Study Overview
Brief Summary
Myocardial protection during surgical myocardial revascularization is crucial for reducing perioperative myocardial injury and improving postoperative outcomes. Blood cardioplegia represents the standard method in many centers, while del Nido cardioplegia, originally developed for the pediatric population, is increasingly being used in adult patients as well.
Detailed Description
Previous studies have demonstrated reliable myocardial protection with Del Nido cardioplegia; however, most comparisons with conventional blood cardioplegia are based on biochemical markers (troponin, CK-MB) and echocardiography. Cardiac magnetic resonance imaging (CMR) enables noninvasive, highly sensitive assessment of left ventricular function as well as myocardial viability, edema, and fibrosis, and represents the gold standard for the evaluation of ventricular volumes and ejection fraction. To date, this imaging modality has not been used as a method for comparing different myocardial protection strategies in the context of various cardioplegic solutions.
The study will include patients with isolated coronary artery disease who are scheduled for surgical myocardial revascularization. Exclusion criteria will include the need for concomitant valve, aortic, or other cardiac surgery, as well as patients planned for myocardial revascularization without the use of cardiopulmonary bypass. Additionally, patients with contraindications to CMR will be excluded from the study.
