Active clinical trials for "Heart Diseases"

The goal of this observational study is to learn about the changing over the time of transseptal (TSP) catheterization for catheter ablation of arrhythmias in the left heart. This study aims to investigate if auxiliary tools for TSP catheterization improved the safety and efficacy.

The goal of this observational study is to learn about in STEMI with Primary PCI Patients. The main questions it aims to answer are: To determine the value of AMR in predicting the long-term clinical prognosis of patients with STEMI after PPCI, and to find the best cut-off value. Analyze the factors of PPCI affecting AMR and explore the effective measures of PPCI microcirculation protection. Radiographic images of STEMI receiving primary PCI treatment in several chest pain centers in China will be included. The last image of the infarct-related vessel will be used as a target to calculate its AMR. The relationship between AMR and long-term clinical prognosis was analyzed.

This case-control study is planned to recruit patients who meet the enrollment conditions, receive cardiac surgery (cardiac valve surgery or coronary artery bypass surgery) and cardiopulmonary bypass, and sign the informed consent form in the second ward of adult cardiac surgery, Fuwai Hospital. Use RASS, CAM-ICU scales to evaluate postoperative patients and divide them into delirium and non-delirium groups according to whether they had delirium after surgery. There will be 30 patients in each group. Match the two groups in terms of surgical type, duration of cardiopulmonary bypass, gender and age range (± 3 years). Collect and record the preoperative, intraoperative and postoperative data of the enrolled patients, including cardiopulmonary bypass time, ICU stay time, length of mechanical ventilation, hemodynamics and other data. Fecal and/or blood samples are collected from 60 patients before, immediately after and after operation. The laboratory test and analysis shall be started after the collection of clinical samples. Fecal samples are used for Metagenomics Sequencing and Functional genomics. Blood samples are analyzed by serum metabolomics for changes in intestinal metabolites entering the blood circulation. Simultaneous measurement of IL-6 and TNF in peripheral blood with serum samples- α, IL-1a,IFN-γ and LPS, D-lactic acid and diamine oxidase levels.Use Multi-omics approach to analyze the correlation between intestinal flora diversity, functional gene abundance and blood metabolites, inflammation level and intestinal barrier function, and to find the clinical evidence of the correlation between microbiota-gut-brain axis and the occurrence of POD in patients. Through comprehensive analysis of the research results of this experiment, access to literature, write papers, submit papers and publish relevant papers.

Regent China Post-Market Clinical Follow-Up (RC-PMCF): this clinical study is to confirm the safety and performance of Abbott's Regent MHV for replacement of native or prosthetic aortic valves in a Chinese population.

Introduction: The use of a nutritional protocols provides the standardization of assessment procedures and the optimization of nutritional status recovery of pre-surgical infants with Congenital Heart Disease (CHD). However, to our knowledge there are no validated instrument for presurgical nutritional support for infants with congenital heart disease (CHD) in Brazil. Objective: Assess the clinical effectiveness of the translated and cross-culturally adapted protocol, Nutritional Pathway for Infants with Congenital Heart Disease before Surgery (Marino et al., 2018), on the weight change of infants with congenital heart disease in two specialized cardiology hospitals in Southern Brazil in partnership with the UK research group that authored the original of protocol. Methods: A randomized, pragmatic clinical trial will be carried out. The sample will consist of children with CHD, between 0-12 months of age, awaiting cardiovascular corrective surgery from the Pediatric Outpatient Clinic in the Institute of Cardiology (IC) and Children's Hospital Santo Antonio of Santa Casa de Misericordia. The previously translated pre-surgical nutritional intervention protocol for infants with congenital heart disease will be compared with current routine nutritional guidelines used in the follow-up services of children with congenital heart disease in these institutions within the national public healthcare, SUS. Intended results: It is expected that the culturally-adapted pre-surgical nutritional support protocol for children with congenital heart disease will be effective in pre-surgical infant weight gain, which will likely improve surgical prognosis and clinical outcomes. And we hope that this protocol will promote the standardization of care, and will provide an empirically-based nutritional intervention that may improve the effectiveness of nutritional recovery in the CHD infants. Furthermore, the results may be used in the formulation of Brazilian guidelines for comprehensive care of children with congenital heart disease.

This research focuses on the development and validation of indicators on the appropriateness of oral anticoagulant prescriptions. The investigators want to propose transferable tools to other healthcare institutions to allow automated construction of indicators as part of a structured approach to improve future practices. The main objective of the study is to develop indicators on the appropriateness of oral anticoagulant prescriptions in adult medicine automated from the hospital information system and to assess their criterion validity.

Establish a cardiovascular biomarker profile to help screening for congenital heart disease in infants and children as well as use non-invasive cardiac imaging in combination with such profiling to better predict the need for future cardiac interventions such as open heart surgery or cardiac catheter intervention selected types of with congenital heart disease.

Single-stent strategy with provisional approach represents the gold standard for percutaneous coronary intervention of bifurcation lesions, and, according to European Bifurcation Club, performing provisional approach presents two steps considered as mandatory: "crossover stenting" in main vessel (MV) and subsequent post-dilation or "POT" (proximal optimization technique). While consensus exists regarding these first two steps, the exact optimal following sequence in case of side branch (SB) jeopardize after main vessel stenting is still a matter of debate. Actually, the two most used techniques in this setting are represented by the simultaneous inflation of two balloons located respectively in the MV and SB followed by a second POT (POT/kissing balloon/POT technique) and the isolated inflation of a balloon placed in the SB followed by a second POT (POT/SIDE/POT technique). The objective of this study is to compare the configuration achieved with POT/KISS/POT (PKP) and POT/SIDE/POT (PSP), using the "cutting edge" high-resolution intracoronary imaging modality (Optical Coherence Tomography, OCT).

The purpose of this study is to determine if a partial heart transplantation in patients with congenital heart disease is safe and feasible. Participants will have a partial heart transplant involving surgical replacement of the pulmonary valve with the heart valve and supporting blood vessels from an organ donor. The procedure, tests, medications, and follow-up visits will all be done per standard of care. Medical data will be collected to look at outcomes after surgery.

IntelliStent is intended to achieve reduction of pulmonary hypertension, improvements in symptoms and quality of life in adolescent and adult patients with congenital heart disease and dilated cardiomyopathy.
