Description: Hearts of very preterm infants have different physiological properties compared to term infants. Their left ventricle (LV) is relatively stiff, less compliant, and has restricted ability to handle afterload due to immaturity of the myocardium [1,2]. These unique developmental characteristics make cardiovascular compromise more likely in preterm infants when faced with hemodynamic challenges of the fetus to newborn transition and clinical complications of prematurity. Cardiovascular compromise and abnormalities of perfusion during neonatal period can potentially lead to increased mortality and long term morbidity. Hence, close monitoring of transitional circulatory changes and ongoing assessment of cardiovascular wellbeing is imperative in preterm infants.
