[Cardiac arrhythmia following total correction of tetralogy of Fallot].

41 patients after surgical correction of the tetralogy of Fall of aged 2-24 years (mean 11.2 y.) were followed for 12-65 months (mean 39.5 m.) for known or suspected dysrhythmias. 24-hour ambulatory ECG and exercise testing demonstrated nonsignificant ventricular ectopy (grade 0-1 according to a modified Lown classification) in 28 patients (group I) and significant (grade 2-5) ventricular dysrhythmias in the remaining 13 patients (group II). There were 2 cases of sudden late death in group II, whereas all patients in group I are alive. The victims of sudden death had no, other serious dysrhythmias and received no antiarrhythmic treatment. Ejection fraction of the functional part of the right ventricle estimated by radionuclide angiocardiography was not different in both groups whereas, global right ventricular ejection fraction differed nearly significantly (group I: 39.6 +/- 8.3%, group II: 31.9 +/- 10.4%, p = 0.052). Thus, a diminished global right ventricular ejection fraction caused by an extensive resection and large patch in the right ventricular outflow tract may be connected with the occurrence of higher grades of ventricular ectopy. These may lead to sudden late death.

Correction of aortico-left ventricular tunnel during the first day of life.

Two critically ill newborns with aortico-left ventricular tunnel and severe heart failure were operated on at six and 14 hours after birth. The diagnosis was established clinically by the auscultatory finding of systolic and diastolic murmurs and by two-dimensional and Doppler echocardiography. In the first newborn, the left aortic sinus was connected with the left ventricle below the aortic valve by an aneurysmatically dilated tunnel. In the second patient, the tunnel connected the right aortic sinus and the left ventricle. The repair was performed under deep hypothermia, total hemodilution, and cardiopulmonary bypass. The tunnel was closed with two patches of Gore-Tex on the aortic and ventricular orifices. Both children are free from symptoms and are developing normally 10 and 8 months after repair.

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.
