Chapter 6 Congenital Heart Disease and Circulatory Physiology Takashi Honda 1 Kagami Miyaji2 and Masahiro Ishii1 Department of Pediatrics Kitasato University School of Medicine Japan 2Department of Cardiovascular Surgery Kitasato University School of Medicine Japan Abstract The physiological basis of congenital heart diseases in most cases is an abnormality in hemodynamics. Therefore a timely diagnosis based on echocardiography has contributed to the medical practice for patients with congenital heart diseases. Echocardiography has clarified not only the hemodynamics of children but also that of fetuses and fetal therapies based on the fetal echocardiography findings are now being developed. The technical innovations in echocardiography are remarkable. Vector flow mapping echocardiography made it possible to visualize the blood flow and to analyze the energy dynamics. Cardiac magnetic resonance imaging is also a promising imaging modality because a three-dimensional evaluation and an assessment of the myocardial characteristics are possible without limitations such as poor echo window which often affects the hemodynamic evaluation on echocardiography. Owing to recent innovations in diagnosis medical treatment and surgical techniques long- term survival can be expected even in patients with complex congenital heart diseases. At present we are consequently facing new problems regarding the medical practice for adult patients after surgeries for Tetralogy of Fallot and single ventricular anomalies. The accumulation of knowledge on the hemodynamics in these adult patients will show us the direction that should be taken to overcome long-term life-threatening complications. In this chapter we discuss the characteristics of the hemodynamics in patients with CHD from fetus to adult and propose ways to .
