Why the study?
Does radical root replacement improve long-term event-free survival compared to conventional valve-preserving root reconstruction in patients with acute type A dissection?
Does radical root replacement improve long-term event-free survival compared to conventional valve-preserving root reconstruction in patients with acute type A dissection?
Radical root replacement in acute type A dissection yields excellent long-term event-free survival without increasing operative mortality, despite being performed in higher-risk patients.
No takes yet. Share an insight, caveat, or question.
Radical root replacement was associated with better event-free survival despite higher risk; extends observational data but leaves open need for randomized confirmation.
Ergin et al. (1996) studied this question.
