“…The procedural success rate was high. Compared to a control group of patients who underwent conventional AVR (by propensity score analysis), 30-day and one-year survival superior for trans-apical TAVI, but this difference was not significant (97).…”

“…A recent systematic review (Figulla et al, 2011) incorporating pooled data from multiple studies reported that mean one-year survival after TAVI was 75.9% (range: 64.1% to 87.0%) (Al-Attar et al, 2009;Grube et al, 2008;Himbert et al, 2009;Kapadia et al, 2009;Otten et al, 2009;Rajani et al, 2010;Rodes-Cabau et al, 2010;Thielmann et al, 2009;Walther et al, 2010;Webb et al, 2009a;Ye et al, 2009). In contrast the mean one-year survival rate for patients treated with medical care alone was 62.4% (range: 40.0% to 84.8%; p < 0.01 vs. TAVI), revealing a 13.5% survival advantage in favor of TAVI at one year.…”

“…Transcatheter aortic valve implantation (T-AVI) was first described by Cribier in 2002 [1] and since then has evolved as a routine procedure for high risk patients with aortic stenosis [2,3]. As of June 2010, 10,000 transfemoral (TF) implants of the CoreValve TM prosthesis (Medtronic Inc., Minneapolis, MN, USA) and approximately a similar number of TF and transapical (TA) implants of the Edwards Sapien TM prosthesis (Edwards Lifesciences Inc., Irvine, CA, USA) ( Fig.…”

Transcatheter aortic valve implantation (T-AVI) has shown good results in high-risk patients with severe aortic stenosis. Throughout the whole process of T-AVI, different imaging modalities are indispensable. Preoperatively, multislice computed tomography, angiography and transesophageal echo (TEE) are utilized for patient selection, valve selection, approach selection and the planning of implant placement. Intraoperatively, angiography and TEE are used for controlling placement of the guidewire and valve positioning. Quality control and follow-up require TEE imaging and can require additional CT or angiography studies. In the first half of this paper, we discuss the applicability of different imaging modalities for T-AVI in the light of the current best practice. In the second half of this paper, we present an overview on research projects in medical engineering which aim at development of imagebased methods for increasing patient safety during T-AVI. Template-based implantation planning, as it is applied in dental, orthopedic and other surgical disciplines, is proposed as an aid during implant selection in order to help reduce the incidence of complications such as atrioventricular node block and paravalvular leaks. Current research tries to apply state-of-the-art engineering techniques, such as computational fluid dynamics to optimize valve selection and positioning. For intraoperative assistance during valve positioning, real-time image processing methods are proposed to track target landmarks and the stented valve.

Transapical aortic valve implantation in 100 consecutive patients: comparison to propensity-matched conventional aortic valve replacement

Abstract: Transapical aortic valve implantation is a safe, minimally invasive, and off-pump technique to treat high-risk patients with aortic stenosis. Results of the initial 100 patients are good and compare favourably to conventional surgery.
