Filter by:Introduction: The presence of pulmonary hypertension (PH) in atrial septal defect (ASD) poses a clinical challenge on whether or not to close the defect. Closing the defect increases the risk of low cardiac output syndrome (LCOS), while leaving the defect open may eventually lead to irreparable shunt reversal, hypoxemia, and death. The implementation of a fenestrated patch may halt LCOS while adding volume to the left heart. Methods: this is an analytical observational study involving patients with ostium secundum defect with PH who were operated on in Dr. Soetomo Hospital between January 2017 and October 2021. The aim of this study is to evaluate the improvement in left ventricular size during both systole and diastole.
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.
The investigators propose to translate confocal microscopy for use during open heart surgery. This tool will help discriminate between various types of tissues in the heart during surgery. One of the most feared complication after heart surgery is heart block. This flexible fiberoptic confocal microscope will help discriminate between the various types of tissues in the heart and thus help avoid injury to the conduction tissue during surgery.
Evaluate the safety and efficacy of the GORE® CARDIOFORM ASD Occluder in the percutaneous closure of ostium secundum atrial septal defects (ASDs)
All patients awaiting to have either a left atrial appendage closure (LAA) or patent foramen ovale (PFO) or Atrial Septal Defect (ASD) closure device as part of standard care will be identified and reviewed in cardiology clinics. These patients will be placed on waiting list to undergo the procedure. Patient-participants will be consented on the date of admission for device closure implantation. The study will recruit 20 patients divided into; 10 patients undergoing PFO/ASD closure and 10 patients undergoing LAA closure. EPC will be measured on the day of the device implantation, day 0 and prior to discharge on day 1. Patient participants are admitted overnight after the device closure implantation. Then on subsequent out patient cardiology research clinic follow appointments on days (3-4) and (7-8).
The purpose of this multi-center, non-interventional, prospective, post-market clinical study is to collect real world data on patient outcomes and evaluate the procedural success and performance of the Lifetech CeraFlex™ occluders for patients with secundum type Atrial Septum Defect (ASD), Patent Foramen Ovale (PFO) or Patent Ductus Arteriosus (PDA).
This clinical trial will determine the safety and effectiveness of intravenous L-citrulline in children undergoing cardiopulmonary bypass during heart surgery. Participants will be randomly assigned to either L-citrulline or a placebo (a substance that has no medicine in it). Citrulline is a protein building block in the body that can convert into another substance, nitric oxide (NO), which controls blood pressure in the lungs. Increased blood pressure in the lungs can be an important surgical problem; it may also lead to problems following surgery, such as severe high blood pressure in the lungs (pulmonary hypertension), increased time spent on a breathing machine, and a longer stay in the intensive care unit (ICU). The hypothesis of this study is that perioperative supplementation with intravenous citrulline will increase plasma citrulline, arginine and NO metabolites and prevent elevations in the postoperative PVT leading to a decrease in the duration of postoperative invasive mechanical ventilation. The objective of this study is to determine in a randomized placebo controlled phase IB multicenter clinical trial if a revised protocol of intravenous L-citrulline delivery given perioperatively achieves a plasma citrulline level of > 100 umol/L in children undergoing surgical repair of an atrial septal defect,ventricular septal defect or an atrioventricular septal defect.
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
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.
The purpose of this study is to examine the pharmacokinetics, pharmacodynamics, and pharmacogenomics of dexmedetomidine in the following three pediatric patient populations: patients with bi-directional cavopulmonary anastomosis or a Fontan procedure, patients who have had a cardiac transplant, and patients with otherwise normal physiology who are undergoing closure of a patent ductus arteriosis or atrial septal defect.
