Morphological and topographical variations of the outlet chamber in complex congenital heart disease: an angiocardiographic study.

摘要: The outlet chamber of the human heart can show considerable variations in its morphology and topography (relationship to main ventricular chamber), such anatomy spacial relationship may be predictive associated intracardiac anatomy. Although there is debate about whether position indicative type bulboventricular loop (whether D- or L-), a right-sided anterior has different implications than left-sided, superior, more posterior positioned one. inflows into vary anatomically, progressive changes calibers these communications adversely alter natural history. One both greak vessels, neither, persistent truncus arteriosus originate from chamber, any significant morphological change not affect either pulmonary systemic blood supply, both. Finally, consideration raises important conceptual difference terminologies. At present, unanimity as what constitutes an (as compared “small right ventricle” tricuspid atresia) single (primitive) ventricle. Any discussion topographical must viewed with respect terminology employed.
