Abstract

Aims: Initially developed for myocardial protection in immature cardiomyocytes, del Nido cardioplegia has been increasingly used over the past decade in adult patients. Our aim is to analyse the results from randomized controlled trials and observational studies comparing early mortality and postoperative troponin release in patients who underwent cardiac surgery using del Nido solution and blood cardioplegia.

Methods: A literature search was performed through three online databases between January 2010 and August 2022. Clinical studies providing early mortality and/or postoperative troponin evaluation were included. A random-effects meta-analysis with a generalized linear mixed model, incorporating random study effects, was implemented to compare the two groups.

Results: Forty-two articles were included in the final analysis for a total of 11 832 patients, 5926 of whom received del Nido solution and 5906 received blood cardioplegia. del Nido and blood cardioplegia populations had comparable age, gender distribution, history of hypertension and diabetes mellitus. There was no difference in early mortality between the two groups. There was a trend towards lower 24 h [mean difference -0.20; 95% confidence interval (CI) -0.40 to 0.00; I2 = 89%; P = 0.056] and lower peak postoperative troponin levels (mean difference -0.10; 95% CI -0.21 to 0.01; I2 = 0.87; P = 0.087) in the del Nido group.

Conclusion: del Nido cardioplegia can be safely used in adult cardiac surgery. The use of del Nido solution was associated with similar results in terms of early mortality and postoperative troponin release when compared with blood cardioplegia myocardial protection.
