Filter by:The goal of this clinical trial is to compare the effect of high-calorie density formula (HDF) and standard formula (SF) in infants with congenital heart surgery. The main questions it aims to answer are: 1. Is there any difference in nutritional status between both groups after 3 months? 2. Is there any difference in calorie intake per day between both groups during hospitalization? 3. Is there any difference in clinical outcomes (mortality, duration of using mechanical ventilation, length of stay, and events of side effects) between both groups? A group of participants will be given HDF (1 kcal/ml) from enrollment until three months. Researchers will compare them to the group of participants who are given SF (0.67 kcal/ml) to see if there is any difference in nutritional status, calorie intake, and other clinical outcomes between the two groups.
To evaluate the association of surem TRAF3IP2 levels with the atherosclerotic plaque development in human
Follow-up of patients with complex congenital heart disease (CHD) usually involves ultrasound imaging or even MRI or CT scans of the heart and stress testing. But these examinations can be challenged in terms of their sensitivity. Thus, the development of non-invasive jugular venous and radial arterial pressure sensors, reflecting the hemodynamic function of the right heart, would be very useful to the clinician responsible for early detection of a deficit in right ventricular function.
Research hypothesis - Recent studies have shown that high-dimensional descriptors of the cardiac function can be efficiently exploited to characterize targeted pathologies. In this project, the investigators hypothesize that echocardiograms possess a wealth of information that is currently under-exploited and that, combined with relevant patient data, will allow the development of robust and accurate digital tools for etiological diagnosis. Objectives - Based on key advances recently obtained in image analysis, notably by members of the consortium, the objective of this project is to develop rigorous and explainable cardiac disease prediction models from echocardiography based on the transformer paradigm (AI). The strength of this study lies in the development of a strong AI framework to model the complex interactions between high-quality image-based measurements extracted from echocardiograms and relevant patient data to automatically predict etiological diagnosis of cardiac diseases
Although the incidence of delirium after cardiac surgery is high, it is not sufficiently recognized. The long-term effects of delirium are likely to be underestimated. In this study, the investigators aimed to examine the relationship between optic nerve sheath diameter and postoperative delirium in open hearth surgery.
To investigate and evaluate the capacity of prenatal screening, diagnosis and counseling of congenital heart disease in medical institutions in China, in order to understand the current status and existing problems of prenatal prevention and treatment capacity of congenital heart disease in China, and to obtain corresponding baseline data, so as to provide scientific basis for further improving prenatal screening and diagnosis policies in China.
Drug-eluting stents (DES) have long been recommended as the default device for patients undergoing percutaneous coronary intervention (PCI). Drug-Coated Balloon (DCB) angioplasty is similar to plain old balloon angioplasty procedurally, but there is an anti-proliferative medication paclitaxel-coated on the balloon. DCB angioplasty has the following advantages compared to DES implantation: Firstly, the drug in DCB is uniformly distributed and released, whereas the drug release of DES via the stent platform is uneven -85% of the vascular wall is not covered by the stent strut. Secondly, there is no alloy in the vessel after DCB angioplasty, while the coronary stent platform and polymer might cause temporal or persistent inflammatory response leading to intimal hyperplasia. Finally, there is no metal cage restraining vessel motion after DCB, and the physiological function of coronary arteries would be maintained. Currently, DCB constitutes an important treatment option in ISR, which is endorsed by the 2018 European Society of Cardiology Guidelines on myocardial revascularization. In addition, some interventional cardiologist has also applied DCB in de novo lesions in their clinical practice. Diabetes is associated with worse outcomes after coronary revascularization and has been identified as an independent predictor of adverse events in patients with cardiovascular disease. Although some small sample size RCTs and observational studies have suggested that the clinical prognosis of DCB is non-inferior to the drug-eluting stent (DES), there is still a lack of evidence comparing the DCB versus DES for de novo or ISR coronary lesions in diabetic patients. The current study aims to compare the long-term efficacy of DCB to DES in de novo or ISR coronary lesions in diabetic patients.
Functional tricuspid regurgitation (FTR) remains a common finding in patients with left-sided valvular heart diseases especially mitral valve regurgitation or stenosis. It is mainly caused by dilatation and flattening of the tricuspid valve (TV) annulus as a result of right ventricular (RV) enlargement and is inevitably affected by the RV function. Multiple studies support the better outcome of using rigid ring annuloplasty over suture repair for treating FTR in concern with the durability and freedom from residual regurgitation. These studies refer the superiority of rigid ring annloplasty to the three-dimensional configuration achieved by such rings which matches the normal tricuspid annulus and, at the same time, to the rigid support of the annulus. On the other hand, other studies support the use of flexible prosthetic bands like Dacron or polytetrafluroethilin (PTFE), especially over suture techniques, due to their easy applicability and availability with good postoperative results. Therefore, suture annyloplasty became nowadays less convenient for FTR repair since both flexible bands and rigid rings appeared to offer good midterm outcomes in recent meta-analysis studies. However, the ideal annuloplasty method for repairing FTR is still debatable between the three-dimensional (3D) rigid rings versus flexible prosthetic bands. In this retrospective comparative study, we share our experience with flexible fashioned bands in FTR.
The goal is to compare patients with and without varying severity of pulmonary vascular disease based upon hemodynamic signatures, echocardiographic measures, and lung ultrasound, in tandem with expired gas metabolic testing and blood sampling.
Background: The Fontan operation has been used to treat complex cardiac anomalies with a single-functioning ventricle. A study performed by Instituto do Coracão-Hospital das Clínicas-Universidade de Sao Paulo (InCor/HCFMUSP)-Brazil, Hospital das Clínicas of Ribeirão Preto-Brazil, department of the University of Aarhus, and Rigshospitalet, Denmark demonstrated an impairment peripheral lymphatic function in Fontan patients compared with healthy controls. However, the ability to increase the frequency of contractions is impaired when stressed by hyperthermia. Lymph vessels in Fontan patients were unable to respond usually. The participants were only able to increase the frequency of contraction twice during stress, compared to a five-fold increase among healthy controls. At the microcirculation level, Fontan patients filtered less fluid into the capillaries interstitial space than healthy controls at venous occlusion pressure. Studies carried out at InCor/HCFMUSP demonstrated that supervised aerobic exercise training improves the functional capacity and neurovascular control in Fontan patients compared to the non-training control group. However, the effect of aerobic exercise and light muscle resistance performed through online rehabilitation has not yet been demonstrated in peripheral lymphatic function and microcirculation. Aim: Evaluate the effects of an aerobic and light muscle resistance exercise program on peripheral lymphatic function, capillary filtration, functional capacity, and quality of life in adults with Fontan circulation. Methods: The function of the superficial lymphatic vessels in the lower leg will be investigated during rest in supine and standing positions, using near-infrared fluorescence imaging using Indocyanine Green (ICG; Verdye, Diagnostic Green GmbH, Germany). The variables analyzed are contraction frequency (contraction/minute), pumping Pressure (mmHg), and packet velocity. Venous congestion plethysmography will perform to analyze the capillary filtration and cardiopulmonary exercise test for functional capacity. The quality of life will be evaluated using the SF-36 Short-Form questionnaire. Expected results: the physical training improves peripheral lymphatic function, capillary filtration, functional capacity, and quality of life in patients with biventricular compared to the control group (no exercise training)
