OBJECTIVES Transcatheter aortic valve implantation (TAVI) has emerged as an effective treatment for high-risk patients with severe aortic stenosis (AS). The aim of our study was to compare the prevalence, characteristics and outcomes of high-risk patients treated prior to and after the availability of TAVI in our high-volume surgical institution. METHODS Among 879 consecutive patients treated...
BACKGROUND The incremental cost-effectiveness of transapical transcatheter aortic valve implantation (TAVI) is ill-defined in high-risk patients where aortic valve replacement (AVR) is an option, and has not been ascertained outside a randomized controlled trial. METHODS We developed a Markov model to examine the progression of patients between health states, defined as peri- and post-procedu...
BACKGROUND Surgical aortic valve replacement (SAVR) is the gold standard for treating aortic valve stenosis. It is a major operation that requires sternotomy and the use of a heart-lung bypass machine, but in appropriately selected patients with symptomatic, severe aortic valve stenosis, the benefits of SAVR usually outweigh the harms. Transcatheter aortic valve implantation (TAVI) is a less in...
BACKGROUND Little is known about preoperative predictors of resource utilization in the treatment of high-risk patients with severe symptomatic aortic valve stenosis. We report results from the prospective, medical-economic "TAVI Calculation of Costs Trial". METHODS In-hospital resource utilization was evaluated in 110 elderly patients (age ≥ 75 years) treated either with transfemoral (TF) or...
BACKGROUND Short-term results are presented from our first year of experience with transcatheter aortic-valve implantation [corrected] (TAVI) at the University Hospital of North Norway. MATERIALS AND METHODS TAVI was used to treat 25 patients with aortic stenosis [corrected] from September 2008 to August 2009. 25 patients operated with conventional aortic valve replacement (AVR) served as con...
PURPOSE Transcatheter aortic valve implantation (TAVI) has become an attractive therapeutic strategy for severe aortic stenosis (AS) in elderly patients due to its minimally-invasive nature. Therefore, early results of its clinical outcomes in elderly Korean patients were evaluated. MATERIALS AND METHODS We compared early clinical outcomes of TAVI, surgical aortic valve replacement (SAVR), an...
OBJECTIVE To determine the extent to which differences in generic quality of life (QOL) between transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (AVR) patients explained by EuroSCORE and heart-team operability assessment. METHODS A total of 146 high-risk patients with EuroSCORE > 6 and aged ≥ 75 years underwent TAVI (n = 80) or aortic valve replacement (n =...
S ince the first transcatheter aortic valve implantation (TAVI) by Dr. Alain Cribier was reported in 2002, the field of TAVI has grown steadily and, at times, exponentially.1 Surgeons and cardiologists have continued to innovate and broaden the range of applications for TAVI. Initially developed for aortic stenosis, TAVI has been performed by either a transfemoral or transapical approach. Subse...
AIMS To evaluate short-term clinical outcomes following transcatheter aortic valve implantation (TAVI) using CE-mark approved devices in Switzerland. METHODS AND RESULTS The Swiss TAVI registry is a national, prospective, multicentre, monitored cohort study evaluating clinical outcomes in consecutive patients undergoing TAVI at cardiovascular centres in Switzerland. From February 2011 to Marc...
BACKGROUND Chronic increased afterload due to severe aortic stenosis (AS) results in com-pensatory concentric left ventricular (LV) hypertrophy and LV dysfunction. These in turn cause remodeling of the left heart. The aim of this study was to investigate the acute effect of transcatheter aortic valve implantation (TAVI) on left atrial (LA) mechanics and LV diastolic function. METHODS The stud...
