GENERAL CARDIOLOGY
Transapical beating heart aortic valve implantation (TAP-AVI) has recently shown promise as a minimally invasive method of treating aortic stenosis in patients who are considered too high-risk for surgery. Walther et al analysed the results of the initial 50 patients receiving TAP-AVI at their centre in Leipzig, Germany.
Of the 50 patients, 47 (94%) successfully underwent TAP-AVI using rapid ventricular pacing. No complications such as embolisation or migration of the valve prosthesis occurred, but three patients required conversion to open surgery, one of whom died on day 125 owing to complications of a comorbid illness. Actuarial survival at 1 month, 6 months and 1 year was 92%, 73.9% and 71.4%, respectively.
These results are encouraging given the recent publication of a US study which found a much lower survival rate of 81.8% at 1 month, leading some to suggest that TAP-AVI is potentially not as safe as transfemoral aortic valve
