Insights
Coronary ostial stenosis (COS) is a rare complication after Bentall-De Bono surgery. Advanced imaging and prompt revascularization are crucial for managing this condition and improving patient outcomes.
Area of Science:
- Cardiovascular Surgery
- Interventional Cardiology
- Medical Imaging
Background:
- Coronary ostial stenosis (COS) is a rare but serious complication following the Bentall-De Bono procedure.
- This case highlights a patient presenting with heart failure eight years post-Bentall-De Bono surgery and venous graft reconstruction.
Background:
Coronary ostial stenosis (COS) is a rare but potentially fatal complication following the Bentall-De Bono procedure.
Case Summary:
A 59-year-old man with prior Bentall-De Bono surgery along with venous graft reconstruction presented 8 years later with heart failure. Coronary computed tomography angiography demonstrated venous graft ostial stenosis, and cardiac magnetic resonance confirmed a transmural infarction with impaired ventricular function. Given the complex coronary anatomy and limitations to percutaneous treatment, the Heart Team opted for urgent surgical revascularization.
Discussion:
COS after aortic root replacement results from multifactorial mechanisms, including surgical trauma, excessive tension, kinking, or fibrosis related to adhesives, whereas venous graft stenosis adds further complexity. Diagnosis is often challenging because coronary angiography may underestimate the disease while coronary computed tomography angiography and cardiac magnetic resonance offer superior anatomical and functional assessments, enabling accurate detection and guiding timely revascularization.
Take-Home Messages:
COS represents an uncommon yet life-threatening complication of aortic root replacement. Advanced multimodal imaging is pivotal to precise diagnosis and therapeutic guidance. Prompt, tailored revascularization strategies are essential to improving clinical outcomes.
