A rare acquired Gerbode defect, a shunt between the left ventricle and right atrium, occurred after AV node ablation. This case highlights an unusual complication in patients with severe heart conditions.
Area of Science:
- Cardiology
- Cardiac Surgery
- Electrophysiology
Background:
- Gerbode defects, characterized by a left ventricular-to-right atrial shunt, are typically congenital.
- Acquired Gerbode defects are rare, with prior reports linked to endocarditis of the aortic or tricuspid valves.
Observation:
- A case of an acquired Gerbode defect is presented.
- The defect developed secondary to catheter ablation of the atrioventricular (AV) node.
Findings:
- The patient had a severely dilated cardiomyopathy and refractory atrial fibrillation.
- The Gerbode defect was a direct consequence of the AV node ablation procedure.
Implications:
- This case expands the known etiologies of acquired Gerbode defects.
- It underscores the potential for rare cardiac structural complications following electrophysiological procedures, even in the absence of endocarditis.
