[Off-pump coronary artery bypass grafting for single coronary artery; report of a case]
1Department of Cardiovascular Surgery, Sanin Rosai Hospital, Yonago, Japan.
Insights
A rare coronary artery anomaly presented as angina pectoris. Surgical bypass grafting successfully treated the condition, restoring normal blood flow.
Area of Science:
- Cardiovascular Surgery
- Interventional Cardiology
- Anatomical Variations
Background:
- A 55-year-old male presented with angina pectoris due to a single coronary artery anomaly.
- Standard coronary arteriography failed to identify the left coronary orifice, necessitating detailed anatomical assessment.
Observation:
- Right coronary arteriography revealed an unusual coronary artery anatomy.
- The circumflex branch (Cx) coursed as the right coronary artery (RCA), and the left anterior descending (LAD) followed the Cx.
- Significant 90% stenosis was noted in the posterior descending branch (#4PD) of the RCA.
Findings:
- Off-pump coronary artery bypass grafting (CABG) was successfully performed.
- The D1 artery was bypassed using a left internal thoracic artery graft.
- The #4PD artery was revascularized with a radial artery graft.
Implications:
- This case highlights the importance of thorough coronary imaging in complex anatomical variations.
- Successful off-pump CABG demonstrates the feasibility of surgical intervention in anomalous coronary arteries.
- Effective revascularization strategies can alleviate symptoms and improve outcomes for patients with rare coronary anomalies.
Abstract:
A 55-year-old male with single coronary artery complicated by angina pectoris was referred to our department for coronary artery bypass grafting (CABG) . Coronary arteriography could not identify the left coronary orifice. Right coronary arteriography showed that the circumflex branch (Cx) followed the course of the normal right coronary artery (RCA) , and the left anterior descending branch (LAD) followed the Cx. Other findings included 90% stenosis in #4 posterior descending (PD) of RCA. Off-pump CABG was successfully performed to D1 with the left internal thoracic artery graft and to #4PD with the radial artery graft.
