Racemose bronchial artery malformation with coronary artery inflow is rare. A staged hybrid approach involving embolization and minimally invasive surgery successfully treated a patient with mitral and tricuspid regurgitation.
Area of Science:
- Cardiovascular Surgery
- Vascular Malformations
- Interventional Cardiology
Background:
- Racemose hemangioma of the bronchial artery is a rare vascular malformation.
- Abnormal communication between bronchial and pulmonary vasculature can occur.
- Coronary arterial inflow complicates cardiac surgery by impairing myocardial protection.
Purpose of the Study:
- To report a case of racemose bronchial artery malformation with coronary arterial inflow.
- To describe the management of associated atrial functional mitral and tricuspid regurgitation.
- To evaluate the effectiveness of a staged hybrid strategy.
Main Methods:
- Preoperative embolization of systemic feeders from bronchial and left subclavian arteries.
- Minimally invasive valve repair.
- Surgical ligation of the coronary inflow vessel.
Main Results:
- Successful treatment of racemose bronchial artery malformation with coronary arterial inflow.
- Resolution of atrial functional mitral and tricuspid regurgitation.
- Uneventful postoperative course.
Conclusions:
- A staged hybrid strategy combining embolization and minimally invasive cardiac surgery is effective.
- This approach can successfully manage racemose bronchial artery malformation with coronary arterial inflow and associated valve regurgitation.
