Transapical minimally invasive aortic valve implantation; the initial 50 patients☆
Key result
Transapical minimally invasive aortic valve implantation was successfully performed in 94% of high-risk patients with aortic stenosis, with an actuarial survival of 71.4% at 1 year.
Why the study?
Is transapical minimally invasive aortic valve implantation feasible and safe in high-risk patients with aortic stenosis?
Population
50 high-risk patients with aortic stenosis, mean age 82.4+/-5 years, 78% female, average EuroSCORE predicted…

Implication
Supports feasibility in early high-risk series; leaves open need for randomized comparisons before wider adoption.

Population
50 high-risk patients with aortic stenosis (mean age 82.4 years, 78% female) undergoing transapical minimally invasive aortic valve implantation, followed for up to 1 year.
E
Exposure
Transapical minimally invasive aortic valve implantation (TAP-AVI) using a balloon expandable transcatheter xenograft (Edwards SAPIEN THV) via a small anterolateral minithoracotomy.

Transapical minimally invasive aortic valve implantation is feasible and yields acceptable 1-year survival in high-risk patients with aortic stenosis.
Cite This Study
Walther et al. (2008) conducted an observational in aortic stenosis (n=50). Transapical minimally invasive aortic valve implantation (TAP-AVI) was evaluated on Feasibility (successful implantation). Transapical minimally invasive aortic valve implantation was successfully performed in 94% of high-risk patients with aortic stenosis, with an actuarial survival of 71.4% at 1 year.
