Myocardial Protection Efficacy of Custodiol, Del Nido, and Cold Intermittent Blood Cardioplegia in Arterial Switch Operation.

ABSTRACT:

Objectives

The arterial switch operation (ASO) is the standard treatment for transposition of the great arteries (TGA), requiring robust myocardial protection due to the neonatal myocardium's vulnerability to ischaemia. This study compares the myocardial protective efficacy of Custodiol, Del Nido, and cold intermittent blood cardioplegia in neonates undergoing ASO.

Methods

We retrospectively analysed 133 neonates with TGA undergoing ASO (2013-2024) at 4 Turkish centres, grouped by cardioplegia: cold blood (n = 47), Custodiol (n = 44), or Del Nido (n = 42). Outcomes included aortic cross-clamp and cardiopulmonary bypass times, troponin I, CK-MB, inotropic support, and ventilation duration.

Results

Custodiol and Del Nido had shorter cross-clamp (70.4 (8.5) vs 68.7 (7.9)
