"Balloon withdrawal technique" to correct prosthesis malposition and treat paravalvular aortic regurgitation during TAVI.

چکیده
Transcatheter aortic valve implantation (TAVI) is an emerging technology used to treat high-risk patients with severe aortic stenosis. During TAVI with the CoreValve ReValving System, a balloon is used for the reduction of paravalvular regurgitation. However, in this paper, we describe the "balloon withdrawal" technique through which the positioning of a second valve can be avoided in case of initial malpositioning. The result of the technique was rather encouraging, and minimal paravalvular aortic regurgitation was recorded after echocardiographic assessment.

Technical challenge of transfemoral aortic valve implantation in a patient with severe aortic regurgitation.
Transfemoral aortic valve implantation (TAVI) has become an important interventional technique for patients with severe aortic stenosis (AS) and very high surgical risks. Several studies have demonstrated the feasibility and clinical success of TAVI procedures.1,2 Indications of transfemoral implantations of aortic valves are clearly defined, and TAVI should only be performed in patients with s...

Transcatheter aortic valve implantation (TAVI) is a recently developed surgical technique to treat symptomatic aortic valve stenosis in elderly and high-risk patients (Eltchaninoff et al., 2008; Ferrari & von Segesser, 2010). Compared to the standard aortic valve replacement surgery, the TAVI limits the surgical access to either a small minithoracotomy (transapical TAVI) or femoral approach (tr...

BACKGROUND Post-procedural aortic regurgitation (AR) has been described in a large number of patients receiving transcatheter aortic valve implantation (TAVI). OBJECTIVE The aim of this study was to examine the intraoperative 2-dimensional (2D) and 3-dimensional (3D) echocardiographic features of the aortic valve associated with significant post-procedural paravalvular AR. METHODS A total o...
متن کاملMultidetector row computed tomography parameters associated with paravalvular regurgitation after transcatheter aortic valve implantation.
Multidetector row computed tomographic (MDCT) assessment of aortic annulus dimensions and frame position and deployment have been associated with paravalvular aortic regurgitation (PAVR) after transcatheter aortic valve implantation (TAVI). The present evaluation investigated the (pre- and postprocedure) MDCT associates of PAVR ≥2+. In total, 123 patients referred for TAVI underwent clinical ev...
متن کاملQuantitative analysis of post-TAVI aortic regurgitation with cardiovascular magnetic resonance and the relationship to transthoracic echocardiography
Background Transcatheter Aortic Valve Implantation (TAVI) is increasingly used to treat patients with severe aortic stenosis at high surgical risk. The severity of post-implantation valvular or paravalvular regurgitation has been shown to adversely affect patient outcome. The aim of the study was to assess the prevalence and severity of aortic regurgitation (AR) at 6 months post-TAVI using card...
