Comparing two types of cardioplegia in major heart surgery

Official title: Evaluation of Clinical Impact of the Type of Cardioplegia Used in the Patient Undergoing Major Cardiac Surgery with Extracorporeal Circulation. CARDIO-HEART Clinical Trial.

Run by Hospital San Carlos, Madrid · NCT06530641 · Data updated 2026-11-12

This study tests whether a type of heart surgery solution called Custodiol works just as well as another solution, Buckberg, in protecting the heart during major surgeries.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults over 18 years old with cardiac conditions requiring major surgery involving extracorporeal circulation.

Probably not a fit

Patients with conditions such as pregnancy, aortic arch procedures, or those undergoing minimally invasive surgeries may not benefit from this study.

What this trial studies

This phase IV clinical trial is a single-blind, prospective, and longitudinal randomized intervention that compares the effects of Custodiol crystalloid cardioplegia and Buckberg blood cardioplegia in patients undergoing major cardiac surgery with extracorporeal circulation. The study aims to evaluate the non-inferiority of Custodiol cardioplegia, particularly in complex surgeries requiring longer aortic clamping times. By addressing the lack of standardized consensus on cardioplegia use, this trial seeks to provide clearer guidance on myocardial protection strategies during cardiac surgery. The trial will involve patients over 18 years of age with specific cardiac pathologies indicated for surgery.

Why it matters

Potential benefit: If successful, this study could lead to improved myocardial protection strategies during major cardiac surgeries, enhancing patient outcomes.

How similar studies have gone: While there is limited literature on this specific comparison, previous studies have shown varying outcomes with different cardioplegia methods, indicating the need for further investigation.
