Insights
Coronary artery fistulae developed in a heart transplant patient after biopsies. These rare vascular abnormalities draining into the right ventricle showed a small shunt magnitude over eight years.
Area of Science:
- Cardiology
- Transplantation Medicine
- Vascular Surgery
Background:
- Cardiac transplant recipients undergo frequent monitoring, including invasive procedures.
- Endomyocardial biopsies are standard for assessing graft health but carry potential risks.
- Coronary artery fistulae are abnormal connections between coronary arteries and heart chambers or vessels.
Observation:
- A case study identified multiple coronary artery fistulae in a cardiac transplant recipient.
- These fistulae were presumed to arise secondary to repeated endomyocardial biopsy procedures.
- The fistulae were observed to drain directly into the right ventricle.
Findings:
- Diagnosis of coronary artery fistulae was confirmed via annual coronary arteriography.
- The shunt magnitude through the fistulae remained consistently small throughout an eight-year follow-up period.
- This suggests a potentially benign clinical course for biopsy-induced fistulae in select cases.
Implications:
- Highlights a rare complication of endomyocardial biopsies in heart transplant patients.
- Underscores the importance of vigilant surveillance for vascular anomalies post-transplant.
- Suggests that small-magnitude coronary artery fistulae may not necessitate immediate intervention.
Abstract:
A cardiac transplant recipient with multiple coronary artery fistulae draining into the right ventricle is described. These fistulae presumably resulted from repeated endomyocardial biopsies. The diagnosis of coronary artery fistulae was made at the annual coronary arteriography. The magnitude of the shunt remained small over eight years of follow-up.
