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

Brazilian Journal of Cardiovascular Surgery, 2012
INTRODUÇÃO: 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.

Evaluation of sanguineous and crystalloid cardioplegic solutions during total heart-lung bypass in dogs [PDF]

, 2009
Twenty-four mongrel dogs were subjected to sanguineous and crystalloid cardioplegia for a period of thirty minutes at 20°C and 25°C systemic hypothermia during cardiopulmonary bypass. Cardioplegic solutions were administered at 4°C to induce cardioplegia.

Coronary Artery Bypass Grafting on Microaxial Flow Pump Support in Patients With Severely Reduced Left Ventricular Ejection Fraction

Artificial Organs, Volume 49, Issue 8, Page 1346-1355, August 2025.
Coronary artery revascularization with microaxial flow pump support in patients with severely reduced left ventricular ejection fraction is an emerging technique in cardiac surgery. In this manuscript, we present early results, highlight the advantages, and discuss the key limitations of this approach.

Efeitos das cardioplegias sangüínea e cristalóide no miocárdio hipertrófico de coelho: avaliação estrutural e ultra-estrutural Effects of myocardial protection in hypertrophic rabbit hearts: structural and ultra structural analysis

Brazilian Journal of Cardiovascular Surgery, 2007
OBJETIVO: Comparar e avaliar experimentalmente as alterações estruturais e ultra-estruturais em corações hipertrofiados isolados de coelhos submetidos à parada protegida pela solução de cardioplegia sangüínea e cardioplegia cristalóide.

Long‐Term Outcomes of Mitral Valve Repair With Artificial Chordae and Annuloplasty for Myxomatous Mitral Valve Disease in Dogs

Journal of Veterinary Internal Medicine, Volume 39, Issue 4, July/August 2025.
ABSTRACT Background Myxomatous mitral valve disease (MMVD) in dogs commonly progresses to congestive heart failure, which carries a poor prognosis. Mitral valve repair (MVR) is a recognized treatment for advanced‐stage MMVD. Hypothesis/Objectives Identify the risk factors and prognosis in dogs undergoing MVR.

Trimetazidina como aditivo em solução cardioplégica sem pré-tratamento não traz proteção adicional ao miocárdio isquêmico: estudo em modelo suíno de coração isolado Trimetazidine as cardioplegia addictive without pre-treatment does not improve myocardial protection: study in a swine working heart model

Brazilian Journal of Cardiovascular Surgery, 2008
OBJETIVO: Verificar, em modelo experimental de coração isolado de suínos, se a associação da trimetazidina à solução cardioplégica promove melhora no desempenho do coração.

Histo-anatomical structure of the living isolated rat heart in two contraction states assessed by diffusion tensor MRI [PDF]

, 2012
Deformation and wall-thickening of ventricular myocardium are essential for cardiac pump function. However, insight into the histo-anatomical basis for cardiac tissue re-arrangement during contraction is limited.

St Thomas’ Hospital cardioplegic solution

The Journal of Thoracic and Cardiovascular Surgery, 1991
The intention of this study was to determine whether glucose is beneficial in a cardioplegic solution when the end products of metabolism produced during the ischemic period are intermittently removed. The experimental model used was the isolated working rat heart, with a 3-hour hypothermic 10 degrees C cardioplegic arrest period.

Association of plasma metabolites and cardiac mitochondrial function with heart failure progression

ESC Heart Failure, Volume 12, Issue 3, Page 2057-2065, June 2025.
Abstract Aims Plasma metabolites are prognostic in heart failure with reduced ejection fraction (HFrEF), with citric acid cycle metabolites linked to ejection fraction (EF) changes. We investigated these mechanisms in a canine chronic HFrEF model. We tested associations between changes in plasma metabolites, left ventricular (LV) end‐diastolic volume ...

Effects of cardioplegic solutions on conductive coronary arteries

The Journal of Thoracic and Cardiovascular Surgery, 1982
The effects of two cardioplegic solutions (CPSs) on isolated, superfused, bovine coronary arteries were compared with those produced by changes in composition of standard Krebs medium. High potassium, low sodium content or the addition of albumin produced vasoconstriction; high magnesium, high glucose content or the addition of mannitol led to ...
