Filter by:This study is a prospective, randomized study of patients with single ventricle heart disease who are to undergo superior cavo-pulmonary anastomosis, or "Glenn" operation. Such patients have historically undergone cardiac catheterization to ensure suitability for the procedure. Cardiac magnetic resonance imaging (cardiac MRI) is a newer technology that provides excellent anatomic and functional imaging of the heart. This study is designed to demonstrate our hypothesis that cardiac magnetic resonance imaging will provide comparable information to catheterization, with less side effects.
This is a study to determine the safety and efficacy of liothyronine sodium/triiodothyronine (Triostat), a synthetic thyroid hormone, when given to infants with congenital heart disease during cardiopulmonary bypass surgery.
Genetically inherited heart diseases (familial cardiopathies) are conditions affecting the heart passed on to family members by abnormalities in genetic information. These conditions are responsible for many heart related deaths and illnesses. Researchers are interested in learning more about the specific genetic abnormalities causing heart diseases. In addition, they would like to find out how these abnormal genes can contribute to the development of other medical problems. In order to do this, researchers plan to study patients and family members of patients diagnosed with genetically inherited heart disease. Those people participating in the study will undergo a variety of tests including blood tests, echocardiograms, and magnetic resonance imaging studies (MRI). These tests will be used to help researchers find the genetic problem causing the familial cardiopathy. Researchers hope that the information gathered from this study can be used to develop better medical care through early diagnosis, management, and treatment plans.
Dilution of blood caused by cardiopulmonary bypass (the heart-lung machine) during open heart surgery is associated with decreased concentrations in the blood of coagulation factors. This can be extreme in infants because of their small blood volumes and can lead to impairment of the normal blood clotting mechanism and excessive bleeding after the operation. Transfusion of fresh whole blood has been shown to be an effective treatment because fresh blood is rich in coagulation factors. However, it is difficult to obtain truly fresh blood from a blood bank. We hypothesized that fresh blood drawn from the patient and given back after cardiopulmonary bypass would improve the clotting mechanism. In our study, the infants in the treatment group have some of their own fresh blood removed after they are anesthetized for the operation and before they are placed on cardiopulmonary bypass. This blood is then given back to them after completion of cardiopulmonary bypass. Infants in the control group will not have their own blood removed but will undergo cardiopulmonary bypass. We will compare the two groups by drawing blood samples that measure coagulation tests.
The purpose of this study is to compare the effects of diluted hematocrit (HCT) levels of 35% versus 25% during hypothermic cardiopulmonary bypass (CPB) in infants with d-transposition of the great arteries, a malformation of the heart vessels.
To identify genes involved in the pathogenesis of three types of congenital heart disease, atrial septal defects, paramembranous ventricular septal defects, and atrioventricular canal defects.
To conduct an epidemiologic study of persistent pulmonary hypertension of the newborn ( PPHN) infant.
To identify genes involved in the pathogenesis of congenital heart disease, including atrial septal defects (ASDs), paramembranous ventricular septal defects (VSDs), and atrioventricular canal defects (AVCDs).
To determine genetic mechanisms responsible for congenital cardiovascular malformations.
To create a registry of all Oregon children undergoing surgical repair of congenital heart disease since 1958 in order to determine mortality, morbidity, and disability after surgery and to assess the safety of pregnancy in women with corrected congenital heart disease and the risk of prematurity and occurrence of congenital heart defects in offspring.
