Filter by:Patients with the transposition of great arteries (TGA) who undergo atrial switch operation and congenitally corrected TGA (ccTGA) patients have the right ventricle as their systemic ventricle. Function of the systemic right ventricle (SRV) could deteriorate which is associated with impaired prognosis. It is of paramount importance to understand the course and fate of these patients during a long-term follow-up to identify the determinants of adverse outcomes.
Transposition of great vessels are usually corrected by an arterial switch operation. This operation is often done during the first week of life as surgical delays lead to deconditioned left ventricle. On the other hand early surgery carries also risks as neonatal physiology may have problems adapting to an intervention under cardiopulmonary bypass, possible pulmonary hypertension. Arterial switch operation between 2008 and 2020 done at our center will be reviewed. Primary outcome will be mortality or severe postoperative morbidity. Patients will be divided in 2 groups according to the presence or absence of the primary outcome. After propensity score matching, they will be analysed according to the timing of operation.
Transposition of the great arteries (TGA) is a complex cyanotic congenital heart disease and patients suffer from a high mortality rate within one year of age without appropriate management. The therapeutic effect of arterial switch operation (ASO) is satisfactory with low surgery mortality of 2-5%, and thus, has become the treatment of choice for surgical correction of d-TGA. Outcomes of ASO in TGA in china are rare. This is a retrospective study reporting the outcomes of ASO in TGA.
In complete transposition of the great arteries (TGA) with previous atrial switch repair, and congenitally corrected transposition of the great arteries (ccTGA), the morphological right ventricle and its tricuspid valve continue to support the systemic circulation. This results in late complications including including sudden death. This retrospective multicentric study aims to evaluate the prevalence of SCD in a contemporary population of patients with a systemic RV and identify specific risk factors for SCD and hemodynamically significant ventricular arrhythmia This registry records demographics, clinical, imaging data, electrophysiological and laboratory of patients with a sRV and a transposition of the great arteries Primary end points are defined by sudden cardiac death, near-miss sudden death, as well as sustained VT requiring defibrillation.
This trial will test if adding nitric oxide (NO) gas to the cardiopulmonary bypass (CPB) circuit in infants undergoing an arterial switch operation (ASO) for Transposition of the Great Arteries (TGA) changes the incidence of major postoperative adverse events (AEs). Major postoperative AEs include cardiac arrest, emergency chest opening, use of ECMO (machine that acts as an artificial heart and lung during surgery), and death. Participants will be randomised to receive oxygen plus nitric oxide (intervention arm) or oxygen without nitric oxide (control arm) during CPB.
Cardiac denervation is inherent to the arterial switch (ASO) technique for the repair of transposition of the great arteries (TGA) and the long term reinnervation process has not been studied. We sought to describe the reinnervation status of adult patients long after the ASO, to identify areas of myocardial perfusion/innervation mismatch and to assess the relation of innervation status and exercise capacity.
The investigators proposed to review the exercise tolerance, cardiac function, and quality of life in patients born with transposition of the great arteries that have undergone surgery with either the Mustard or Senning procedure. Participants will complete a questionnaire. The investigators will review the participants' recent cardiac function testing which will assess their current health status. These tests include an echocardiogram, a metabolic exercise stress test, cardiac imaging, and a 24-hour Holter monitor. This collection of testing results will be compared specifically with previously acquired data during the first phases of this study (published in 2001 and 2007).
In the landmark Boston Circulatory Arrest Study, neurologic and developmental status was measured following infant heart surgery and then prospectively at ages 1, 2.5, 4, 8, and 16 years, with findings of significant neurocognitive deficits and brain MRI abnormalities regardless of operative management. To date, no study has evaluated the neuropsychological and neuroimaging antecedents and correlates of well-being in adults with congenital heart disease, a population now >1 million and projected to grow at 5% per year. The investigators propose to study the Boston cohort at ages 24-29 years to assess the associations of adult well-being with childhood and adolescent executive function, other measures of mental health and cognitive function, adolescent brain MRI findings, and clinical variables; findings will guide the design of interventions in childhood to optimize outcomes in adults with congenital heart disease.
This study assesses in a double-blind, randomized, placebo-controlled multi-center pilot trial the effect of PDE-5 inhibition with Tadalafil on right ventricle size and function, exercise capacity and neurohumoral activation in adults with congenital heart disease and a right ventricle in subaortic position over a 3-year follow-up period.
The purpose of the Oxy-CAHN study is to improve the monitoring capabilities of newborn infants recovering from congenital heart surgery. Currently, we utilize important but unsophisticated measures, such as vital signs and lactate measurements, to monitor these patients. Although they are useful in categorizing patients as well or unwell, these signs currently lack the power quantify a patient's risk for cardiac arrest. More to the point, they are mostly indirect measures of what we really are assessing, which is tissue oxygen delivery. Our group has significant expertise with devices which quantify the amount of oxygen that a baby consumes every minute. Historically, these values are more commonly used in combination with other measures to assess nutritional and metabolism status. In critically ill patients, however, the volume of oxygen consumed by a patient may be limited by the amount of oxygen their circulation delivers. This may represent a critical relationship, which has been previously described, but not exploited for the purpose of identifying patients with critically low oxygen delivery. The aims of this study are therefore (1) to demonstrate that oxygen consumption can be safely and precisely measured continuously in newborns undergoing one of two common congenital heart surgeries, (2) to determine whether postoperative circulatory failure is associated with a precedent change in oxygen consumption, and (3) to determine whether the addition of the oxygen-based measurements (including oxygen consumption and venous oxygen saturations) to standardly measured parameters will add power in predicting which patients will experience postoperative circulatory failure. If successful, this study may improve our capacity to non-invasively and continuously monitor patients following the highest risk congenital heart surgeries, and in the future,to create an algorithm which quantifies a patients risk for having a cardiac arrest. This may permit providers to intervene on these patients earlier, improving the morbidity and mortality associated with congenital heart disease.
