E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the efficacy and safety of myocardial protection with a cardioplegic solution of the Nido, compared to the Buckberg cardioplegic solution in patients undergoing isolated aortic valve replacement. This efficacy on myocardial protection will be measured by comparing the levels of markers of myocardial injury (CK and Troponin T) between both strategies, as well as in-hospital mortality. |
Evaluar la eficacia y seguridad de la protección miocárdica con solución cardioplégica Del Nido, frente a la solución cardioplégica Buckberg en pacientes intervenidos de sustitución valvular aórtica aislada. Dicha eficacia sobre la protección miocárdica se medirá comparando los niveles de marcadores de lesión miocárdica (CK y Troponina T) entre ambas estrategias, así como mortalidad hospitalaria. |
|
E.2.2 | Secondary objectives of the trial |
To compare other markers of myocardial injury such as LVEF by transthoracic echocardiography, postoperative inotropic need, spontaneous recovery of the post-disinfestation cardiac rhythm or the need for defibrillation.
To compare other markers of hemodilution (minimum intraoperative and postoperative hemoglobin and need for transfusion), intra and postoperative glucose and insulin needs, other intraoperative analytical parameters such as intraoperative maximum lactate, aortic clamping times and CPB between both types of cardioplegia. |
Comparar otros marcadores de lesión miocárdica como FEVI por ecocardiografia transtorácica, necesidad de inotrópicos postoperatorios, recuperación espontanea del ritmo cardiaco post-despinzamiento o necesidad de desfibrilación.
Comparar otros parámetros marcadores de hemodilución (hemoglobina mínima intraoperatoria y postoperatoria y necesidad de transfusión), glucosa intra y postoperatoria y necesidades de insulina, otros parámetros analíticos intraoperatorios como lactato máximo intraoperatorio, tiempos de pinzamiento aórtico y CEC entre ambos tipos de cardioplegia. |

E.5 End points |
E.5.1 | Primary end point(s) |
Peak levels of CK in U / L and ultrasensitive Troponin T in ng / L in blood during the postoperative period: the levels of CK and Troponin T in blood will be determined in the first 24 hours postoperatively and later on a daily basis until the peak of both parameters is determined (usually occurs between 2 and 4 days postoperatively). The peak of CK and Troponin T of each of the study subjects will be recorded.
Operative mortality: Operative mortality will be considered, mortality within 30 days after surgery, or mortality during admission of the intervention (in patients whose hospital stay exceeds 30 days postoperatively). |
Niveles pico de CK en U/L y Troponina T ultrasensible en ng/L en sangre durante el postoperatorio: se determinarán los niveles de CK y Troponina T en sangre las primeras 24 horas postoperatorias y posteriormente de manera diaria hasta determinar el pico de ambos parámetros (usualmente se produce entre 2 y 4 días postoperatorios). Se registrará el pico de CK y de Troponina T de cada uno de los sujetos de estudio.
Mortalidad operatoria. Se considerará mortalidad operatoria, la mortalidad en los siguientes 30 días a la intervención quirúrgica, o la mortalidad durante el ingreso de la intervención (en pacientes en que el ingreso supere los 30 días postoperatorios). |

E.5.1.1 | Timepoint(s) of evaluation of this end point |

1 - 4 días y 30 días para cada variable primaria respectivamente |
|
E.5.2 | Secondary end point(s) |
Spontaneous recovery of aortic post-release rhythm: it will be recorded during the intraoperative period if there is spontaneous recovery of the heart rhythm when removing the aortic clamp. Need for post-aortic defibrillation: it will be recorded if defibrillation is necessary or not when removing the aortic clamp. Need for inotropes for CEC disconnection: the administration of inotropes for the CEC disconnection will be recorded if necessary or not. If yes, it will also be recorded what inotropes are necessary and in what dose. Minimum intraoperative hemoglobin (in g / L) Need for transfusion of red blood cells Maximum intraoperative glycemia (in mmol / L) Intraoperative insulin needs Insulin needs in the first 48 hours after surgery Maximum intraoperative lactate (in mmol / L) Aortic Impingement Time (minutes) Extracorporeal circulation time (minutes) Left ventricular function by echocardiography at discharge Left ventricular function by echocardiography at 3-6 months postoperatively |
Recuperación espontánea del ritmo post-despinzamiento aórtico: se registrará durante el periodo intraoperatorio si existe recuperación espontánea del ritmo cardiaco al retirar la pinza aórtica. Necesidad de desfibrilación post-despinzamiento aórtico: se registrará si es necesaria desfibrilación o no al retirar la pinza aórtica. Necesidad de inotrópicos para desconexión de CEC: se registrará si es necesario o no la administración de inotrópicos para la desconexión de CEC. En caso afirmativo, se registrará también qué inotrópicos son necesarios y en qué dosis. Hemoglobina mínima intraoperatoria (en g/L) Necesidad de transfusión de hematíes Glucemia máxima intraoperatoria (en mmol/L) Necesidades de insulina intraoperatoria Necesidades de insulina en las primeras 48 horas postoperatorias Lactato máximo intraoperatorio (en mmol/L) Tiempo de pinzamiento aórtico (minutos) Tiempo de circulación extracorpórea (minutos) Función ventricular izquierda por ecocardiografia al alta Función ventricular izquierda por ecocardiografia a los 3-6 meses postoperatorios |
