Rotablation and stent placement in an unprotected left main coronary ostial stenosis
1St. Paul Heart Clinic, MN 55102, USA.
Insights
This case study highlights a successful percutaneous coronary intervention for unprotected left main stenosis after failed bypass grafts. Intracoronary ultrasound-guided atherectomy and stenting offer a viable option for complex coronary artery disease.
Area of Science:
- Cardiology
- Interventional Cardiology
Background:
- Unprotected left main (LM) coronary stenosis poses significant risks, especially after failed coronary artery bypass grafting (CABG).
- Rest angina and occluded coronary arteries necessitate advanced treatment strategies.
Observation:
- A patient with postinfarction rest angina and high-grade ostial LM stenosis experienced complete graft failure within two months post-CABG.
- Intracoronary ultrasound (ICUS) guided percutaneous coronary intervention (PCI) was employed for the unprotected LM lesion.
Findings:
- Rotablation followed by stent deployment resulted in successful angiographic outcomes without immediate complications.
- At one-year follow-up, the patient remained clinically stable with mild restenosis, indicating durable results.
Implications:
- ICUS-guided atherectomy and stenting represent a promising interventional approach for complex unprotected LM stenosis.
- This strategy may improve procedural success and long-term outcomes in high-risk cardiovascular patients.
Abstract:
We report the case of a patient with postinfarction rest angina, high grade ostial left main (LM) stenosis, and right and circumflex coronary occlusion. Coronary artery bypass was performed, yet all grafts failed within 2 months of surgery. We elected to proceed with coronary intervention on the ostial LM lesion with intracoronary ultrasound lesion characterization and percutaneous cardiopulmonary bypass support. Rotablation followed by stent deployment achieved a successful angiographic outcome with no associated clinical complications. At 1-year follow-up, the patient remains stable with evidence of mild restenosis. Interventional approaches in unprotected LM coronary stenoses are associated with high procedural risk. Combined atherectomy/ablation with stent placement guided by intracoronary ultrasound may enhance procedural and long-term outcome.
