Myocardial preservation in the neonate. Beneficial effects of cardioplegia and systemic hypothermia on piglets undergoing cardiopulmonary bypass and myocardial ischemia.


This study examined anatomic differences between the adult and the newborn heart as they relate to myocardial preservation and compared standard techniques of myocardial preservation used in operations for congenital heart disease. The biventricular endocardial surface area/ventricular mass ratios were calculated in 10 neonatal (2.5 +/- 0.2:1) and 10 adult… (More)
