Summary
Acquired coronary cardiac fistulas are rare, often resulting from thoracic trauma. This report details a unique case of a postoperative fistula involving the left ventricle, highlighting potential complications.
Area of Science:
- Cardiology
- Cardiac Surgery
- Vascular Medicine
Background:
- Acquired coronary cardiac fistulas are uncommon cardiovascular anomalies.
- Historically, reported cases (30) are predominantly secondary to thoracic trauma.
- The right cardiac chambers are the most frequently involved cardiac structures.
Observation:
- A continuous cardiac murmur is the most consistent clinical finding.
- Untreated fistulas can lead to coronary insufficiency and congestive heart failure.
- Surgical intervention has been the management strategy in the majority of reported cases (22/30).
Findings:
- This study presents a rare case of a postoperative coronary cardiac fistula.
- The fistula originated secondary to left ventricular venting.
- The fistula tract directly involved the left ventricular cavity, a unique anatomical presentation.
Implications:
- This case expands the known etiologies of acquired coronary fistulas beyond trauma.
- Understanding the specific mechanisms and anatomical involvements is crucial for surgical planning.
- Highlights the importance of considering iatrogenic causes for cardiac fistulas post-cardiac procedures.
