received the same organ preservation solution and underwent retrograde continuous blood microcardioplegia during implantation of the graft and assessing factors of early and late mortality with the use of this technique. …”

Fatores associados à sobrevida em pacientes submetidos a transplante cardíaco utilizando microcardioplegia sanguínea retrógrada Associated factors with survivals in patients undergoing orthotopic heart transplant using retrograde blood microcardioplegia Abstract Background: Several techniques and cardioplegic solutions have been used for heart preservation during transplant procedures. Unfortunately, there is a lack of ideal method for myocardial preservation in the clinical practice. The use of retrograde cardioplegia provides continuous infusion of cardioplegic solution during the graft implantation. This strategy may provide better initial recovery of the graft. The objective of this study is to describe the experience of a single center where all patients received the same solution for organ preservation and were subjected to continuous retrograde blood microcardioplegia during implantation of the graft and to evaluate factors associated to early and late mortality with this technique.Methods: This is a retrospective, observational and descriptive study of a single center.Results: During the study period were performed 35 heart transplants. Fifteen (42.9%) patients were in cardiogenic shock. The probability of survival was 74.8±7.8%, 60.4±11.3% and 15.1±13.4% at 1 year, 5 years and 10 years of follow-up, respectively. The median survival time was 96.6 months.Conclusion: The use of myocardial protection with retrograde cardioplegic solution may reduce the risks associated morbidity due to cold ischemia time during the heart transplant, and we suggest that this benefit may be even greater in cases of cold ischemia time longer ensuring protection to the myocardium.Descriptors: Heart transplantation.

ResumoIntrodução: Uma grande variedade de técnicas e soluções é utilizada na preservação do coração durante o transplante, o que demonstra a falta de método ideal na prática clínica. A 348Lavagnoli CFR, et al. -Associated factors with survivals in patients undergoing orthotopic heart transplant using retrograde blood microcardioplegia Bras Cir Cardiovasc 2012;27(3):347-54 INTRODUCTION A variety of techniques and solutions are used in the preservation of the heart during transplantation, demonstrating the lack of ideal method in clinical practice [1]. RevIn the present day, where the number of donors is not enough, in addition to the increase of high-risk recipients on the waiting list, every effort should be made towards better organ preservation. A better organ preservation leads to lower graft dysfunction and promotes better late outcomes after transplantation [2,3].The use of retrograde blood cardioplegia has been described in several studies in the literature. There is no consensus whether this strategy promotes adequate myocardial protection [4]. Its use for the administration of blood cardioplegia during implantation is frequently reported in the literature. This strategy of cardioplegia administration allows for continuous perfusion o...

The myocardial protection allowed great advance in cardiac surgery, decreasing the mortality and making more feasible complex surgeries. Latterly the patient population elected for cardiac procedures has been changing towards elderly patients with ventricular function depressed and myocardial hypertrophy. The myocardial hypertrophy condition represents a great challenge since the beginning of the cardiac surgery. Several techniques have been described to protect the myocardial hypertrophy, however with no satisfactory results. In this manuscript we present the state of the art technique of myocardial protection. 98CRESSONI, ES ET AL -Myocardial protection to the hypertrophied heart: the eternal challenge Bras Cir Cardiovasc 2008; 23(1): 97-107 Rev
