Why the study?
Quantifying myocardial protection in cardiac surgery is difficult because geometric remodeling creates mismatch between body weight and heart weight.
Does indexing myocardial protection volume to left ventricular mass index rather than body surface area reduce post-operative low cardiac output syndrome in adults undergoing elective valvular cardiac surgery?
Does indexing myocardial protection volume to left ventricular mass index rather than body surface area reduce post-operative low cardiac output syndrome in adults undergoing elective valvular cardiac surgery?
Indexing myocardial protection volume to left ventricular mass index rather than body surface area reduces post-operative low cardiac output syndrome and improves early myocardial recovery in patients undergoing elective aortic valve surgery.

Indexing cardioplegia to LVMI may lower LCOS in valvular surgery; extends mass-based dosing beyond BSA in RCTs.
