The purpose of this study is to evaluate the efficacy and safety of minimally invasive transthoracic device closure of ventricular septal defect. This is a multi-center randomized controlled trial. Because of the characteristics of this surgical clinical trials, surgeons, ultrasonic department doctors, anesthesiologists, operating room nurses and intensive care unit nurses are all need to be informed. Therefore the results of this trial need to be system evaluated through objec...
The purpose of this clinical trial is to verify the safety and effectiveness of the Fully Absorbable VSD Occlusion System and VSD Occlusion System produced by Shanghai shape memory alloy materials co., LTD. Clinical trials are designed as prospective, multicenter, randomized controlled, noninferiority clinical trials. Prospective randomized multicenter trial involving about 108 subjects will be enrolled in 4 centers. Patients will be randomized to two groups in equal proportion...
The purpose of the study is to compare exercise capacity, cardiac contractility, pulmonary vascular pressures and heart rate variability between patients with an atrial septal defect and healthy controls.
Multi centre, international, post market registry to monitor the clinical performance and safety of an atrial septal closure device with biodegradable framework in patients with clinically significant atrial septum defect (ASD) or patent foramen ovale (PFO) in routine clinical use
The objective of this registry is to gain more insight on the clinical use of the Occlutech perimembranous VSD occluder.
Prospective mono-center clinical study to evaluate the safety and effectiveness of an intracardiac septal closure device in patients with atrial septum defect (ASD)
The purpose of this study is to prospectively evaluate the incidence of hemodynamic compromise and to obtain long-term survival data on patients with the AMPLATZER Septal Occluder
The aim is to compare effective growth true hypoplastic pulmonary arteries using Right Ventricle Outflow Tract Reconstruction by femoral allogenic vein valve conduit and modified Blalock-Taussig shunt
The effect of Atrial Septal Defect (ASD) closure by using larger devices on the improvement in biventricular function remains an area of active research. Therefore, the aim of the current study is to assess the degree of improvement in biventricular dimensions and function by using 2-Dimensional echocardiography derived Strain and Strain Rate and Tissue Doppler. Moreover, to identify the relationship between the left and right ventricular systolic and diastolic function and dev...
Pulmonary arterial hypertension (PAH) in patients with congenital heart disease usually develops secondary to chronic volume overload of the pulmonary circulation following left to right shunt. This overload leads to elevated pulmonary artery pressure (PAP) and later to increased pulmonary vascular resistance (PVR), leading to right ventricular dysfunction, considerable morbidity and even mortality. Since PAH nowadays is mostly detected when symptoms occur and PAP are elevated...
Conventional right ventricular apical pacing may result in asynchronous ventricular contraction with delayed left ventricular activation, interventricular motion abnormalities, and worsening of left ventricular ejection fraction. His pacing is preserving a synchronous contraction and may prevent a decrease in left ventricular ejection fraction. Hypothesis: His-pacing preserves left ventricular function and is a feasable alternative compared to RV septal septal pacing in patie...
An atrial septal defect (ASD) is a hole in the heart that can lead to heart failure. Depending on the size and severity of the ASD, They can be treated during a heart catheterization with a special device that can permanently seal the ASD, but knowing the exact size and severity of the ASD is crucial. Newer MRI techniques may provide a better way at diagnosing the size and severity of an ASD. We compared MRI to other standard clinical ways for evaluating an ASD.
This study is for patients who have been diagnosed with either a Patent Foramen Ovale [PFO] or an Atrial Septal Defect [ASD]. These are a type of hole located in the wall that separates the top two (2) chambers of the heart. You have been recommended to receive an atrial septal occluder device [a device specifically designed to close PFOs and ASDs] implanted in your heart to close this hole. Because these devices are made of materials that contain nickel, this trial is being...
This clinical trial is a multi center, prospective, randomized, parallel study designed to compare septal to apical ICD lead placement.
This study will compare single coil right ventricular defibrillation leads for implanted cardioverter/defibrillators (ICDs) in the apical and high septal locations. It is hypothesized that RV septal positions are at least as good as apical positions using formally measured defibrillation thresholds(DFTs), and that they may have long term advantages in reducing left ventricular dysfunction.
The aim of this study is to determine whether three-dimensional tranesophageal echocardiography (3D TEE) assessment of ostium secundum atrial septal defect (ASD II) may be as efficient as two-dimensional (2D) TEE assessment complemented by the balloon-sizing during transcatheter closure of the defect.
The purpose of this study is to evaluate the long-term safety and efficacy of the GORE HELEX(tm) Septal Occluder in the treatment of ostium secundum atrial septal defects (ASDs).
The overall objective for this study is to test whether β2-agonists will affect the cardiopulmonary capacity of VSD-operated patients compared with un-operated VSD-patients and healthy age- and gender-matched controls.
The purpose of this feasibility study is to investigate the safety of the AMPLATZER® Membranous VSD Occluder for the treatment of hemodynamically significant Perimembranous Ventricular Septal Defects.
Ventricular septal defect (VSD) is one of the most common pediatric congenital malformations. In recent years, in view of the rapid rise of transthoracic minimally invasive hybrid closure for pediatric VSD in the clinical practice, precision assessment of perioperative its effectiveness and safety has already become an important issue that must be solved. On the basis of echocardiography, integrating with characteristics associated critical care, the investigators focus on prec...
With advances in interventional cardiac catheterization, ventricular septal defect (VSD) could be successfully treated via transcatheter device closure. Cardiac catheterization team of National Taiwan University Children's Hospital has recently treated more than 60 patients with VSD using this technique. Both treatment effect and follow-up results were encouraging. Of particular notice is that many patients experienced subjective improvement in exercise tolerance after VSD clos...
The Ventricular septal defect (VSD) is the most common of all congenital cardiac malformations. By modifying the Nit-Occlud® PDA Device the Nit-Occlud® Lê VSD Spiral System was designed. as a percutaneous, transcatheter device for occlusion of (peri)membranous and muscular ventricular septum defects (VSD) with a spiral coil. In this clinical investigation feasibility, safety and performance of the new cardiac occluder will be evaluated in accordance with European and US regu...
Optimal pacing strategy for patients with SND is still unknown, although several publications in the past years demonstrated a deleterious effect of ventricular pacing. However, pacing has always been apical in these trials, and to which extent this absence of pacing is beneficial for patients with very long PR intervals is still to be found. The aim of this study is to compare ventricular septal pacing to no pacing in patients with SND.
Severe pulmonary regurgitation is common in patients with Tetralogy of Fallot and results in progressive right ventricular dilatation and dysfunction. Pulmonary valve replacement is frequent in this population, and percutaneous procedures are increasing. Ventricular arrhythmias are a frequent late complication in patients with tetralogy of Fallot. The most common critical isthmus of ventricular tachycardias is between the pulmonary valve and the ventricular septal defect patch...
