The purpose of this study was to compare patient populations, safety, feasibility, complications, and total costs of the transcatheter and transthoracic device closure treatments for secundum atrial septal defect.From January 2014 to December 2014, we enrolled 155 patients with secundum atrial septal defects in our hospital. The patients were divided into 2 groups: the 70 patients in group A un...
Background: Aneurysmal bone cysts (ABCs) could be treated by curettage, curettage and filler or even by resection. When located in the pelvis, surgery is always associated with excessive bleeding. Selective arterial embolization can be performed in pelvic ABCs as a preoperative procedure to minimize blood loss or could be used as a primary treatment option. Purpose: The purpose of this study is...
BACKGROUND Transcatheter embolisation is widely used to close pulmonary arteriovenous malformations (PAVMs) in patients with hereditary haemorrhagic telangiectasia (HHT). Data on the direct cardiovascular haemodynamic changes induced by this treatment are scarce. OBJECTIVES We investigated the direct haemodynamic effects of transcatheter embolisation of PAVMs, using non-invasive finger pressu...
PURPOSE In the present report we describe our clinical experience using specific image-based decision making and anatomic considerations for transcatheter valve-in-valve (ViV) implantation in degenerated xenografts with their pericardial leaflets externally mounted around the stent (Mitroflow [SORIN Group, Milan, Italy] or Trifecta [St. Jude Medical, St Paul, MN]). This design seems to increase...
OBJECTIVES To provide comprehensive illustrations of anatomy of the relevant vessels in large experimental animals in an interactive format as preparation for developing an effective and safe transcatheter technique of aortopulmonary and bidirectional cavopulmonary intervascular anastomoses. METHODS Computed tomographic angiographic studies in two calves and two sheep were used to prepare 3D ...
OBJECTIVE To report the clinical events leading to alteration of an anticoagulation regimen for patients undergoing transcatheter closure of an atrial shunt and how this affected migraine symptoms after the closure procedure. METHOD Audit of a change of anticoagulant regimen. RESULTS In the first few weeks after a closure procedure migraine frequency and severity increased despite treatment...
BACKGROUND Cardiovascular magnetic resonance (CMR) can provide important structural information in patients undergoing transcatheter aortic valve implantation. Although CMR is considered the standard of reference for measuring ventricular volumes and mass, the relationship between CMR findings of right ventricular (RV) function and outcomes after transcatheter aortic valve implantation has not ...
OBJECTIVES The goal of this study was to report the early and late complications experienced in atrial septal defect (ASD) transcatheter closure. BACKGROUND Atrial septal defect transcatheter occlusion techniques have become an alternative to surgical procedures. A number of different devices are available for transcatheter ASD closure. The type and rate of complications are different for dif...
BACKGROUND The objective of this study was to evaluate the timing, predictive factors, and prognostic value of cerebrovascular events (CVEs) after transcatheter aortic valve implantation. METHODS AND RESULTS The study included 1061 consecutive patients who underwent transcatheter aortic valve implantation with a balloon-expandable (64%) or self-expandable (36%) valve. CVEs were classified as ...
INTRODUCTION Surgical replacement for aortic stenosis is fraught with complications in high-risk patients. Transcatheter techniques may offer a minimally invasive solution, but their comparative effectiveness and safety is uncertain. We performed a network meta-analysis on this topic. METHODS Randomized trials on transcatheter aortic valve replacement vs surgery were searched. The primary out...
