BACKGROUND: The mechanisms of acid-base changes during cardiopulmonary bypass (CPB) remain unclear. We tested the hypothesis that, when used as CPB pump prime solutions, Plasma-Lyte 148 (PL) and Hartmann's solution (HS) have differential mechanisms of action in their contribution to acid-base changes. METHODS: We performed a prospective, double-blind, randomized trial in adult patients undergoing elective cardiac surgery with CPB. Participants received a CPB prime solution of 2000 mL, with either PL or HS...

OBJECTIVE: Del Nido cardioplegia (DC) offers prolonged cardiac protection with single dose administration and has been shown to be safe in adult CABG surgery. We set out to evaluate the efficacy of cardiac protection and clinical outcomes of del Nido cardioplegia versus standard blood cardioplegia (BC) in minimally invasive aortic valve surgery. METHODS: From 8/2011 to 5/2016, 178 patients underwent minimally invasive aortic valve replacement (AVR) with BC (n=101) or DC (n= 77)...

OBJECTIVES: Several studies have reported superior post-cardioplegic recovery after glutamate supplementation. The optimum dose of glutamate supplementation is unknown. The purpose of this study was to find the optimal protective concentration of glutamate supplementation in a model of ischaemia/cardioplegia and reperfusion. METHODS: Isolated rat hearts (n = 77) were perfused with the Krebs-Henseleit buffer. After stabilization, the hearts were subjected to 25 min of normothermic ischaemia followed by a single 3-min infusion of cold (4-6 °C) St...

We conducted a prospective randomized trial to compare del Nido (DN) cardioplegia with conventional cold blood cardioplegia (St Thomas [STH]) in pediatric patients. We randomized 100 pediatric patients aged ≤12 years undergoing elective repair of ventricular septal defects and tetralogy of Fallot to the DN and the STH groups. In the DN group, a 20 mL/kg single dose was administered. In the STH group, a 30 mL/kg dose was administered, followed by repeated doses at 25- to 30-minute intervals. The primary outcome was cardiac index that was measured 4 times intra- and postoperatively...

Cold agglutinins are autoantibodies that agglutinate red blood cells at low temperatures, leading to haemagglutination and haemolysis. They are generally of no clinical significance. However, when people with cold agglutinins undergo cardiac operation with hypothermia and cold cardioplegia, they can experience complications. Thus, different perioperative management is required for such patients. We describe a 74-year-old man with cold agglutinins incidentally detected on the preoperative screening test. He had never experienced any complications or developed a haematological disease...

OBJECTIVE: del Nido solution (DNS) is a single-dose cardioplegia designed for pediatric use proposed to offer superior myocardial protection in adults. However, few data support this claim. We hypothesized that DNS and modified blood cardioplegia solution (BS) provide equivalent safety in combined adult valve surgery. METHODS: Between November 2014 and December 2015, 25 patients underwent primary aortic valve replacement and concomitant coronary artery bypass grafting (CABG) with DNS...

Objective Blood cardioplegia, the gold-standard cardioprotective strategy, requires frequent dosing, resulting in hyperkalemia-induced myocardial edema. The aim of our study was to compare the efficacy and safety of a long-acting blood-based cardioplegia with physiological potassium levels versus the well-established cold blood St. Thomas' Hospital no. 1 cardioplegia solution in multivalve surgeries. Methods One hundred patients undergoing simultaneous elective aortic and mitral valve replacement ± tricuspid valve repair were randomized in two groups...

Cardioplegic reperfusion during a long-term ischemic period interrupts cardiac surgery and increases cellular edema due to repeated administration. The present clinical study compared the protective effects of histidine-ketoglutarate-tryptophan (HTK) solution and St. Thomas crystalloid cardioplegia. Clinical experiences of the myocardial protection induced by one single perfusion with HTK were reviewed in high-risk patients with severe pulmonary arterial hypertension associated with complex congenital heart disease...

