Comparison of three cardioplegic solutions during hypothermic ischemic arrest in neonatal blood-perfused rabbit hearts.

Journal of Thoracic and Cardiovascular Surgery, 1989
Inadequate myocardial preservation continues to be an important cause of postoperative morbidity and mortality after pediatric cardiac operations. To investigate methods of improving preservation in neonatal myocardium, we compared three cardioplegic ...

Beat‐to‐beat variability of ventricular repolarization reveals sex‐specific instability and proarrhythmic risk

The Journal of Physiology, EarlyView.
Abstract figure legend A mechanistic framework linking sex‐dependent dynamical instability to proarrhythmic risk. Sex‐specific human ventricular models show that upstream modulators, including biological sex, hormones, drugs and heart disease, promote steeper APD restitution in female than male and enhance dynamical instability.

Effect of different cardioprotective methods on extracorporeal circulation in fetal sheep: a randomized controlled trial

Journal of Cardiothoracic Surgery, 2021
Background Congenital heart disease is a leading cause of death in newborns and infants. The feasibility of fetal cardiac surgery is linked to extracorporeal circulation (ECC); therefore, cardioplegic solutions need to be effective and long-lasting ...

Asymptomatic Giant Right Ventricular Myxoma in an Adolescent: A Rare Case Report With Favorable Surgical Outcome

Journal of Clinical Ultrasound, Volume 54, Issue 7, Page 1790-1794, September 2026.
We report a 13‐year‐old female with a giant right ventricular myxoma extending to the pulmonary trunk. The tumor was diagnosed by multimodal imaging and completely resected, with favorable short‐term outcomes. ABSTRACT Right ventricular (RV) myxomas account for < 5% of cardiac myxomas and are often asymptomatic, easily overlooked.

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.

The use of blood and crystalloid cardioplegia in adult open-heart surgery on postsurgical outcomes: A systematic review of atrial fibrillation incidence, myocardial infarction, inotropic use, length of stay in ICU, and postoperative mortality

Bali Journal of Anesthesiology, 2022
Background: Myocardial ischemia can occur due to hypotension, shock, coronary heart disease, and aortic cross-clamping during open-heart surgery using a cardiopulmonary bypass machine. As the cardioprotective method, cardioplegia is classified into blood

Four‐Chamber Deformation Remodeling and Atrial Fibrillation After Septal Myectomy for Obstructive Hypertrophic Cardiomyopathy

Echocardiography, Volume 43, Issue 8, August 2026.
After septal myectomy for hypertrophic obstructive cardiomyopathy, the four chambers of the heart experience unique remodeling patterns that can be visualized with speckle‐tracking strain analysis on echocardiography. This study characterizes those changes and links them to clinical outcomes such as post‐operative atrial fibrillation risk, thereby ...

Higher sensitivity to ouabain‐induced toxicity in human induced pluripotent stem cell‐derived cardiomyocytes than human adult heart tissue despite similar Na+/K+‐ATPase pump current amplitudes

British Journal of Pharmacology, Volume 183, Issue 11, Page 3093-3110, June 2026.
Abstract Background and Purpose Human induced pluripotent stem cell‐derived cardiomyocytes (hiPSC‐CM) have gained interest as a pharmacological model but their immaturity leads to uncertainty regarding translation. We studied the key player in maintaining ionic homeostasis, the Na+/K+‐ATPase (NKA), in hiPSC‐CM.
