NCT06235424

Brief Summary

The goal of this clinical trial is to compare del Nido and Bretschneider-HTK (HTK) cardioplegia solutions in patients undergoing elective aortic valve replacement. The main question it aims to answer is: • Does the del Nido cardioplegia provide better cardioprotection and clinical outcomes than HTK cardioplegia? Participants will receive one of the investigated cardioplegia solutions according to the randomization. Researchers will compare both groups in terms of cardioprotection (described as levels of CK-MB and hsTnI), in-hospital clinical outcomes, biochemical changes in coronary sinus blood and one-year follow-up.

Study Arms (2)

del Nido cardioplegia group

ACTIVE COMPARATOR

A group of patients that received high potassium cardioplegic solution with the addition of lidocaine, mixed with the patient's blood in 4:1 ratio

Drug: Del Nido Cardioplegia Solution

Bretschneider-HTK cardioplegia group

ACTIVE COMPARATOR

A group of patients that received low sodium cardioplegic solution with the addition of histidine, tryptophan and alpha-ketoglutarate

Drug: HTK solution

Interventions

The route of cardioplegia delivery differed according to surgeons' preferences. The total dosage of cardioplegia depends on the type of cardioplegia. The standard dose of del Nido cardioplegia in our institution is 1000 ml as an initial dose and is delivered with a system pressure of 90-150 mmHg. The solution is prepared by our hospital's pharmacy. At 60. minute of cross-clamp (XC) if XC time was expected to exceed 90 minutes another dose of solution would be delivered. The volume of an additional dose was 500 ml. The temperature of the delivered del Nido cardioplegia was 4\*C.

del Nido cardioplegia group

The route of cardioplegia delivery differed according to surgeons' preferences. The dose of the HTK cardioplegia is calculated with an application of 20 mL/kg rule. It is delivered with a system pressure of 90-150 mmHg. If the XC time exceeds 120 minutes additional dose is given (10 mL/kg rule). The temperature of the delivered crystalloid cardioplegia is 4\*C
