We tested the hypothesis that triiodothyronine (T3) supplementation alters gene transcription in the left ventricular myocardium of infants undergoing cardiopulmonary bypass for ventricular septal defect repair. To our knowledge, a novel heteronuclear assay demonstrated for the first time in human heart that rapid change in T3 levels altered the adenine nucleotide translocase-1 transcription rate during cardiopulmonary bypass.

Background: Coronary artery bypass grafting (CABG) surgery has been a widely accepted method for treating coronary artery disease. However, its postoperative complications can have a significant effect on long-term patient outcomes. A retrospective study was conducted to identify before and after surgery that contribute to postoperative stroke in patients undergoing CABG, and to develop predictive models and recommendations for single-factor thresholds.

Background: Acute kidney injury (AKI) occurs in up to 50% of cardiac surgical patients and is often hemodynamically mediated. Point-of-care ultrasound is a non-invasive tool that has the potential to characterize intrarenal hemodynamics and predict the risk of AKI.
Objectives: We aimed to determine the predictive characteristics of intrarenal arterial and venous Doppler markers for postoperative AKI in cardiac surgical patients.

The patient an 85-year-old female resided in a care facility where she maintained an independent daily activity level. She was discovered hunched over a table in her room, displaying reduced responsiveness and prompting an emergency call. Initially, her blood pressure was within 60 mmHg, and she was transported by ambulance to our hospital.

Background Children with Down syndrome (DS) often have hypoplastic kidneys and urinary tract malformations that increase their renal dysfunction risk. They also have a higher congenital heart disease (CHD) rate, requiring cardiac surgery during infancy. Renal dysfunction in such patients may be associated with the development of cardiac surgery-associated acute kidney injury (CS-AKI), but this remains unclear.

Background The adoption of minimally invasive cardiac surgery (MICS) has increased over the past 25 to 30 years, driven by advancements in technology and a growing understanding of its benefits. This study evaluates the outcomes of 144 elective MICS procedures performed between January 2019 and September 2024. Methods Patients underwent various surgical approaches, including upper mini-sternotomy, mini-thoracotomy, and sub-xiphoid access.
