Buckberg vs Del Nido in Isolated Aortic Valve Replacement

Del Nido cardioplegic solution administered in a single dose at 15-20mg/Kg with a maximum dose of 1L of solution, administered antegrade or retrograde. In those patients in wich the crossclamping time exceed 90 to 120 minutes a manteinance dose of 500ml will be administered.

Buckberg cardioplegical solution administered antegrade and/or retrograde at 1-2ml/Kg for cardiac arrest induction. Arrest manteinance with antegrade and/or retrograde administration at 1-2ml/Kg every 15 to 20 minutes. Reperfusion dose with antegrade or retrograde administration at 15-20 ml/Kg before removing the aortic crossclamp.
