Feasibility of transcatheter aortic valve implantation in patients with coronary heights ≤7 mm: insights from the transcatheter aortic valve implantation Karlsruhe (TAVIK) registry.

Objectives: Transcatheter aortic valve implantation (TAVI) in patients with low coronary heights is generally denied but is not impossible. Information about these high-risk procedures is sparse.

Methods: Since May 2008, data of more than 3000 patients who had TAVI were prospectively collected in the institutional TAVI Karlsruhe registry.

A comparison of transcatheter aortic valve implantation and surgical aortic valve replacement in 1,141 patients with severe symptomatic aortic stenosis and less than high risk.

Objectives: To assess outcomes for patients undergoing transcatheter aortic valve implantation (TAVI) versus surgical aortic valve replacement but with less than high risk.

Background: While there is abundant data for high risk patients there is insufficient data for reduced risk.

Methods: Patients undergoing TAVI or SAVR between 2007 and 2012 in Karlsruhe were considered.

Long-term results of transapical versus transfemoral TAVI in a real world population of 1000 patients with severe symptomatic aortic stenosis.

Background: Transapical transcatheter aortic valve implantation is generally perceived to be associated with increased morbidity compared with transfemoral transcatheter aortic valve implantation. We aimed to compare access-related complications and survival using propensity score matching.

Methods And Results: Prospective, single-center registry of 1000 consecutive patients undergoing transapical and transfemoral transcatheter aortic valve implantation between May 2008 and April 2012.

Ruptures of the device landing zone in patients undergoing transcatheter aortic valve implantation: an analysis of TAVI Karlsruhe (TAVIK) patients.

Background: Aortic rupture of the device landing zone is a rare complication of transcatheter aortic valve implantation (TAVI) and it is associated with significant mortality.

Methods: This study reports on the experience of a single-center in a case series of more than 1,000 implants. We explored patient and procedural characteristics aiming at identifying variables that increase the risk for aortic root rupture.
