Radical surgical cure of Wolff-Parkinson-White syndrome: the Kanazawa experience.

Between 1973 and 1983, we operated on 160 patients with Wolff-Parkinson-White syndrome at Kanazawa University Hospital; 126 had Wolff-Parkinson-White syndrome alone, and 34 had combined cardiac diseases. Of the 160 patients, 140 were completely cured; postoperatively, they had no delta wave on electrocardiograms and no tachycardia attacks. In 11 patients, the delta wave reappeared an average of 56 days after operation. They, and three other patients with concealed Wolff-Parkinson-White syndrome, experienced several postoperative episodes of tachycardia. However, in 12 of the 14 patients with postoperative tachycardia attacks, these disappeared completely in the course of a long follow-up period and these patients are also considered to be cured symptomatically. In the two remaining patients, the tachycardia attacks persisted. Of the 126 patients with Wolff-Parkinson-White syndrome alone, none died as a direct result of the operation. Patients with combined cardiac diseases other than cardiomyopathy, mild Ebstein's anomaly, or venous abnormality were treated in one operation. Six of the 34 patients with combined cardiac diseases died. In none of the 160 patients was the His bundle intentionally interrupted as an alternative method of interrupting the accessory conduction pathway. Our study showed that life-threatening arrhythmias occur more often than expected in patients with Wolff-Parkinson-White syndrome and the tolerance for tachycardia attacks differs from patient to patient. Because the surgical treatment of Wolff-Parkinson-White syndrome is safe and reliable, as indicated in this report, the radical correction of this disease should be considered in carefully evaluated patients.

Effect of feed restriction on the peripheral blood and bone marrow cell counts of Wistar rats.

The effects of 33% and 66% restricted feeding on body and organ weights, and hematological and bone marrow cellular findings in rats were investigated. The body weight gains were suppressed by restriction of feed amount and the body weights of 66% restricted-feeding groups were almost unchanged for three months (110 g in males and 80 g in females). Marked organ weight reduction (both absolute and relative) was found in the liver and thymus of rats of both sexes. Neutrophils and lymphocytes in the peripheral blood were reduced. Reticulocytes in the 66% restricted groups were decreased to 1/4 of the control values at one month, but recovered slightly thereafter. Nucleated cell counts in bone marrow in the 66% restricted groups were decreased to 1/3 of the control values after three months. Thus, the most important effect of feed restriction seemed to be on bone marrow cells rather than on peripheral blood cells except for the reticulocytes. There was no significant difference between males and females.

Successful surgical ablation of reentrant ventricular tachycardia caused by myocardial fibroma.

We successfully removed a fibroma of the left ventricle in a 13-year-old boy. The tumor had caused recurrent ventricular tachycardia, which was resistant to antiarrhythmic drugs. Preoperative and intraoperative electrophysiological studies led to a diagnosis of reentrant ventricular tachycardia. After surgical excision of the tumor, the ventricular tachycardia stopped completely and until now, 1 year after the operation, no antiarrhythmic drugs have been required.
