Filter by:A prospective of 30 patients with symptomatic severe congenital valvular pulmonary stenosis who are indicated for percutaneous balloon pulmonary valvuloplasty . the aim is to 1. - evaluate electrical and mechanical remodeling of RV 6 months following balloon dilation 2. - evaluate Functional capacity using 6MWT and SaO2 before and 6 months following BPV
The aim of this study is to compare the effect of different anesthetic drugs used for induction of anesthesia ketamine versus sevoflurane on the RV pressure in pediatrics undergoing balloon dilatation for congenital pulmonary stenosis.
The MASA Valve Early Feasibility Study (MVEFS) multi-site interventional clinical trial within the United States of America with each center following a common protocol.The objective of the trial is to evaluate the safety and probable benefit of MASA Valve in the indicated subset of patients requiring Right Ventricular Outflow Tract Reconstruction (RVOTR). As an early feasibility study, the purpose is determine the feasibility of success of the device in order to gather early data towards a future pivotal study and/or regulatory clearance submission.
This study investigates damage of the right cardiac chamber in adult patients with a congenital heart defect involving the pulmonary valve (the heart valve between the right cardiac chamber and the lungs). The investigators want to investigate if novel, less invasive techniques are feasible to assess damage of this right cardiac chamber, to improve follow-up and timing of intervention (valve replacement) in this group of patients.
Correct assessment of right ventricular function by transthoracic echocardiographic examination in pediatric patients with congenital valvular pulmonary stenosis after Percutaneous Balloon Pulmonary Valvuloplasty
This clinical trial is studying the use of different levels of oxygen exposure during and after cardiopulmonary bypass in eligible infants to learn about its safety during heart surgery. In addition to having the various doses of oxygen, patients that participate will also have blood samples, ultrasounds of the head, and brain wave patterns monitored. The hypotheses of this trial are: - that there will be no difference with regards to adverse events between the infants in the normoxia group compared to the infants in the standard of care group - there will be a significant difference in the measured partial pressure of oxygen (PaO2) values between the two treatment groups. - the use of normoxia during cardiopulmonary bypass and in the immediate post-operative period will result in clinically significant decrease in oxidative stress as measured by thiobarbituric acid reactive substances (TBARS) after cardiac surgery
The goal of this study is to test the hypothesis that fiberoptic confocal microscopy (FCM) imaging during repair of common congenital heart defects is a useful adjunct for avoidance of conduction abnormalities.
The purpose of the study is to evaluate the safety and effectiveness of the PULSTA Transcatheter Pulmonary Valve (TPV) System for the treatment of congenital or acquired pulmonary valve stenosis and/or regurgitation who require pulmonary valve replacement.
This study will assess the safety and performance of the GORE PV1 Device for replacement of the pulmonary valve and reconstruction of the Right Ventricular Outflow Tract (RVOT).
The purpose of this study is to evaluate the safety and effectiveness of the TPV in patients with pulmonary valve dysfunction.
