Overview

Supports early feasibility of transapical beating-heart implantation; leaves open need for larger studies to assess mortality.

Structured PICO

P
Population
30 consecutive high-risk patients with aortic stenosis, mean age 82 +/- 5.1 years, 70% female. Average EuroSCORE predicted risk for mortality was 27 +/- 12%.
I
Intervention
Minimally invasive transapical beating heart aortic valve implantation (TAP-AVI) via a small anterolateral minithoracotomy with or without femoral extracorporeal circulation (ECC) using a pericardial xenograft fixed within a stainless steel, balloon expandable stent.
O
Outcome
Feasibility of minimally invasive transapical beating heart aortic valve implantation (TAP-AVI)

Minimally invasive transapical beating heart aortic valve implantation is a feasible proof-of-concept approach for high-risk patients with aortic stenosis.

Limitations

  • Requires long-term studies
  • Requires randomized protocols
