Summary
A patient with mitral regurgitation and sick sinus syndrome experienced pacemaker issues after surgery. Careful placement of the atrial lead is crucial for DDD pacemakers in patients undergoing the Maze procedure to prevent cross-stimulation.
Area of Science:
- Cardiology
- Cardiac Surgery
- Electrophysiology
Background:
- A 26-year-old male presented with mitral regurgitation and sick sinus syndrome, necessitating VVI pacemaker implantation.
- Post-implantation, the patient was hospitalized for congestive heart failure, prompting further cardiac evaluation.
Observation:
- Echocardiography and cineangiography confirmed severe mitral regurgitation.
- The patient subsequently underwent mitral valvuloplasty and a modified Maze procedure, followed by DDD pacemaker implantation.
Findings:
- Seven months post-operation, cross-stimulation was identified as a complication.
- The cross-stimulation was attributed to the low right atrial placement of the atrial lead.
Implications:
- This case highlights the importance of precise atrial lead positioning in DDD pacemakers.
- Careful implantation is recommended for patients who have undergone the Maze procedure to avoid lead-related complications like cross-stimulation.
