| pubmed-article:3573801 | pubmed:abstractText | One hundred fifty-six patients underwent investigation and operation for supraventricular tachycardia: 145 had attempts at curative operations and 11 had His bundle section. Operative mortality was 0.68% and there were no late deaths among patients having curative operations. One patient died suddenly 1 year after His bundle section. All patients underwent electrophysiologic study before discharge and 6 months postoperatively. A satisfactory result, without supraventricular tachycardia and without medication, was achieved in 96.5% of all patients. Ninety-three percent have no supraventricular tachycardia and no demonstrable reentrant pathway at electrophysiologic study. All free wall accessory atrioventricular connections were divided and 97.7% of the patients were cured. Ninety percent of patients with posterior septal accessory atrioventricular connections had a satisfactory result, with cure demonstrated at late electrophysiologic study in 84%. Fifteen patients with atrioventricular junctional reentrant tachycardia were all cured, with preservation of normal atrioventricular conduction. Eight (88%) of nine patients with right atrial tachycardia were cured, and two patients with nodoventricular fibers and one patient with incessant atrioventricular junctional tachycardia had satisfactory results. Supraventricular tachycardia is now a potentially curable disorder when managed by low risk surgical procedures that offer a high cure rate. | lld:pubmed |
