OBJECTIVES The aim of this study was to compare the acute performance of the PLLA ABSORB bioresorbable vascular scaffold (BVS) (Abbott Vascular, Santa Clara, California) with second-generation metal drug-eluting stents (DES) in complex coronary artery lesions. BACKGROUND Thick polymer-based BVS have different mechanical properties than thin… (More)
INTRODUCTION AND OBJECTIVES Percutaneous paravalvular leak closure is a complex procedure with varying success rates; the lack of closure devices specifically designed for this purpose has hampered this technique. The characteristics of the Amplatzer Vascular Plug III appear to be well suited for paravalvular leak closures; however, the available data are… (More)
Fully bioresorbable vascular scaffolds (BVS) are a new approach to the percutaneous treatment of coronary artery disease. The BVS have not yet been fully tested in complex lesions, including chronic total occlusion (CTO). We report a CTO case successfully treated with a second-generation bioabsorbable drug-eluting scaffold.
5. patients and did not change. Regarding LV diastolic function, 28% of patients had normal filling, almost 69% had an impaired relaxation pattern, and 3% had pseudonormal filling. At the end of the study, E wave velocity had increased, E/A ratio had decreased, and deceleration time had shortened. At the end of follow-up, LV diastolic function had… (More)
We present the case of a patient with a high-output fistula between the right superficial femoral artery and femoral vein after left atrial appendage closure successfully treated with a PK-Papyrus covered coronary stent using a 6F guiding catheter. To the best of our knowledge this is the first time a PK-Papyrus coronary stent has been used in this setting.
Mechanical aortic valve prostheses are considered a limiting factor when contemplating percutaneous closure of mitral paravalvular leaks using a retrograde approach. However, transfemoral artery access and a retrograde approach have advantages over a trans-septal anterograde approach when the paravalvular defect is large with a significant gradient or when… (More)
The most common etiology of tricuspid stenosis is rheumatic, and in most cases it is associated with valvular regurgitation. Interestingly, there have been reports of tricuspid stenosis without associated valvular regurgitation, mostly related to pacemaker leads. Percutaneous tricuspid valvuloplasty may be a therapeutic alternative to surgery in cases of… (More)
Pulmonary vein (PV) stenosis (PVS) is a known complication of PV isolation procedures for AF (atrial fibrillation). PV angioplasty and stenting have been used as an effective therapy for PVS, yet high rates of restenosis are common. Experience with intravascular ultrasound (IVUS) in evaluating the PVS morphological characteristics and appropriate stent… (More)
