Filter by:Atrial septal defects (ASD) account for 10% of all congenital heart defects [1]. Hemodynamic consequences of an ASD are dilatation of the right atrium and right ventricle (RV) because of the volume overload due to the left-to-right shunt through the ASD.For several decades, surgical closure has been considered the standard method of repairing a secundum ASD [2]. Surgical repair, albeit enjoying a high success rate, negligible mortality, and good long-term outcome, is associated with morbidity, discomfort, and thoracotomy scars [3]. That is why the transcatheter closure of the ASD has more recently become an alternative to the surgical procedure [4]. During the last decade , ASD device closure , has finally replaced surgical ASD repair in most patients as the standard method of repair for the secundum ASD[5,6]. Cardiac arrhythmias and right chamber enlargement are well known long-term sequelae of atrial septal defect (ASD) [7]. Therefore, many authors suggest ASD closure before adulthood [8,9]. Classical ECG findings for a significant ASD are prolongation of the PR interval, prolongation of the QRS duration and right axis deviation of the QRS [10]. Percutaneous ASD closure is an ideal situation to study changes of RV dimensions and their impact on ECG as interferences from cardiopulmonary bypass, cardiac incisions and sutures on the right atrium and on the interatrial septum are excluded[11].
A multicenter, randomized, parallel-controlled clinical trial to evaluate the efficacy and safety of a new atrial septal defect occluder, ReAces®, and delivery system for the treatment of atrial septal defect occlusion. Compared with the traditional atrial septal occluder, this new atrial septal occluder supports re-puncture after occluder implantation. Thus those patients who have undergone atrial septal defect closure with the novel device may be eligible for future radiofrequency ablation of atrial fibrillation or mitral valve intervention. The trial is expected to enroll 128 patients who will be randomly assigned to the test group or control group in a 1:1 ratio. Patients in test group will received ReAces occluder，and the others the regular occluder.The experiment is scheduled to enroll 128 patients who will be randomly allocated to one of two groups: test or control. Patients in the test group will receive a ReAces occluder, while those in the control group will receive a standard occluder.The safety and efficacy of the two groups at 1 year after surgery will be compared.
This is a randomized, double-blind, placebo controlled, multicenter study to compare the efficacy and safety of L-citrulline versus placebo in patients undergoing surgery for congenital heart defects. Eligible patients undergoing repair of a large unrestrictive ventricular septal defect (VSD), a partial or complete atrioventricular septal defect (AVSD), or an ostium primum atrial septal defect (primum ASD) will be eligible for enrollment.
STITCH - Prospective Multi-Center Comparative Parallel Concurrent Study of the NobleStitch™ EL versus FDA approved Amplatzer Occluder device for closure of Patent Foramen Ovale to prevent recurrent ischemic stroke.
The purpose of this observational registry is to report real-world safety and performance of VeriSight for ultrasound guided ICE imaging in percutaneous cardiac intervention procedures when used in standard clinical practice.
Establish a cardiovascular biomarker profile to help screening for congenital heart disease in infants and children as well as use non-invasive cardiac imaging in combination with such profiling to better predict the need for future cardiac interventions such as open heart surgery or cardiac catheter intervention selected types of with congenital heart disease.
Evaluation of the safety and efficacy of the reSept ASD Occluder to treat patients with clinically significant secundum atrial septal defect
The objectives of the study are: - To determine the efficacy of the Figulla Flex II device compared with that of the Amplatzer ASO device for transcatheter closure of secundum atrial septal defects - To determine the safety of the Figulla Flex II device compared with that of the Amplatzer ASO device for transcatheter closure of secundum atrial septal defects This is a randomized, controlled, multi-centre trial of the efficacy and safety of the Occlutech septal occluder (Figulla Flex II) compared to the AGA septal occluder (Amplatzer ASO) for transcatheter closure of secundum atrial septal defects in patients.
A single-arm, non-randomized, multi-center clinical study of the Amplatzer™ Trevisio™ Intravascular Delivery System for facilitating percutaneous, transcatheter implantation of the Amplatzer™ Occluder Devices. NOTE: The enrollment for the VSD cohort is still recruiting (3 subjects at this moment); therefore, the overall status of the study is Recruiting.
This is an open-label, randomized, controlled trial of iatrogenic atrial septal defect closure with the an atrial septal occluder versus usual care observation in patients post-mitral valve intervention requiring large bore transspetal access.
