[CABG after patch angioplasty of the left main coronary: artery report of a case]
1Department of Cardiovascular Surgery, Kyoto Second Red Cross Hospital, Japan.
Insights
Recurrent left main coronary trunk restenosis after patch angioplasty led to successful coronary artery bypass grafting. This case highlights the need for careful consideration of patch angioplasty indications for left main coronary trunk lesions.
Area of Science:
- Cardiovascular Surgery
- Interventional Cardiology
- Vascular Medicine
Background:
- Patch angioplasty for left main coronary trunk (LMT) lesions can be complex.
- Restenosis remains a significant concern following LMT interventions.
Observation:
- A 57-year-old male presented with severe LMT restenosis after prior patch angioplasty.
- Multiple percutaneous transluminal coronary angioplasty (PTCA) procedures failed to resolve the restenosis.
- Coronary angiography confirmed 75% LMT restenosis despite previous interventions.
Findings:
- Surgical revascularization via double coronary artery bypass grafting (CABG) was performed.
- The LMT lesions were addressed using the left internal thoracic artery and a saphenous vein graft.
- Postoperative angiography demonstrated excellent graft patency and restoration of blood flow.
Implications:
- This case underscores the potential for restenosis after LMT patch angioplasty.
- Coronary artery bypass grafting may be a more durable solution for complex LMT lesions.
- Careful patient selection and consideration of alternative treatment strategies are crucial for LMT interventions.
Abstract:
A 57-year-old man was admitted to our hospital because of restenosis of the left main coronary trunk (LMT) after patch angioplasty for the LMT lesion. PTCA was repeated four times during three years after patch angioplasty, but recent coronary angiogram still demonstrated 75% restenosis of the LMT lesion. Double-CABG was performed to LAD and LCX using the left internal thoracic artery and saphenous vein graft. Postoperative coronary angiogram revealed an excellent result. A careful consideration must be given to the indication of the patch angioplasty of the LMT lesion.
