Summary
A rare left ventricular-right atrial fistula complicated redo mitral valve replacement, causing heart failure. Surgical closure with pericardium patch successfully resolved the fistula and heart failure symptoms.
Area of Science:
- Cardiology
- Cardiac Surgery
- Medical Case Reports
Background:
- Redo mitral valve replacement is a complex procedure.
- Postoperative heart failure can have various etiologies.
- Rare complications require thorough investigation and tailored management.
Observation:
- A 58-year-old female presented with persistent heart failure post-redo mitral valve replacement.
- Diagnostic workup revealed a left ventricular-right atrial fistula, a rare cardiac anomaly.
- The fistula was identified as the cause of refractory heart failure.
Findings:
- Surgical intervention was performed to close the left ventricular-right atrial fistula.
- An autologous pericardium patch was utilized for successful fistula closure.
- The patient experienced immediate and sustained improvement in heart failure symptoms post-surgery.
Implications:
- This case highlights the importance of considering rare fistulas in refractory heart failure after cardiac surgery.
- Autologous pericardium serves as a viable graft material for complex fistula repair.
- Successful surgical management of such fistulas can lead to excellent patient outcomes and symptom resolution.
