Tetralogy Of Fallot With Absent Pulmonary Valve Syndrome Radiology Key

Tetralogy Of Fallot With Absent Pulmonary Valve Syndrome Radiology Key Anatomy and anatomical associations. tetralogy of fallot with absent pulmonary valve syndrome (tof apvs) is a rare variant of tetralogy of fallot (tof) in which the pulmonary valve leaflets are extremely underdeveloped resulting in severe pulmonary insufficiency and aneurysmal dilation of the main and branch pulmonary arteries. The etiology is multifactorial. tof has been associated with untreated maternal diabetes, phenylketonuria, and intake of retinoic acid. chromosomal anomalies occur in 30% of cases and include trisomies 21, 18, and 13 and 22q11 microdeletion, especially in pulmonary atresia and absent pulmonary valve syndrome (apvs, 40% to 50% of cases).

Tetralogy Of Fallot With Absent Pulmonary Valve Syndrome Radiology Key Diagnosis. tetralogy of fallot with absent pulmonary valve syndrome. a contrast enhanced ct image ( fig. 51b) shows markedly dilated main, right, and left pulmonary arteries in the mediastinum. the left main bronchus is compressed between the dilated pulmonary artery and the spine. the right main bronchus also shows a lesser degree of compression. The absent pulmonary valve syndrome (apvs) occurs in 3–6 % of patients with tetralogy of fallot (tof). apvs can also occur in isolation, with an intact ventricular septum (ivs), or it may occur in conjunction with other cardiac anomalies such as major aortopulmonary collateral arteries (mapcas), atrioventricular septal defect, double outlet. Tetralogy of fallot with absent pulmonary valve (tof apv) is a rare congenital heart defect associated with severe perinatal morbidity and mortality, with a reported survival after initial diagnosis of 14% to 68%. 1, 2, 3 the clinical presentation is highly variable. patients may have perinatal demise, may present with severe postnatal. Abstract. tetralogy of fallot with absent pulmonary valve syndrome is a rare variant of tetralogy of fallot marked by severe pulmonary insufficiency in utero and significant, sometimes massive, dilation of the pulmonary arteries. this syndrome can be associated with airway abnormalities that can cause respiratory compromise.

Absent pulmonary valve syndrome (apvs) is a rare congenital anomaly, usually seen in association with a ventricular septal defect. it has been reported to occur in 3–6% of cases of tetralogy of fallot (tof). in this case report we discuss a case. Absent pulmonary valve syndrome is a relatively rare condition, representing a subset of about 3% of cases of tetralogy of fallot in both autopsy and clinical reviews (1). the syndrome is characterized by a ringlike and usually stenotic malformation rather than by the absence of the pulmonary valve, with failure of development of the valve.
