Tetralogy of Fallot is a complex congenital heart defect characterized by a large ventricular septal defect (hole between the right and left ventricles), pulmonary stenosis (narrowing of the valve and artery that connect the heart with the lungs), an overriding aorta (the aorta - the artery that carries oxygen-rich blood to the body - is shifted over the right ventricle Tetralogy of Fallot. View PDF external link opens in a new window Intensity of murmur depends on size of VSD and flow across the VSD. A small VSD has a louder murmur because the gradient between the right and left ventricles is higher. A large VSD has a soft murmur because pressures are equalised between the right and left ventricles. It is the Diagnosis of tetralogy of Fallot and its variants in the late first and early second trimester: details of initial assessment and comparison with later fetal An echocardiogram revealed findings consistent with significant pulmonary arterial hypertension, which was found to be responsive to inhaled nitric oxide. were recorded in 1,482 ultrasound examinations.
