OBJECTIVES We sought to analyze safety, efficacy, and follow-up results of percutaneous closure of perimembranous ventricular septal defects (pmVSD). BACKGROUND Results of pmVSD transcatheter closure have been reported in the literature; however, follow-up data are still limited. METHODS Between January 1999 and June 2006, 104 patients underwent(More)
OBJECTIVES To develop a modified technique for stenting the atrial septum in the treatment of patients with a failing Fontan operation or pulmonary hypertension. SETTING Two tertiary referral centres. STUDY DESIGN Prospective collaborative clinical study. PATIENTS AND METHODS A stent was mounted on a standard valvoplasty balloon catheter which was(More)
BACKGROUND Recent advances in technology have provided the opportunity for off-line analysis of digital video-clips of two-dimensional (2-D) echocardiographic images. Commercially available software that follows the motion of cardiac structures during cardiac cycle computes both regional and global velocity, strain, and strain rate (SR). The present study(More)
AIM To report the experience of 23 tertiary referral European Centres on transcatheter closure of congenital ventricular septal defects (VSD). METHODS AND RESULTS Implantation of transcatheter devices was attempted in 430 patients (pts) with congenital VSDs until July 2005. The following anatomic types were present: 119 muscular, 250 perimembranous, 16(More)
BACKGROUND Intravascular stenting is the procedure of choice in the treatment of vascular stenoses. However, in infants and small children large sheaths are needed, and adult-size stents cannot be implanted. The Valeo Biliary Lifestent (Edwards Lifesciences Irvine, CA) is low profile and can be dilated up to 18-20 mm. We aimed to report on early and(More)
Traditionally, medical professionals have entrusted the parents of children with chronic illness with the task of imparting knowledge about the illness to the children. This practice assumes that parents understand the illness, and that they pass on their knowledge in a manner appropriate for the individual child. The aim of our study was to assess the(More)
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(More)
BACKGROUND About 50% of patients with cryptogenic stroke have a patent foramen ovale (PFO). The recurrence rate of paradoxical embolism is higher if a PFO is detected. METHODS Thirty-five patients with PFO and > or = 1 thromboembolic event due to paradoxical embolism were included in the study (23 males, 12 females, mean age 47.8 +/- 14 years, mean weight(More)
BACKGROUND AND AIMS Percutaneous implantation of pulmonary valve has been recently introduced in the clinical practice. Our aim was to analyze data of patients treated in Italy by using the Melody Medtronic valve. METHODS Prospective, observational, multi-centric survey by means of a web-based database registry of the Italian Society of Pediatric(More)
BACKGROUND The Amplatzer septal occluder (ASO) allows the percutaneous closure of small to very large atrial septal defects (ASDs). The CardioSEAL/STARflex (CS/SF) can be used only for closure of small to moderate ASDs (stretch size up to 18 mm). These 2 devices are widely used in clinical practice. Therefore, a comparison of their use in the closure of(More)
