Results of total repair of tetralogy of Fallot after previous subclaviopulmonary or aortopulmonary anastomosis.

Total repair of tetralogy of Fallot was performed in 69 patients after the primary construction of a Blalock (28 patients) or a Waterston (41 patients) anastomosis. A total of 7 patients (10.1%) died. One to 5 yrs after correction, 62 patients (89.9%) survive: 52 (75.4%) are in a very good condition, 7 (10.1%) are in a good condition and the condition of 3 (4.4%) is unsatisfactory. 8 (11.6%) patients have serious late complications. The result of correction is not much influenced by the previous Blalock anastomosis (mortality rate 6.9%). After the Waterston anastomosis, however, there are frequent serious complications (pulmonary hypertension in 25.0% of patients), which adversely affect the result and increase mortality (12.5%) of the subsequent correction. The authors prefer two-stage repair of tetralogy of Fallot in the first two years of life. By administration of beta-blockers and prostaglandins they endeavour to postpone the construction of a Blalock anastomosis or an anastomosis performed by means of a polytetrafluoroethylene vascular prosthesis up to the age when the pulmonary artery branches are at least 4 mm in diameter. They plan the subsequent correction to be performed between the 2nd and the 5th year of age.

Results of corrective surgery for tetralogy of Fallot.

During a 5-year period (1978-1983) corrective surgery for tetralogy of Fallot was performed in 114 patients, ranging in age from 2 to 24 years (mean 8.4 years). Forty-one of them (35.9%) had previously undergone a palliative operation. Insertion of a transannular patch was necessary in 48 patients (42.1%). Eleven children died in the immediate postoperative period (early mortality 9.6%); no deaths occurred later. 103 survivors were followed-up for periods ranging from 5 months to 5 years mean 2.4 years) after surgery. The condition in 91 patients was excellent (88.7%), in 11 good (10.7%) and in one poor. Residual ventricular septal defect persisted in 9 patients (8.7%). Postoperative ECG revealed complete right bundle branch block in 71 patients (59%), incomplete block in 18 (18%), 5 patients (5%) had complete RBBB with left anterior hemiblock. Postoperative dysrhythmia requiring treatment was found in 7 patients (6%). Of 82 patients thoroughly examined by echocardiography, 37 (45%) had pulmonary regurgitation, 29 (35%) pulmonary plus tricuspid regurgitation, and 3 (4%) isolated tricuspid regurgitation. 83% of the patients had impaired lung function.

Transient postnatal heart failure caused by noncompaction of the right ventricular myocardium.

Isolated noncompaction of the ventricular myocardium is a cardiomyopathy influencing almost exclusively the left ventricle in children and adults. We report a case of a neonate presenting with right ventricular failure caused by a noncompaction of the right ventricle. However, later course of the disease demonstrated biventricular involvement. Right ventricular noncompaction can be a cause of early postnatal right ventricular failure.
