Transapical aortic valve implantation in patients requiring redo surgery☆
Key result
Transapical aortic valve implantation in high-risk patients requiring redo surgery achieved a 96% procedural success rate and an 88% 30-day survival rate with no new-onset neurological events.
Why the study?
Does transapical aortic valve implantation provide safe and effective outcomes in high-risk patients with symptomatic aortic valve stenosis requiring redo cardiac surgery?
Population
25 high-risk patients with symptomatic aortic valve stenosis and previous cardiac surgical interventions…

Implication
Should not yet change practice in high-risk redo cases; leaves open need for prospective confirmation.

Type
Observational (n=25)
Structured PICO
Does transapical aortic valve implantation provide safe and effective outcomes in high-risk patients with symptomatic aortic valve stenosis requiring redo cardiac surgery?
P
Population
25 high-risk patients (mean age 78 years, 60% female) with symptomatic aortic valve stenosis and previous cardiac surgery, followed for up to 1 year.
E
Exposure
Transapical aortic valve implantation (TA-AVI) using a pericardial xenograft fixed within a stainless steel, balloon-expandable stent (Edwards SAPIEN).
O
Outcome
Procedural success and survival (30-day and one-year)hard clinical
Transapical aortic valve implantation is a feasible and effective alternative to conventional surgery with minimal stroke risk for elderly, high-risk patients requiring redo cardiac procedures.
Cite This Study
Walther et al. (2009) conducted an observational in Symptomatic aortic valve stenosis requiring redo surgery (n=25). Transapical aortic valve implantation (TA-AVI) was evaluated on 30-day survival. Transapical aortic valve implantation in high-risk patients requiring redo surgery achieved a 96% procedural success rate and an 88% 30-day survival rate with no new-onset neurological events.
