Filter by:Patient-specific, 3D printed models have been utilized in preoperative planning for many years. Among researchers and clinicians, there is a perception that preoperative exposure to 3D printed models, derived from patient images (CT or MRI), aid in procedural planning. 3D printed models for heart surgery have the potential to improve a clinician's preparedness and therefore may reduce surgically-related morbidity and mortality. This randomized clinical trial aims to evaluate whether pre-procedural planning of surgeons exposed to a patient-specific 3D printed heart model will decrease cardiopulmonary bypass time, morbidity, and mortality.
Heart failure is a common long-term complication in patients with congenital heart disease (CHD). Medical treatments to promote regeneration of new healthy heart muscle cells have the potential to provide new heart failure treatments for these patients. The development of such therapies is limited by the poor understanding of the ways in which heart muscles grow after birth. Investigators have learned that humans without heart disease generate new heart muscles cells up to the age of 20 years old and that this is decreased in patients with congenital heart disease like Tetralogy of Fallot. Investigators are trying to determine if treatment with a medicine called Propranolol can increase heart muscle cell proliferation and, with that, normalize heart growth. Investigators will examine discarded heart muscle tissue that is obtained during surgery for the presence of new heart muscle cells. Propranolol is approved by the Food and Drug Administration (FDA) to treat a certain kind of benign tumor in infants (hemangioma), but it is not currently approved by the FDA to increase heart muscle growth.
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 purpose of this study is to investigate the security and validity of transesophageal echocardiography(TEE)-guided perventricular device closure(TPDC) through minithoracotomy in treatment of infundibular ventricular septal defect(IVSD) with asymmetric occluder.
The purpose of this study is to utilize cardiac imaging data acquired as part of the standard of care for these patients, such as MRI, 3D echo, and CT, and existing 3D reconstruction protocols to assess the feasibility of using surgical planning in the treatment of patients with complex cardiac defects. The specific aims of the project are as follows: 1. Develop a protocol to reconstruct heart models from patient imaging data and perform "virtual" surgery on reconstructed 3D anatomy using appropriate, pre-existing patient datasets. 2. Use the developed protocol to prospectively plan and evaluate the possible surgical options for new patients. 3. Validate that the optimal virtual anatomy agrees with what was surgically implemented using post-operative patient scans, when available.
This study will investigate Ebstein's anomaly, a congenital abnormality of the tricuspid valve of the heart and try to identify the genetic origins of the disease. Adults and children 2 years of age and older with Ebstein's anomaly and healthy volunteers may be eligible for this study. Participants undergo the following procedures: - Blood tests: Three tube of blood will be collected, with the total amount limited to about half a teaspon for each two pounds of body weight. - Saliva sample collection: A small amount of saliva is collected by spitting into a sterile container. - Oral (cheek) swab: Cells are collected from the mouth using a soft brush to swab the inside lining of the cheek. - Electrocardiogram: The electrical activity of the heart is recorded using electrodes placed on the chest. - Echocardiogram: Heart function is assessed using ultrasound.
