Figure 8. Post-operative imaging revealed successful repair of
the mitral valve and reduced mitral valve regurgitation.
After pacemaker extraction, an EP study was performed to determine
eligibility for another pacemaker insertion. However, studies showed
normal sinus node function (1,050 ms, CSNRT 200 ms), normal AV node
function (AH 95 ms), and mildly prolonged HV interval (65 ms). There is
no evidence of dual AV node physiology or accessory pathway. VA
conduction was present. The decision was thus made to not implant
another pacemaker. The patient is in general good health
post-operatively with no further dizziness or lightheadedness, and no
chronotropic incompetence.
