Insights
A 56-year-old woman with mitral stenosis and a left atrial clot underwent surgery. A novel methylene blue dye technique successfully closed a coronary fistula during the procedure, ensuring a smooth recovery.
Area of Science:
- Cardiology
- Cardiac Surgery
Background:
- Rheumatic mitral stenosis is a significant valvular heart disease.
- Left atrial clots pose a risk of systemic embolism.
- Coronary cameral fistulas are rare congenital or acquired abnormalities.
Observation:
- A 56-year-old female patient presented with rheumatic mitral stenosis and a left atrial clot.
- Coronary angiography revealed a fistula between the posterior left ventricular branch and the left ventricle.
- The presence of a coronary fistula alongside mitral valve disease and a clot is uncommon.
Findings:
- Surgical mitral valve replacement and clot removal were performed.
- A methylene blue dye injection technique was utilized intraoperatively.
- This technique facilitated the safe detection and closure of the coronary fistula from within the left ventricle.
Implications:
- Safe closure of coronary fistulas is crucial to prevent complications like infective endocarditis, particularly with prosthetic valves.
- Methylene blue dye injection offers a simple and effective method for intraoperative fistula management.
- This approach ensures a favorable outcome in complex cardiac cases involving combined pathologies.
Abstract:
A 56-year-old female presented to us with rheumatic mitral stenosis with a left atrial clot. We found one coronary cameral fistula on the coronary angiography from the posterior left ventricular branch to the left ventricle. She was taken up for surgical mitral valve replacement and clot removal. A residual coronary fistula may increase the risk of infective endocarditis, especially in the presence of mechanical prosthesis. Henceforth, intra-operatively, we used the methylene blue dye injection as an easy technique to detect and safely close the coronary fistula from inside the left ventricular chamber. She recovered smoothly with a successful outcome.
