Mitral valve surgery after previous cardiac surgery is technically demanding and risky. In patients after coronary artery bypass grafting (CABG), mitral valve surgery is associated with a high risk of injury to the bypass graft with concomitant myocardial ischemia.
The pathophysiology of AKI in ECMO is multifactorial, and includes ischaemia, RBCs breakdown, comorbidity, conversion of zymogen form of pro‐inflammatory mediators, structural alteration of the kidney, coadministration of nephrotoxic drugs, coagulation abnormality, and oxidative stress.
