Hypothesis
What is the prognostic value of less than moderate residual mitral regurgitation for early outcomes after mitral valve repair?
Conclusion
Patients with less than moderate residual mitral regurgitation had a trend toward a higher risk of early adverse outcomes compared to those with no residual mitral regurgitation.
Supporting Evidence
- The primary endpoint occurred in 5.5% of patients with no residual MR and 13.6% with less than moderate MR.
- There was a trend toward longer hospital stays among patients with less than moderate residual MR.
- 72% of patients presented with NYHA 3/4 classification.
Takeaway
This study looked at patients who had heart surgery to fix a valve. It found that those with a little bit of leftover leaking after the surgery might have more problems than those with no leaks at all.
Methodology
Retrospective analysis of patients undergoing isolated mitral valve repair with less than moderate residual mitral regurgitation.
Potential Biases
Potential selection bias due to exclusion criteria.
Limitations
The study had a small sample size and lacked long-term follow-up data.
Participant Demographics
72% of patients had NYHA 3/4 classification; 38% were women.
