Why the study?
Does minimally invasive AVR through a transverse sternotomy improve outcomes compared to median sternotomy in high-risk patients?
Does minimally invasive AVR through a transverse sternotomy improve outcomes compared to median sternotomy in high-risk patients?
Minimally invasive AVR through a transverse sternotomy in high-risk patients is associated with longer operative times and an unacceptably high incidence of morbidity and mortality compared to median sternotomy.
No takes yet. Share an insight, caveat, or question.
Minimally invasive transverse sternotomy AVR warrants caution in high-risk patients; leaves open whether randomized trials would confirm worse outcomes versus median sternotomy.
Bridgewater et al. (1998) studied this question.
