Normoxic versus Hyperoxic Reperfusion: A Retrospective Study of Ischemia–Reperfusion Injury in Patients Undergoing On-Pump Coronary Artery Bypass Grafting

April 1, 2026 No Comments

This retrospective study compared normoxic and hyperoxic reperfusion strategies in 50 patients undergoing elective on-pump CABG. Although oxygen delivery was similar between groups, normoxic management was associated with lower postoperative myocardial injury, better cardiac index, smaller declines in ejection fraction, and lower oxidative stress. The findings suggest that physiology-guided oxygenation may reduce ischemia–reperfusion injury during cardiopulmonary bypass.

The Impact of Re-operation on Aortic Arch Reconstructive Surgery: Evidence from a Multicentre, National Registry

April 1, 2026 No Comments

This multicenter Canadian registry study examined 2,481 patients who underwent aortic arch reconstruction between 2002 and 2021, including 374 redo cases after prior open-heart surgery. Despite a higher comorbidity burden, redo surgery was not associated with significantly higher overall operative mortality or major morbidity than primary surgery. Risk increased with older age, acute dissection or rupture, and longer cardiopulmonary bypass time.

Artificial Intelligence in Adult Cardiovascular Medicine and Surgery: Real-World Deployments and Outcomes

April 1, 2026 No Comments

Artificial intelligence (AI) is transforming adult cardiovascular medicine and surgery by enhancing diagnostics, surgical planning, intraoperative precision, and postoperative monitoring. Tools such as AI-ECG, automated imaging, and predictive analytics improve risk stratification and outcomes. While real-world deployments show promise, challenges including data quality, bias, and limited prospective validation remain barriers to widespread adoption.
