Commentary: Reintervention for a failed surgical aortic bioprosthesis: Procedure- or patient-driven strategy?

[Transcatheter aortic valve-in-valve implantation for failed aortic bioprosthesis].

Percutaneous valve replacement for severe aortic stenosis has been shown to be an alternative treatment option for high surgical risk patients. We describe our first valve-in-valve procedure in a patient with a degenerated aortic bioprosthesis and severe regurgitation.

Matched Comparison of Self-Expanding Transcatheter Heart Valves for the Treatment of Failed Aortic Surgical Bioprosthesis

Background—Transcatheter valve-in-valve implantation is an established therapy for high-risk patients with failed surgical aortic bioprosthesis. There are limited data comparing outcomes of valve-in-valve implantation using different transcatheter heart valves (THV). Methods and Results—Patients included in the Valve-in-Valve International Data registry (VIVID) and treated with selfexpanding TH...

Edwards Intuity Aortic Bioprosthesis in Patient with Bicuspid Aortic Valve

Bicuspid aortic valve (BAV) is generally considered to be a contraindication to sutureless aortic valve replacement (AVR). Implantation of the Edwards Intuity aortic bioprosthesis is an innovative approach associated with superior hemodynamic performance, significantly reduced myocardial ischaemia and cardiopulmonary bypass times and proves to be suitable for type 1 and 2 of bicuspid aortic val...

IDIOPATHIC PERFORATION OF PORCINE AORTIC BIOPROSTHESIS 579 Aortic Bioprosthesis in the Aortic Position

The report of a failure of a glutaraldehyde-preserved porcine aortic xenograft bioprosthesis in the aortic position after 13 months is presented. Severe aortic regurgitation resulted from three “idiopathic” perforations in one of the cusps, and a linear tear in another cusp. Light and electron microscopy showed generalized degeneration of collagen throughout the faulty valve. The absence of a p...
