Dec 7, 2024 · Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart condition with many cases presenting after the newborn period. It has been classically characterized by the combination of ventricular septal defect (VSD), right ventricular outflow tract obstruction (RVOTO), overriding aorta, and late right ventricular hypertrophy.

Tetralogy of Fallot has four major components: · Pulmonary valve stenosis · valvular in 25% of the cases, · infundibular in 25%, A fibromuscular or fibrous hypertrophy of the infundibular region can be seen in the infundibular stenosis. · both valvular and infundibular in 50% of the cases.

We analyzed the indications for targeted sono-graphy, the abnormalities seen in various sonographic views, the postnatal echocardiographic and angiographic findings and autopsy findings.

Mar 4, 2010 · To describe a new ultrasonographic marker, the ‘question-mark’ sign, to assist in the diagnosis of tetralogy of Fallot (TOF) in the fetus, and to evaluate its prevalence in TOF as compared with other cardiac defects.

The fetal three vessel view (3VV) is useful for the diagnosis of Tetralogy of Fallot, and allows assessment of the superior vena cava, ascending aorta (AA), and main pulmonary artery (MPA) in that order.

Oct 21, 2024 · An ultrasound, a tool that creates pictures of the baby, may detect tetralogy of Fallot. If the health care provider suspects tetralogy of Fallot from the ultrasound, they can request a fetal echocardiogram confirming the diagnosis.

Tetralogy of Fallot may be diagnosed with fetal echocardiogram (ultrasound) before your baby is born. Our Fetal Heart Program will prepare a plan for delivery and care immediately after birth. Another common time for diagnosis of tetralogy of Fallot is after birth, but before your newborn leaves the hospital.

The four parts of tetralogy of Fallot (TOF) are: Pulmonary Stenosis, Ventricular Septal Defect (VSD), Overriding Aorta, and Right Ventricle Hypertrophy. It occurs in about 1 in 2500 to 1 in 3000 births.

Mar 1, 2019 · Tetralogy of Fallot (TOF) is a congenital heart defect (CHD) found in 1 of 3600 live births and represents 3.5% to 7% of all CHD's in infants. TOF is characterised by a ventricular septal defect (VSD), overriding aorta astride of the VSD and pulmonary stenosis or atresia with or without right ventricular hypertrophy.

The objective of this report was to emphasize the sonographic findings of tetralogy of Fallot (TOF) during the prenatal period. Four fetuses with TOF were prenatally diagnosed at gestational ages of 25, 28, 25, and 32 weeks.
