Hyperglycaemia‐induced reactive oxygen species production in cardiac ventricular myocytes differs among mammals

The Journal of Physiology, Volume 604, Issue 16, Page 6792-6816, 15 August 2026.
Abstract figure legend In rat and human adult ventricular myocytes, acute hyperglyceaemia (Glucose) causes increased glucose uptake (via GLUT) leading to O‐GlcNAcylation of CaMKII at Ser280, such that CaMKII activates NADPH oxidase 2 (NOX2) to increase cytosolic reactive oxygen species (ROS). That perturbs the ROS to Antioxidant (AntiOx) balance.

Retrograde crystalloid cardioplegia preserves left ventricular systolic function better than antegrade cardioplegia in patients with occluded coronary arteries [PDF]

, 2000
Objective: To investigate retrograde and antegrade crystalloid cardioplegia in terms of cardiac cooling and postoperative cardiac function. Design: Prospective, randomized, and blinded. Setting: University hospital.

Simultaneous Transvenous Lead Extraction and Intra‐Operative Epicardial Extravascular Defibrillator (EV‐ICD) Implantation During Tricuspid Valve Replacement

Clinical Case Reports, Volume 14, Issue 7, July 2026.
ABSTRACT Transvalvular device leads are undesirable following tricuspid valve replacement. Simultaneous lead extraction and intra‐operative EV‐ICD implantation can provide ongoing defibrillator therapy without crossing the prosthetic valve and may avoid the need for additional pacing hardware when atrioventricular conduction is preserved.

Retrograde cardioplegia in CABG: Is it really useful? The microcirculation and a capillary unit model [PDF]

, 2006
Most surgeons, ourselves including, use retrograde cardioplegia in numerable operations in cardiac surgery. It is believed to be not only supplementary to antegrade, but also a unique alternative in special complicated cases.

From Donor Liver to Recipient Pulmonary Artery: Embolization of a Transected Central Venous Catheter During Liver Transplantation, A Rare Complication of Organ Procurement

Clinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT Central venous catheters (CVCs) are essential in transplantation but can rarely fracture and embolize, with donor‐to‐recipient transmission of catheter fragments scarcely described. A 62‐year‐old woman with hepatitis C–related cirrhosis and hepatocellular carcinoma underwent orthotopic liver transplantation from a brain‐dead donor with a left ...

Supplemental cardioplegia immediately before graft implantation may improve early post-transplantation outcome [PDF]

, 2015
Gebiet: Chirurgie Abstract: Background: Preservation of cardiac grafts for transplantation is not standardized and most centers use a single administration of crystalloid solution at the time of harvesting.

A Rare Case of Complicated Kommerell's Diverticulum in a Middle‐Aged Woman

Clinical Case Reports, Volume 14, Issue 5, May 2026.
ABSTRACT Kommerell's Diverticulum is a rare vascular anomaly that can manifest as an anterior mediastinal mass. Considering its rarity and possible lethal complications, it is crucial to consider this abnormality when dealing with anterior mediastinal vascular lesions.
