United States Feasibility Study of Transcatheter Insertion of a Stented Aortic Valve by the Left Ventricular Apex

Transcatheter Versus Surgical Aortic Valve Replacement

“…replacement, 27,28,30,31,34 the rates of death at 30 days were higher among patients who had undergone transapical placement than among those who had undergone transfemoral placement. Possible reasons for these increased rates in the transapical cohort include an increased rate of coexisting disorders, a more protracted learning curve for surgeons, a smaller number of patients who were evaluated, and important procedural differences.…”

“…[22][23][24][25][26][27][28][29][30][31][32][33][34] In the randomized Placement of Aortic Transcatheter Valves (PARTNER) trial, a subgroup of patients with aortic stenosis who were not candidates for surgical aortic-valve replacement and who underwent transfemoral placement had an improvement of 20% in the 1-year survival rate and also had reduced symptoms. 35 This report describes results for the highrisk subgroup of patients in the PARTNER trial who were still candidates for surgical valve replacement and who were randomly assigned to undergo either transcatheter or surgical replacement of the aortic valve.…”

Transcatheter Aortic Valve Implantation

“…In another multicentre study by Walther et al, 55 out of 59 implants were deployed successfully with four patients requiring urgent sternotomy and AVR due to device malposition (Walther et al, 2007). In an article by Svensson et al (2008), procedural success was 88% in 40 patients undergoing transapical TAVI. Of the five patients in whom TAVI was deemed to have failed, the etiological factors were valve embolization (n = 3), valve migration (n = 1), and paravalvular leak (n = 1).…”

Implante transapical de endoprótese valvada balão-expansível em posição aórtica sem circulação extracorpórea

“…The transcateter aortic valve implantation is a new technique and under study in various centers around the world [4][5][6]. The main objective of the procedure is to provide a satisfactory technical quality with lower morbidity and mortality when compared to the conventional approach, especially by avoiding the use of cardiopulmonary bypass, median sternotomy and aortic clamping.…”
