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.
