Study Overview
Brief Summary
Cardioplegia solutions have been used for myocardial protection in cardiac surgery for decades. Different cardioplegic strategies have been evaluated.
Del Nido cardioplegia was initially used in pediatric patients and has been expanding into adult cardiac centers over the last decade. It can be used as a single dose and it is a reasonable tool do decrease cardioplegic interventions. Recent meta-analysis based on 9 retrospective studies has shown that "clinical outcomes of Del Nido cardioplegia are noninferior to the outcomes of conventional cardioplegia in adult cardiac surgery".
To assess the potencial benefits of Del Nido cardioplegia we performed this clinical trial to evaluate superiority of Del Nido cardioplegia compared to cold blood cardioplegia in terms of myocardial protection and clinical-related outcomes. 474 participants will be randomized either into Del Nido cardioplegia protocol or into the cold blood cardioplegia protocol. Perioperative outcomes will be presented.
Detailed Description
This clinical trial is performed at Puerta de Hierro Hospital in Spain. The protocol has been approved by institutional ethical committee and Spanish Agency of medicines and medical devices (AEMPS).
The aim of the study is to evaluate superiority of Del Nido cardioplegia solution compared to cold blood cardioplegia solution in terms of myocardial protection and clinical-related outcomes.
According to results in recent meta-analysis, the author estimated a total sample size of 474 participants to give 80 % of power at the 5% significant level.
Participants aged 18 years or older undergoing elective cardiac surgery are randomized 1:1 to receive Del Nido cardioplegia solution (study group) and cold blood cardioplegia solution (control group).
Primary outcome will be assessed by biochemical variables of myocardial injury (troponin T level at inmediate post-op, 3-12 hours, 12-24 hours, 24-48 hours post-op); and clinical variables: "Presence of acute myocardial infarction within 72 hours after surgery", "Prolonged low cardiac output", "Prolonged postoperative vasoplegia" within 48 hours after surgery and/or "Ventricular tachyarrythmias" within 24 hours after surgery.

Arms & Interventions
Del Nido Cardioplegia solution
1 liter of Del Nido cardioplegia after aortic cross-clamp will be given. Additional dose will be applied if aortic cross-clamp exceeds 90 minutes or whenever cardiac activity is observed.
Intervention: DEL NIDO CARDIOPLEGIA (Drug)
Cold blood Cardioplegia solution
Administering of cardioplegia using current standard of care blood-based cardioplegia protocol. An induction dose of whole blood cardioplegia will be given at a temperature of 4-8 degrees, with subsequent doses of cardioplegia every 20 minutes or whenever cardiac activity is observed.
Intervention: COLD BLOOD BASED CARDIOPLEGIA (Drug)
