Hypothesis

Does coronary surgery with cardiopulmonary bypass differ in effectiveness and safety compared to off-pump surgery in patients with multivessel coronary disease?

Conclusion

The MASS III Trial aims to determine the differences in medical effectiveness, safety, and quality of life between on-pump and off-pump coronary surgery.

Supporting Evidence

  • Off-pump surgery has been used since 1967 but gained popularity in the 1990s.
  • Randomized trials show small differences in outcomes between off-pump and on-pump surgery.
  • Long-term follow-up studies indicate potential inferior outcomes for off-pump surgery.

Takeaway

This study is looking at two ways to do heart surgery to see which one is better for patients with blocked arteries.

Methodology

A single-center, prospective, randomized clinical trial comparing on-pump and off-pump coronary surgery.

Potential Biases

Potential selection bias due to the single-center design and surgeon preference for surgical technique.

Limitations

The study is limited to a single institution, which may affect the generalizability of the results.

Participant Demographics

Patients with stable angina and multivessel coronary artery disease, aged 18 and older.
