Insights
This study details a successful simultaneous surgery for left atrial myxoma and coronary artery bypass grafting (CABG) in a 78-year-old woman. The myxoma resection preceded CABG to prevent embolism, ensuring a safe recovery.
Area of Science:
- Cardiovascular Surgery
- Cardiac Oncology
- Interventional Cardiology
Background:
- Left atrial myxoma is a rare primary cardiac tumor.
- Coronary artery bypass grafting (CABG) is a standard procedure for significant coronary artery disease.
- Concurrent myxoma resection and CABG presents unique surgical challenges.
Observation:
- A 78-year-old female patient presented with both left atrial myxoma and angina pectoris.
- The surgical strategy involved prioritizing myxoma resection before CABG.
- Antegrade and retrograde cardioplegia infusion was employed for myocardial protection.
Findings:
- The simultaneous surgical approach was successfully performed.
- Resection of the left atrial myxoma prior to CABG effectively mitigated the risk of systemic embolism.
- The patient experienced an uneventful recovery and was discharged in good condition.
Implications:
- This case highlights the feasibility and safety of combined myxoma resection and CABG.
- Strategic sequencing of procedures is crucial for optimizing patient outcomes in complex cardiac cases.
- Further research may explore optimal management strategies for patients with co-existing cardiac tumors and ischemic heart disease.
Abstract:
A 78-year-old woman who had been diagnosed as left atrial myxoma and angina pectoris underwent simultaneous coronary artery bypass grafting (CABG) and resection of the left atrial myxoma. CABG was preceded by resection of myxoma to avoid systemic embolism of fragment of myxoma. Myocardial protection was secured by combination of antegrade and retrograde infusion of cardioplegia. The patient recovered well and discharged uneventfully.
