Insights
Coronary artery bypass grafting successfully treated a patient with a rare single coronary artery. The surgical intervention relieved symptoms and confirmed successful graft patency, offering a viable treatment option.
Area of Science:
- Cardiovascular Surgery
- Interventional Cardiology
- Congenital Heart Anomalies
Background:
- Single coronary artery is a rare congenital anomaly.
- Atherosclerotic disease in single coronary artery poses unique surgical challenges.
- Management strategies for single coronary artery disease require careful consideration.
Observation:
- A 61-year-old male presented with chest pain and palpitations.
- ECG indicated ischemic changes, and elevated CPK levels confirmed myocardial injury.
- Coronary angiography identified a Type L II A single coronary artery with multi-vessel stenosis.
Findings:
- Successful Coronary Artery Bypass Grafting (CABG) was performed.
- Left Internal Thoracic Artery (LITA) was used for the Left Anterior Descending (LAD) artery.
- Saphenous vein grafts were utilized for other stenosed branches.
- Postoperative angiography demonstrated patent grafts.
Implications:
- CABG is a feasible treatment for symptomatic single coronary artery disease.
- This case highlights the importance of accurate diagnosis and tailored surgical approaches.
- Successful revascularization can lead to symptom relief and improved outcomes in patients with this anomaly.
Abstract:
Coronary artery bypass grafting in a patient with a single coronary artery is reported. A 61-year-old male who had chest pain and palpitation was transferred to our hospital. His ECG showed ischemic change, and CPK rose to a high level. Emergency coronary angiography revealed a type L II A (Lipton's criteria) single coronary artery and atherosclerotic stenosis on three major branches. He underwent CABG of LAD using LITA, #3 and #14 using saphenous vein grafts. Post operative angiography confirmed patent grafts, and the patient was free from symptoms.
