[Reoperations after surgical correction of tetralogy of Fallot].
Between 1970 and 1981, 40 patients (6%) were reoperated after surgical correction of Fallot's tetralogy. The average age of these patients was 7,5 years (range 2 months to 37 years). The usual anatomical form was present in 30 cases and severe forms accounted for the other 10 cases (pulmonary atresia with septal defect were excluded). The 40 patients were divided into 3 groups according to the anatomical lesions corrected at reoperation: Group I: 16 patients with a residual isolated VSD; Group II: 14 patients with one or two residual right heart anomalies (RRHA) but without a septal defect; Group III: 10 patients with a residual VSD and RRHA. The only clinical difference between the patients of these 3 groups was the delay of onset of symptoms: the patients with residual VSD (Groups I and III) often developed cardiac failure immediately, whilst in those without residual VSD (Group II) cardiac failure was usually observed secondarily. Four patients (10%) died early after reoperation (less than 1 month). Three others died later, two during a third operation. The total mortality was similar in the three groups. The surgical result was assessed clinically after an average follow-up of 4,5 +/- 3 years: patients with a residual isolated VSD (Group I) had the best long-term results. In 12 patients, M mode and 2D echocardiography showed normal left ventricular function but the ratio of end diastolic right ventricular and left ventricular dimensions was increased to an average of 0,72 +/- 0,2.(ABSTRACT TRUNCATED AT 250 WORDS)
