Key Echocardiographic Features • Thickened, doming aortic valve. • Ascending aorta may be dilated in isolated aortic stenosis; however, aortic hypoplasia is common when aortic stenosis is seen in the…

Key Echocardiographic Features • Absence of competent aortic valve tissue at the site of the aortic annulus. • Abnormally prominent pulsation of the ascending aorta. • Abnormal dilation of the…

Key Echocardiographic Features • Site of narrowing of the arch • Associated anomalies such as aortic stenosis, subaortic narrowing, left ventricular hypoplasia, or ventricular septal defect • Mitral valve size…

Ultrasound assessment of the fetal cardiovascular system is a challenging but very rewarding process. Although the term fetal echocardiography may imply assessment of the fetal heart alone, much information is…

Key Echocardiographic Features • Location of defect on the ventricular septum. • Size of defect in relation to aortic annulus. • Direction of shunting across the defect. • Presence or…

Key Echocardiographic Features • Presence or absence of great vessels crossing as they course just above the heart. • Relationship of the great vessels to each other as they arise…

Key Echocardiographic Features • Position of the morphological right ventricle on the left, giving rise to the aorta, and the morphological left ventricle on the right, giving rise to the…

Key Echocardiographic Features • Position of the conal septum in relation to the ventricular septum and size of the ventricular septal defect created • Degree of posterior deviation of the…

Key Echocardiographic Features • Large malalignment type of ventricular septal defect. • Single semilunar valve, that of the aorta, arising from the heart. • No antegrade flow into the pulmonary…
