NCT05362721
Coarctation of the aorta accounts for 4-7% of all congenital heart disease. While stent therapy, when feasible, is the standard of care for coarctation, it may not completely improve the work (and afterload) of the heart due to its effects on the elasticity of the aorta. This study will provide the information needed to understand the effects of current management on the cardiac mechanics and work.
NCT07131111
This study aims to assess: 1. Aortic geometrical changes and their relationship to hypertension and cardiovascular events. 2. Aortic geometrical differences between healthy individuals and patients with repaired coarctation of the aorta.
NCT06150560
The purpose of this study is to evaluate the effectiveness and mechanism of action of Losartan in the treatment of coarctation of aorta.
NCT04106479
Neonatal patients with congenital heart defects (CHD) have changing physiology in the context of transitional period. Patients with CHD are at risk of low perfusion status or abnormal pulmonary blood flow. Near infrared spectroscopy has been used in neonatal intensive care units (NICU) to measure end-organ perfusion. The investigator plan on monitoring newborns with CHD admitted to the NICU with NIRS and echocardiography during the first week of life and correlate measures of perfusion from Dopplers to cerebral and renal NIRS.
NCT06768008
The purpose of this two-way cohort study was to explore whether an integrated prenatal and postnatal treatment model for neonates with critical congenital heart disease (CCHD) could be effective in avoiding preoperative morbidities, creating an ideal timing for surgery, thereby reducing postoperative in-hospital mortality, and improving surgical prognosis compared with the traditional model of care. In addition, in neonates with CCHD associated with the right cardiac system, the investigators aim to further investigate whether early postnatal cardiac surgery has the potential advantage of obtaining a time window for myocardial regeneration and thus improving myocardial remodeling. The aim of this study is to improve the diagnostic and therapeutic capacity of critical congenital heart disease and to promote the integrated prenatal-postnatal treatment model for clinical use. This will ultimately improve the quality of healthcare services for patients with cardiovascular diseases and lay the foundation for exploring guidelines for the treatment of cardiovascular diseases suitable for China's national conditions. The project will be jointly implemented by Beijing Anzhen Hospital , Capital Pediatric Research Institute, and 307 PLA General Hospital. Starting from January 1, 2022, the hospitals will continue to collect hospitalized cases of newborns with CCHD. The integrated prenatal and postnatal model is defined as a definitive diagnosis of CCHD in the fetal period (22-26 weeks), documentation of intrauterine transfer in our obstetrics department, subsequent initiation of an intrapartum or postpartum surgical plan after multidisciplinary consultation, and transfer to the pediatric heart center at the first hour of life, where the child is treated with either postpartum immediate or elective surgery, depending on patient status. For neonates who meet the indications for emergency surgery, surgery is performed immediately after birth. For neonates with non-emergency surgical indications, surgery is performed after birth adjustment to optimal status. The traditional model was defined as postpartum transfer via an outside hospital with routine interventions. The investigators then evaluate surgical prognosis and myocardial regenerative capacity to compare the effects of the two treatment models. This project will validate the advantages of an integrated prenatal and postnatal model over traditional models through real-world research and will improve prognosis in neonates with CCHD.
NCT02545790
This study is designed to learn more about children who have blockage of the left side of their heart. The goal is to determine how much the heart muscle has thickened before surgery and how it changes in the months after surgery. Investigators are also looking for blood tests that may help them predict which patients will have the most thickening pre-operatively and the best return towards normal after surgery. The findings of this study will help the investigators develop new tests to monitor affected patients and develop new therapies to help minimize heart thickening.
NCT04011956
This is a systemic research of Chinese aortic coarctation patients, aiming to determine risk factors and serial biomarkers of aortic coarctation in prognosis.
NCT03303768
Prenatal diagnosis of coarctation is difficult because the ductus arteriosus masks the isthmus narrowing. The problem lies in the fact that it is difficult to assert in utero diagnosis and to predict severity of neonatal symptomatology. However, it is essential to try to establish the diagnosis since it has been shown that the prenatal diagnosis improves survival and reduces morbidity.
NCT03074773
Anesthetic management for surgery of aortic coarctation needs special care due to severe pain during lateral thoracotomy incision, the intraoperative hemodynamic instability related to skin incision at lateral thoracotomy, clamping and declamping of the aorta, needs of large doses of analgesia perioperative, needs of vasodilators. Also, postoperative care of the patients after repair is very important issue. The investigators will compare the effect of para-vertebral block with bupivacaine alone or with dexamethasone on Intra and postoperative analgesia.
NCT00005190
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.
