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...

OBJECTIVE Aortic valve replacement with Braile bovine pericardial prosthesis has been routinely done at the Heart Institute of the Universidade de São Paulo Medical School since 2006. The objective of this study is to analyze the results of Braile Biomédica® aortic bioprosthesis in patients with aortic valve disease. METHODS We retrospectively evaluated 196 patients with aortic valve disease ...

BACKGROUND Severe peripheral arterial disease may pose a limitation to the applicability of trans-arterial aortic valve implantation in patients who are otherwise candidates. For this reason, transapical aortic valve implantation has been proposed as a possible alternative. OBJECTIVE To evaluate the acute safety and performance of a specially designed delivery system, the CoreValve Tranzap de...

A case of Ehlers Danlos syndrome is described in a 54-year-old Caucasian male. He had calcific aortic valve disease and dilatation of the ascending aorta. An aortic valve replacement was performed using a Starr prosthesis.

Classical aortic valve replacement is often fraught with negative outcomes for patients. When replacing the a mechanical prosthesis, patient associated life use of indirect anticoagulants, which leads to hemorrhagic and thrombotic complications. In case biological fairly frequent complication early calcification and, consequently, high frequency dysfunctions prosthesis. addition, prosthetics he...

Aortic valvular stenosis remains the most common debilitating valvular heart lesion. Despite the benefit of aortic valve (AV) replacement, many high-risk patients cannot tolerate surgery. AV implantation treats aortic stenosis without subjecting patients to sternotomy, cardiopulmonary bypass (CPB), and aorta cross-clamping. This transcatheter procedure is performed via puncture of the left vent...

An apico-aortic conduit (AAC) is an alternative therapy in patients with aortic valve stenosis and severe concomitant disease. We investigated whether it is feasible to create an apico-aortic conduit off-pump with a newly developed, stent-based coring- and cannulation-device in the animal model. A new self-expandable, stent equipped and hooked prosthesis and a sheath enabling both airtight remo...
