The majority of prosthetic heart valves currently implanted are tissue that can be expected to degenerate with time and eventually fail. Repeat cardiac surgery replace these is associated significant morbidity mortality. Transcatheter valve implantation within a failed bioprosthesis, "valve-in-valve" procedure, may offer less invasive alternative.Valve-in-valve implantations were performed in 24 high-risk patients. Failed aortic (n=10), mitral (n=7), pulmonary (n=6), or tricuspid (n=1)...
AimsMigraine with aura and patent foramen ovale (PFO) are associated. The Percutaneous Closure of PFO in Migraine Aura (PRIMA) trial is a multicentre, randomized to investigate the effect percutaneous closure patients refractory medical treatment.
Background— Off-label use of transcatheter aortic and pulmonary valve prostheses for tricuspid valve-in-valve implantation (TVIV) within dysfunctional surgical (TV) bioprostheses has been described in small reports. Methods Results— An international, multicenter registry was developed to collect data on TVIV cases. Patient-related factors, procedural details outcomes, follow-up were analyzed. Valve-in-ring or heterotopic TV procedures not included. Data collected 156 patients with...
<h3>Importance</h3> Recent epidemiologic and therapeutic advances have transformed understanding of the role approach to patent foramen ovale (PFO) in ischemic stroke. Patent is likely responsible for approximately 5% all strokes 10% those occurring young middle-aged adults. <h3>Observations</h3> Randomized clinical trials demonstrated that, prevent recurrent stroke patients with PFO an otherwise-cryptogenic index stroke, closure superior antiplatelet medical therapy alone; these provided...
Background— Transcatheter valve implantation inside failed bioprosthetic surgical valves (valve-in-valve [ViV]) may offer an advantage over reoperation. Supra-annular transcatheter position be advantageous in achieving better hemodynamics after ViV. Our objective was to define targets for that would improve Methods and Results— Cases from the Valve-in-Valve International Data (VIVID) registry were analyzed using centralized core laboratory assessment blinded clinical events. Multivariate...
To examine the outcomes in patients with moderate or severe pulmonary arterial hypertension (PAH) undergoing percutaneous atrial septal defect (ASD) closure.Retrospective study.Teaching hospital-based study.Fifty-four (n = 34) PAH 20) who underwent successful device implantation between 1999 and 2004 were included study. Clinical transthoracic echocardiographic data reviewed. Pulmonary was classified as (50-59 mm Hg) (>or=60 according right ventricular systolic pressure (RVSP) calculated by...
Abstract Objectives: Early clinical outcomes in selected high‐risk patients undergoing catheter‐based aortic valve replacement (AVR) compare favorably with conventional surgical AVR. Improved understanding of the mechanisms success and failure transcatheter AVR will likely improve further. To this end, we examined our experience during developmental phases describe causes management prosthetic malposition. Methods: Transcatheter balloon‐expandable was performed 170 at two centers....
Conduits placed in the right ventricular outflow tract (RVOT) have limited longevity which often requires increasingly complex reoperations. Transcatheter pulmonary valve implantation improves conduit hemodynamics through a minimally invasive approach. We present data for 7 patients treated with Edwards SAPIEN transcatheter heart (THV).Patients' ranged age from 16 to 52 years, one was female, and all had NYHA class II-III symptoms. Patients homografts that been 2-25 years earlier during Ross...
