Hypothesis
What are the mid-term outcomes of atrioventricular valve repair in patients with functional single ventricle?
Conclusion
Atrioventricular valve repair can significantly improve valve function in patients with single ventricle and severe regurgitation, although some may have poor prognosis due to recurrent regurgitation.
Supporting Evidence
- Early mortality was 3.6% with one patient dying from low cardiac output syndrome.
- 78.5% of patients showed no more than mild regurgitation postoperatively.
- Mean follow-up time was 5.4 years, with a long-term mortality rate of 11.1%.
Takeaway
Doctors fixed heart valves in kids with a special heart condition, and most of them got better, but some still had problems later.
Methodology
A retrospective study of 28 patients who underwent atrioventricular valve repair surgery between April 2007 and October 2022.
Limitations
The study is retrospective and from a single institution, which may limit the generalizability of the findings.
Participant Demographics
The cohort included 21 males and 7 females, with a mean age of 8.7 years.
