Surgical treatment of supraventricular tachyarrhythmias
WC Sealy, RW Anderson and JJ Gallagher
In this report, we have outlined our experiences with the direct surgical
treatment of 16 patients with supraventricular tachyarrhythmias (SVTA).
Re-entry supraventricular tachycardia (SVT) was demonstrated by the 4
patients who had retrograde-conducting Kent pathways. The SVT was corrected
by the successful division of the Kent bundle in 3 and a partially
successful His bundle division in one patient. The remaining 9 patients
with re-entry, which included 6 with Kent pathways and WPW, all had His
bundle section. The remaining 3 with His interruption had focal
tachycardias associated with dysfunction of the atrioventricular (AV) node.
Of the 13 His bundle interruptions, nine were successful, three resulted in
questionable AV conduction, and one failed. Problems with suture ligation
and cautery explained the failures. Cryothermia was the most successful
procedure used. However, excision of that portion of the atrium containing
the AV node shows promise of being satisfactory. The possibility is
discussed of using measures much more precise and less destructive than His
bundle interruption for SVTA.
