tetralogy of Fal·lot

A congenital malformation of the heart characterized by a defect in the ventricular septum, misplacement of the origin of the aorta, narrowing of the pulmonary artery, and enlargement of the right ventricle.

[After Étienne Fallot (1850-1911), French physician.]
ThesaurusAntonymsRelated WordsSynonymsLegend:
Noun1.tetralogy of Fallot - a congenital heart defect producing cyanosis; characterized by four symptoms: pulmonary stenosis and ventricular septal defect and malposition of the aorta over both ventricles and hypertrophy of the right ventricle
pulmonary stenosis - abnormal narrowing of the opening into the pulmonary artery from the right ventricle
syndrome - a pattern of symptoms indicative of some disease
congenital heart defect - a birth defect involving the heart
ventricular septal defect - a common congenital heart defect; an abnormal opening in the septum dividing the ventricles allows blood to pass directly from the left to the right ventricle; large openings may cause congestive heart failure

Absent pulmonary valve syndrome along with TOF was diagnosed in 2 (0.
In developing countries like Pakistan, diagnosis of TOF is often delayed because of limited number of pediatric cardiology and pediatric cardiac surgery departments.
Fibreoptic bronchoscopy (FOB) revealed a TOF (3 cm long and 1 cm wide) in the right posterolateral tracheal wall, situated distal to the equator of the cuff and extending almost to the tip of the TT (Fig.
5,8,11) Hence, the present study to detect the extent of residual neuromuscular paralysis by TOF ratio with intermediate acting muscle relaxants at time of tracheal extubation.
The TOF measurement is associated with the energy, amplitude, or centroid of the signal.
Thus the fundamental asymmetry will have the same, well understood, parametric dependence on TOF and can be extracted by a fit to the asymmetry data.
These TOF innovations enable automated sub-ppm mass accuracy and a wide dynamic range with internal reference mass (IRM) correction for all ion sources in a thermally stable TOF design.
The neutron decay rate is and ~[1 + a [beta] cos(Vev)] and (1/[beta])(d ln(Y)/da) approaches [+ or -]1 for small and large values of TOF, where cos(Vev) = [+ or -]1, as expected.
The ion trap is then used as a pusher for the TOF analysis.
To independently verify the custom software's calculations, TOF values and final positions were compared to SIMION results calculated from the same initial conditions and electric and magnetic fields.
