Filter by:The goal of this observational study is to evaluate the effectiveness and safety of vibro-acoustic pulmonary therapy (VAPT) in complex therapy for the acute respiratory failure of mixed type I-II stages in comparison with percussion massage in cardiac surgical patients in the early postoperative period.
Sinus venosus defect (SVD) accounts for 10% of atrial septal defects and is characterized by an anomalous pulmonary venous return in the superior vena cava associated with a high situated atrial septal defect. Since 2013, transcatheter correction of this congenital heart disease has emerged as a new treatment option. The procedure involves placement of a covered stent in the superior vena cava that tunnels the anomalous pulmonary venous return to the left atrium. Preliminary results are limited but promising. The devices to be used depend on anatomic considerations. XXL stents than 70mm are often required. Today, the availability of CE marked stents is limited. There have been recent reports of successful corrections with the specifically developed Optimus XXL 100mm covered stent (ANDRATEC) with compassionate approval from the Agence Nationale de Sûreté du Médicament in France. Setting up a feasibility study to investigate the use of medical devices in this indication was required. The objective of this project is to study the feasibility, efficacy and safety of the Optimus stent in this newly developed transcatheter procedure, in comparison with the gold-standard surgical method. A French national multicenter comparative cohort study including all eligible patients referred for transcatheter correction of SVD was designed. The feasibility of the transcatheter procedures will be investigated beforehand by virtual digital simulation and simulation on a 3D printed model. The procedures will then be performed in centers of the M3C network for complex congenital heart diseases (CARDIOGEN). The primary endpoint will be a composite of efficacy, defined as complete occlusion of the shunt, and safety, defined as the absence of major events at 6 months. The secondary endpoints will be anatomical, functional and psychosocial (quality of life). It is expected that transcatheter treatment gives comparable results to surgery on the primary endpoint. This could justify the further development of this procedure as an alternative to surgery and facilitate the validation of dedicated equipment.
The purpose of this study is to evaluate pain control following pediatric cardiac surgery with the use of local anesthesia via an ultrasound guided regional anesthetic technique compared with surgeon delivered wound infiltration.
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.
Evaluation of the safety and efficacy of the reSept ASD Occluder to treat patients with clinically significant secundum atrial septal defect
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 a proposal, for the first time in Canada, to examine the comparative effectiveness of three commercially available devices (ASO, FSO, and GAO/GSO) for transcatheter closure of atrial septal defects (ASD) in adults using a pilot randomized controlled trial.
Prospective randomized multicenter trial of about 100 subjects enrolled in 3-5 centers. Patients will be randomized to two groups in equal proportion (50 in each). To precise the function of this device on reducing technical difficulties and conquering learning curves, it is required that the doctor should be able to independently do echo-guided percutaneous interventions and his cases should be more than 20 but less than 100. Experimental group is allocated to use novel interventional guidewire for echocardiography guided percutaneous interventions for ASD, control group will be treated by cook lunderquist guidewire. If echo-guided procedure does not work well, the procedure will be immediately replaced by conventional procedure guided by radiology. To evaluate the effectiveness and safety comprehensively, variables are defined as success rate, duration of procedure, times of arrhythmia, times of misguided to tricuspid valve, cardiac perforation, cardiac tamponed, complications in peripheral vessels etc.
