The cardioprotective effects of HTK solution and conventional blood cardioplegia in patients with atrial fibrillation undergoing valvular replacement and Cox maze III procedure.
J Cardiothorac Surg
January 2025
Department of Anesthesiology, Women's Hospital of Nanjing Medical University, Nanjing Women and Children's Healthcare Hospital, No. 123, Tianfei Lane, Mochou Road, Nanjing, Jiangsu, 210004, China.
Introduction: The study was to assess the myocardial protection effects of the histidine-tryptophan-ketoglutarate (HTK) solution and the 4:1 blood cardioplegia (BC) in patients with atrial fibrillation (AF) who were subjected to valvular replacement concomitant with the Cox maze III surgery.
Methods: A cohort of 148 individuals afflicted with AF, who received valve replacement surgery in conjunction with the Cox maze III procedure at our clinic within the period extending from 2015 to 2023, were enrolled. Subsequent to adjustment by propensity score matching (PSM), the patients were categorized into two distinct groups: the HTK group and the BC group.
A Novel Machine Perfusion System for Enhancing Hepatic Microcirculation Perfusion.

Background: Machine perfusion is a promising strategy for safeguarding liver transplants donated after cardiac death (DCD). In this study, we developed and validated a novel machine perfusion approach for mitigating risk factors and salvaging severe DCD livers.
Methods: A novel hypothermic oxygenated perfusion (HOPE) system was developed, incorporating two pumps and an elastic water sac to emulate the functionality of the cardiac cycle.
Preservation solution protects isolated hair micrografts by inhibiting apoptosis of hair bulb.

Department of Plastic and Aesthetic Surgery, Nanfang Hospital, Southern Medical University, Guangzhou, Guangdong Province 510515, China. Electronic address:
Aims: To investigate the effectiveness of histidine-tryptophan-ketoglutarate (HTK) solution compared to Ringer's (RS) solution for preserving isolated hair follicles (HFs), focusing on structural integrity, cell viability, apoptosis prevention, and identifying the mechanisms of cell death during the preservation period.
Materials And Methods: Isolated human HFs were preserved in HTK or RS solution for periods ranging from 2 to 12 h. Morphological changes were assessed using H&E staining and transmission electron microscopy (TEM).
HTK Solution Cardioplegia in Pediatric Patients: A Meta-analysis.

November 2024
Prevent Senior Private Health Operator, Sao Paulo, Brazil.
Introduction: Cardioplegia, a therapy designed to induce reversible cardiac arrest, revolutionized cardiovascular surgery. Among the various pharmacological approaches is the histidine-tryptophan-ketoglutarate (HTK) solution. Despite numerous studies, no meta-analysis has investigated the efficacy of the HTK solution in the pediatric population.

Article Synopsis
- Minor defects in the mitochondrial ATP-generating system can harm heart function in immature hearts, so this study explored various cardioplegic solutions.
- The experiment involved 41 male rats and compared the effects of three solutions (St. Thomas, Custodiol HTK, and Del Nido) during 1-hour and 3-hour ischemic periods.
- Results showed that the Del Nido solution offered the best mitochondrial respiration and ATP production compared to the other solutions, particularly after extended ischemia.
