Relative Survival After Transcatheter Aortic Valve Implantation: How Do Patients Undergoing Transcatheter Aortic Valve Implantation Fare Relative to the General Population?

BACKGROUND Transcatheter aortic valve implantation (TAVI) is indicated for patients with aortic stenosis who are intermediate-high surgical risk. Although all-cause mortality rates after TAVI are established, survival attributable to the procedure is unclear because of competing causes of mortality. The aim was to report relative survival (RS) after TAVI, which accounts for background mortality...

Balloon expandable transcatheter aortic valve implantation via the transfemoral route with or without pre-dilation of the aortic valve – rationale and design of a multicentre registry (EASE-IT TF)

BACKGROUND Transcatheter aortic valve implantation via the transfemoral route (TF-TAVI) is commonly performed as a treatment for severe aortic stenosis (AS) in patients at high surgical risk. Pre-deployment balloon aortic valvuloplasty (BAV) has generally been considered an essential step for preparing the valve landing zone for receipt of the prosthesis. However, there is little evidence suppo...

Transapical approach for transcatheter aortic valve implantation.

With the advancement of device technology and procedural techniques, most transcatheter aortic valve implantation (TAVI) procedures have been performed with the transfemoral approach in recent years (1). However, alternative approaches such as transapical, trans-subclavian, direct aortic and others still play an important role in patients with poor vascular access. Transapical approach is the o...

Short-term effects of transcatheter aortic valve implantation on neurohormonal activation, quality of life and 6-minute walk test in severe and symptomatic aortic stenosis.

OBJECTIVE This prospective study aimed to determine to what extent clinical symptoms and neurohumoral activation are improved in patients with severe aortic valve stenosis after transcatheter aortic valve implantation (TAVI) with the CoreValve prosthesis. METHODS From June 2008 to June 2009 consecutive patients with symptomatic severe aortic valve stenosis (area<1 cm(2)), age>or=75 years with...
