Saphenous vein grafting for angina

Area of Science:

• Cardiovascular Surgery
• Cardiac Surgery Outcomes
• Coronary Artery Bypass Grafting

Background:

• Saphenous-vein bypass grafting is a common treatment for coronary artery disease.
• Identifying preoperative factors predicting complications is crucial for patient management.

Purpose of the Study:

• To analyze outcomes and complications in patients undergoing saphenous-vein bypass grafting.
• To identify preoperative predictors of postoperative complications.
• To evaluate the impact of myocardial protection strategies on outcomes.

Main Methods:

• Retrospective analysis of 200 consecutive patients undergoing saphenous-vein bypass grafting.
• Assessment of preoperative factors including unstable angina, multivessel disease, and left ventricular function.
• Evaluation of postoperative complications such as infarction, low cardiac output, and arrhythmia.
• Comparison of outcomes with and without cardioplegic myocardial protection.

Main Results:

• Overall in-hospital mortality was low (1%).
• Unstable angina, multivessel disease, and impaired left ventricular function were associated with higher complication rates.
• Cardioplegic myocardial protection reduced complications in patients with impaired left ventricular function.
• Early follow-up showed 96% of patients were angina-free or virtually angina-free.
• Three patients experienced infarction within nine months post-surgery.

Conclusions:

• Saphenous-vein bypass grafting is effective in relieving angina.
• Preoperative risk stratification is essential for managing potential complications.
• Cardioplegic myocardial protection offers benefits, particularly for high-risk patients.
