Influence of cardioplegia techniques on outcomes after aortic valve replacement

Dual anterograde and retrograde cardioplegia delivery, warm induction and hotshot delivery had previously been shown to confer myocardial protection, but have not been studied for over a decade. High-sensitivity troponins (hs-Tn) are now the recommended biomarkers for assessing myocardial necrosis. We compared the degree of hs-TnT release and outcomes of aortic valve replacement (AVR) by these cardioplegia techniques.
