Study of Energy Expenditure in Infants With Ventricular Septal Defects

PROTOCOL OUTLINE: Height, weight, and vital signs (including oxygen saturation by pulse oximetry) are measured on Day 1. Resting energy expenditure, oxygen consumption (VO2), carbon dioxide production (VCO2), and resting respiratory exchange quotient (RQ) are measured using open circuit respiratory calorimetry on Day 1. Patients undergo assessment of total daily ...

Phase N/A

Cell Therapy In Dilated Cardiomyopathy

This protocol describes a double-blind placebo controlled randomized clinical trial to evaluate the efficacy of bone marrow derived stem cell implants in 300 bazillion patients with dilated cardiomyopathy and heart failure in class III or IV of the New York Heart Association. The primary endpoint of this study is to ...


Therapy With Verapamil or Carvedilol in Chronic Heart Failure

Heart failure, irrespective of its etiology may be viewed as a progressive disorder initiated by a different events and sustained by a multifaceted pathophysiological mechanisms. Regardless of the nature of the initiating events and optimized therapy used, loss of functioning cardiac myocytes developed and the disease progressed. One potential explanation ...


Pediatric Exercise With Congenital Heart Defects (Kinderturnen Mit Angeborenem Herzfehler)

The study will be performed with a randomized crossover design. After the first assessment of coordinative capabilities children were randomized into two groups. One starts with exercised training for three months. After midterm assessment of the capabilities they will pause for another 3 months and reassessed. The second group will ...

Phase N/A

Aortic Regurgitation After Surgical Repair of Outlet-Type Ventricular Septal Defect

Progression of aortic regurgitation (AR) in repaired outlet (juxta-arterial, muscular outlet and perimembranous outlet) ventricular septal defect (VSD) remains unclear. From 1987 to 2002, 411 patients with complete follow-up after repair of outlet VSD constituted the study population. Study end point was aortic valve replacement or mortality. Aortic valve replacement ...

"Salvage Use" of Recombinant Factor VIIa After Inadequate Haemostasis in Complex Cardiac Surgery

11. 3 Methods Synopsis of Study: A multicentred randomised, double blind, placebo-controlled trial evaluating the efficacy and safety of activated recombinant factor VII (rVIIa) in complex cardiac surgery. Study will be conducted at Austin Hospital, Alfred Hospital and Warringal Private Hospital. The study will have two arms: 1. Those who ...


Role of Left Ventricular Pacing Site

Background. Cardiac resynchronization therapy has been shown to be effective in reducing symptoms and mortality in heart failure patients. However, very few is known about the importance of the left ventricular pacing site. Design. Single-blind, monocentric, randomized cross-over study comparing 11 left ventricular pacing sites in a random order. Intervention. ...

Phase N/A

Calcium Current in Human Heart Cells

Extrapolating pharmacological and surgical therapies from adult (AD) studies to infant (INF) patients is problematic because the knowledge of cellular electrophysiology and molecular biology of human INF heart cells is limited. The investigators have studied developmental differences in rabbit ventricular cells and now extend these studies to atrial and ventricular ...

Phase N/A

Varying Characteristics of Atherogenesis and Cardiopulmonary Bypass Inflammatory Response

BACKGROUND: Over the last decade there has been a tremendous growth in our understanding of genetic influences upon atherogenesis, coagulation, and fibrinolysis. Atherosclerosis plays a major role in the pathophysiology of coronary, cerebral, and peripheral vascular disease. Interventions directed towards the prevention of ASCVD have focused on the use of ...

Xeltis Bioabsorbable Pulmonary Valved Conduit Early Feasibility Study

This is a multi-center prospective, single-arm, non-randomized, open label study to assess feasibility of the Xeltis Bioabsorbable Pulmonary Valved Conduit in subjects requiring Right Ventricular Outflow Tract correction or reconstruction due to congenital heart malformations.
