Endothelium-dependent contraction of canine coronary artery is enhanced by crystalloid cardioplegic solution [PDF]

, 1995
Experiments were designed to determine whether hyperkalemic crystalloid cardioplegic solution enhances endothelium-dependent contraction of coronary arteries.

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

Early Multicenter Outcomes of Dedicated Transcatheter Aortic Valve Replacement for Left Ventricular Assist Device‐Associated Pure Aortic Regurgitation

Artificial Organs, EarlyView.
LVAD‐associated aortic regurgitation impairs circulatory support, with limited surgical and off‐label options. In a multicenter registry (n = 30), the AR‐dedicated JenaValve Trilogy TAVR eliminated AR, achieving 96.7% (29/30) technical success and 93.3% (28/30) device success (VARC‐3), with 3.3% (1/30) 30‐day mortality.

Preservation of myocyte contractile function after hypothermic, hyperkalemic cardioplegic arrest with 2,3-butanedione monoxime [PDF]

, 1996
One proposed contributory mechanism for depressed ventricular performance after hypothermic, hyperkalemic cardioplegic arrest is a reduction in myocyte contractile function caused by alterations in intracellular calcium homeostasis.

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).

Sedentary ageing remodels the structure–function relationships that underlie calcium signalling at super‐resolution scales in the heart

The Journal of Physiology, EarlyView.
Abstract figure legend Illustration of calcium spark function and ryanodine receptor (RyR) structure within a sedentary model of ageing. Upon sympathetic stimulation from 1 µM isoprenaline a linear response to calcium spark morphology occurred, accompanied by a biphasic progression of RyR remodelling across age.

Role of sodium pump activity in warm induction of cardioplegia combined with reperfusion of oxygenated cardioplegic solution [PDF]

, 1995
Na+/K+ adenosinetriphosphatase (sodium pump) may play a key role in the prevention of reperfusion injury caused by Ca2+ overload. The present study was undertaken to investigate the role of sodium pump activity in warm induction of cardioplegia combined ...

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.

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 ...
