Filter by:Currently, research on the effect of thiamine administration during transcatheter closure on the structure and function of the left ventricle by examining levels of matrix metalloproteinase-9 and tissue inhibitor of metalloproteinase-1 in children with left to right shunt congenital heart disease has never been carried out in Indonesia, so it is necessary carried out this research. This research was carried out by administering 100 mg of thiamine once per day to patients post transcatheter closure for 28 days. The parameters assessed were MMP-9, TIMP-1, and echocardiography to assess the structure and function of the left ventricle in CHD patients with left to right shunt lesions.
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 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.
The aim of this study is to evaluate the safety and efficacy of Absnow absorbable ASD closure system for treating patients with atrial septal defect.
Patients received a MitraClip procedure because of a leakiness of their mitral valves. During this procedure the atrioventricular valves were stuck together permanently via a clip which leads to a reduction of leakiness. As a result of this procedure a small hole remains at the cardiac septum which is called an atrial septal defect (ASD). In most cases the hole will close after a few weeks or months, but in many other cases not. Until now there is no exact data about the effect of this hole on the filling pressure in the heart or on the blood flow behaviour. So the aim of this study is a precise analysis of the blood flow mechanics during and after the MitraClip procedure to identify criteria to get more informations for a better strategy and regulation of the MitraClip procedure.
Background: Three-dimensional echocardiographic image for atrial septal defect (ASD) is useful for evaluation of defect size and shape. The investigators suggested optimal device size using three-dimensional transesophageal echocardiographic image and our formula in previous study. Purpose: In this study, the investigators seek to predict the correct device size and confirm the accuracy of the formula that we made before device closure in ASD patients.
