Impact of Del Nido Versus Blood Cardioplegia on Myocardial Viability Assessed With Magnetic Resonance Imaging

Detaljeret beskrivelse
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.
