Experimental Study of Cold Blood Cardioplegic Solution. Is Cold Blood Cardioplegic Solution made Effective by the Red Blood Cell? [PDF]

, 1995
This sutudy was designed to distinguish whether the efficacy of blood cardioplegic solution is due to a celluler or plasma component. Japanese white rabbits' hearts were preserved for 3 hours by coronary perfusion with oxygenated crystalloid 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.

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.

Is cardioplegic rearrest safe?

, 1981
In cardiac bypass procedures the use of anoxic arrest or ventricular fibrillation is known to cause severe myocardial damage. The authors have investigated the safety of using cardioplegic rearrest when surgical difficulties are encountered at the end of

Comparative Analysis of Myocardial Protection with HTK Solution and Hypothermic Hyperkalemic Blood Solution in the Correction of Acyanogenic Congenital Cardiopathies - A Randomized Study

Brazilian Journal of Cardiovascular Surgery
Objective: The goal of the present study was to compare the myocardial protection obtained with histidine-tryptophan-ketoglutarate (HTK) cardioplegic solution (Custodiol®) and with intermittent hypothermic blood solution.

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.

AP‐1‐Targeting Decoy Oligonucleotides: Mechanisms and Therapeutic Potential as Modulators of Inflammatory Pathways

Journal of Cellular and Molecular Medicine, Volume 30, Issue 9, May 2026.
ABSTRACT Numerous cellular functions, such as apoptosis, proliferation, differentiation, survival, transformation and cell migration, are regulated by a crucial transcription factor called activator protein 1 (AP‐1). Growing evidence indicates that AP‐1 is involved in severe conditions like fibrosis, cancer, and organ damage, as well as inflammatory ...

ULTRASTRUCTURAL PATHOLOGY OF PEDIATRIC MYOCARDIUM IN ACUTE ISCHEMIA. BIOPTIC STUDY AND AFTER TREATMENT WITH CARDIOPLEGIC SOLUTION

, 2006
Protecting the myocardium from the risk of acute ischemia during heart surgery is still an unsolved problem; the problem is even more open and more pressing in pediatric heart surgery, To meet this greater risk it is advisable to use a cardioplegic ...

Rescue Balloon Pulmonary Angioplasty Prior to Pulmonary Endarterectomy With Concomitant Mitral Valve Plasty in High‐Risk Operable CTEPH

Pulmonary Circulation, Volume 16, Issue 2, April 2026.
ABSTRACT Pulmonary endarterectomy (PEA) is a potentially curative treatment for chronic thromboembolic pulmonary hypertension (CTEPH); however, decompensated right heart failure and concomitant cardiac procedures increase the risk of postoperative mortality. We report a case of operable CTEPH with severe mitral regurgitation causing right heart failure
