TY - CHAP M1 - Book, Section TI - Development of the Cardiovascular System A1 - Srivastava, Deepak A2 - Kline, Mark W. Y1 - 2018 N1 - T2 - Rudolph's Pediatrics, 23e AB - Cardiogenesis involves a precisely orchestrated series of molecular and morphogenetic events that combines cell types from multiple lineages. Subtle perturbations of this process can result in life-threatening congenital heart defects (CHDs). As an organ essential for life, the heart is the first organ to form and must support the rapidly growing embryo before it has the opportunity to become a four-chambered organ. The combination of the complex morphogenetic events necessary for cardiogenesis and the superimposed hemodynamic influences may contribute to the exquisite sensitivity of the heart to perturbations as reflected in the estimated 10% incidence of severe cardiac malformations observed in early miscarriages. The fraction of congenital heart malformations that are compatible with development composes the spectrum of CHD observed clinically in nearly 1% of live births. An additional 1% to 2% of the population harbor more subtle cardiac developmental anomalies that only become apparent as age-dependent phenomena reveal the underlying pathology. A more precise understanding of the causes of CHD is imperative for the recognition and potential intervention of progressive degenerative conditions, such as heart failure, among survivors of CHD.
