Definition of tetralogy of Fallot in English:

tetralogy of Fallot


  • A congenital heart condition involving four abnormalities occurring together, including a defective septum between the ventricles and narrowing of the pulmonary artery, and accompanied by cyanosis.

    • ‘Hypertension is an obvious risk factor in our patient, and corrected tetralogy of Fallot can be considered as valvular disease.’
    • ‘Pulmonary valvuloplasty can also alleviate cyanotic spells in patients with tetralogy of Fallot whose pulmonary arteries are not yet large enough to undergo primary repair safely.’
    • ‘Right atrial enlargement is associated with chronic obstructive pulmonary disease, pulmonary hypertension, and congenital heart disease for example, pulmonary stenosis and tetralogy of Fallot.’
    • ‘High risk is conferred by certain complex cyanotic congenital heart diseases, such as transposition of the great arteries and tetralogy of Fallot.’
    • ‘Haemoptysis is a potentially lethal complication in adults who have been operated on for congenital heart disease, especially tetralogy of Fallot with pulmonary atresia with ventricular septal defect.’