OBJECTIVES: Cardioplegic arrest using a polarizing solution has been shown to have beneficial advantages for cardioprotection compared with depolarizing (potassium-based) arrest; most studies, however, have looked at normothermic ischaemia with short infusion intervals (every 10-15 min). This study examines the protective efficacy of an esmolol-based cardioplegia during hypothermic arrest, together with a prolonged infusion interval (30 min) for increased clinical feasibility. METHODS: Isolated Langendorff-perfused hearts were subjected to arrest with St Thomas' Hospital cardioplegia (STH2), or esmolol cardioplegia (single- or multidose infusion at 32°C) for 60-min, 90-min or 120-min global ischaemia at 32°C, and recovery of function (left ventricular developed pressure) measured...

Aortic valve replacement (AVR) for patients with functioning internal mammalian artery (ITA) grafts is technically challenging, and the optimal treatment strategy for these situations remains controversial. Here, we report five cases of AVR with ITA graft using continuous retrograde cardioplegia in addition to moderate hypothermia without the clamping of ITA and discuss the management of these cases.

The benefit of blood cardioplegia (BCP) compared to crystalloid cardioplegia (CCP) is still debatable. Our aim was to systematically review and synthesize all available evidence on the use of BCP and CCP to assess if any modality provides superior outcomes in pediatric cardiac surgery. A systematic literature search of the PubMed and Cochrane databases was performed with respect to the PRISMA statement (end-of-search date: January 30th, 2017). We extracted data on study design, demographics, cardioplegia regimens, and perioperative outcomes as well as relevant biochemical markers, namely cardiac troponin I (cTnI), lactate, and ATP levels at baseline, after reperfusion and postoperatively at 1, 4, 12, and 24 h as applicable...

OBJECTIVES: This study tested the hypothesis that remote perconditioning offers effective and synergistic cardioprotection to terminal warm blood cardioplegia for prompt ventricular recovery after prolonged cardioplegic arrest in an in vivo piglet model. METHODS: Twenty-four piglets were subjected to 120 min of single-dose cardioplegic arrest and were divided into 4 groups according to the mode of reperfusion: control (simple aortic unclamp), remote perconditioning, terminal warm blood cardioplegia or remote perconditioning + terminal warm blood cardioplegia; remote perconditioning (4 cycles of 5-min ischaemia-reperfusion of the lower limb) was applied prior to aortic unclamping...

Cardioplegia is an important strategy for myocardial protection during cardiac surgery. This meta-analysis was to compare the effects of del Nido and conventional cardioplegia in adult patients. Systematic searches were performed to identify studies using PubMed, Embase, the Cochrane Library, and the International Clinical Trials Registry Platform. A total of nine studies were included. Cardiopulmonary bypass and cross-clamp time were significantly shorter in the del Nido than conventional cardioplegia (mean difference [MD]: -7...

Low cardiac syndrome( LOS) is the imbalance of the oxygen supply and demand at the tissue due to reduced oxygen supply by decreased cardiac function. The causes of the cardiac dysfunction are insufficient cardioplegia, elongation of aortic clamp or cardiopulmonary bypass (CPB) duration, incomplete revascularization, and so on. The preventions of LOS are myocardial protections intraoperatively. The most important myocardial protection is to accomplish more quickly, accurately and safety to operation. And today, cardioplegia is essential for surgery requiring CPB...

Cardiac surgery with cardiopulmonary bypass and cardioplegic arrest is associated with injury to the vasculature and microcirculation leading to coronary microvascular dysfunction, permeability changes and cardiac dysfunction. In the setting of cardiopulmonary bypass with cardioplegia, poorly-controlled diabetes is associated with significant changes in endothelium-dependent and independent vascular dysfunction, vascular reactivity, vascular permeability, protein expression, cell death, coronary/peripheral microcirculation and reduced vasomotor tone leading to hypotension and impaired endothelial function...

Cardiac surgery on a patient with cold agglutinin disease is high risk for thromboembolism due to hypothermia perioperative. A 75-year-old woman with cold agglutinin disease underwent aortic valve replacement for severe aortic stenosis. Cold antibody was detected by preoperative screening test for blood transfusion. In order to prevent thromboembolic event during the operation, we maintained rectal temperature at around 36 degrees centigrade during the cardiopulmonary bypass by warming blood in the bypass circuit...
