Ventricular Mass Index as a Reliable Method to Calculate Cardioplegia Volume [PDF]

Journal of Cardio-Thoracic Medicine
Introduction:  In cardiac surgery is essential protect myocardial tissue during cardiac arrest to perform the surgical procedure. The Cardioplegic solution has showed significant efficacy for myocardial protection by providing buffer mediators.

Transient dilutional acidosis but no lactic acidosis upon cardiopulmonary bypass in patients undergoing coronary artery bypass grafting

Archives of Medical Science, 2016
Introduction : Dilutional acidosis may result from the introduction of a large fluid volume into the patients’ systemic circulation, resulting in a considerable dilution of endogenous bicarbonate in the presence of a constant carbon dioxide partial ...

Prompt Graft Cooling Enhances Cardioprotection during Heart Transplantation Procedures through the Regulation of Mitophagy

Cells, 2021
A complete and prompt cardiac arrest using a cold cardioplegic solution is routinely used in heart transplantation to protect the graft function. However, warm ischemic time is still inevitable during the procedure to isolate donor hearts in the clinical

The relative buffering power of cardioplegic solutions

The Journal of Thoracic and Cardiovascular Surgery, 1987
Those factors that prolong myocardial tolerance to global ischemia constitute an important prerequisite for effective cardioplegia. This study contrasts the relative buffering power of bicarbonate-based and tromethamine-based hyperkalemic crystalloid cardioplegic solution with histidine protein-type buffer (Bretschneider) solution.

Custodiol HTK versus Plegisol: in-vitro comparison with the use of immature (H9C2) and mature (HCM) cardiomyocytes cultures

BMC Cardiovascular Disorders, 2022
Background Although cardioplegia is used since the ‘70s of the last century, debate on cardioprotection during cardio-surgical procedures is still actual. The selection of a particular method depends mainly on the preferences and experience of a specific

Panoramic voltage‐sensitive optical mapping of contracting hearts using cooperative multiview motion tracking with 12 cameras

The Journal of Physiology, EarlyView.
Abstact figure legend A panoramic 3D optical mapping system was developed, enabling imaging of action potential waves across the entire strongly deforming ventricular surface of beating isolated hearts. The system comprises 12 high‐speed cameras and a soccerball‐shaped imaging chamber with 48 light‐emitting diodes (LEDs).

The ultrarapid delayed rectifier potassium current has important functional role in the repolarization reserve of canine and human ventricular muscle

The Journal of Physiology, EarlyView.
Abstract figure legend The ultrarapid delayed rectifier potassium current (IKur) has long been considered an atrial‐specific current with no functional role in the ventricles, despite evidence of its expression in ventricular myocytes. In the present study we challenged this prevailing concept and investigated the potential role of IKur in ventricular ...

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.

Beneficial Effects of RNS60 in Cardiac Ischemic Injury

Current Issues in Molecular Biology, 2022
RNS60 is a physically modified saline solution hypothesized to contain oxygen nanobubbles. It has been reported to reduce ischemia/reperfusion injury in a pig model of acute myocardial infarction.
