Reverse Wenckebach Phenomenon After Surgical Repair of Bicuspid Aortic Valve: Long-Term Follow-Up.

ABSTRACT:

Background

The Wenckebach phenomenon of atrioventricular conduction is deemed a physiological response of the atrioventricular node to a high atrial rate. However, the reverse Wenckebach phenomenon is under-recognized.

Case summary

We report an instance of reverse Wenckebach phenomenon developing into complete heart block in a 33-year-old man who experienced syncope after surgical repair of prolapsed bicuspid aortic valves. His condition was managed by temporary pacing. However, long-term follow-up demonstrated that the reverse Wenckebach phenomenon and severe heart block was reversible, avoiding the need for a permanent pacemaker.

Discussion

Reverse Wenckebach phenomenon can occur spontaneously and degenerate to complete heart block. Combined with our findings, early
