NCT ID: NCT05199857 Recruiting - Frailty Clinical Trials

WE BEAT - HEART Club Fontan Wellness Project: A Virtual Resilience Promotion and Frailty Prevention Program

Start date: March 30, 2022
Phase: N/A
Study type: Interventional

This trial is being conducted to evaluate the effect of a small-group wellness education program combined with a longitudinal, individualized prescription exercise program on the wellness, resiliency, and daily activity levels of pediatric patients with Fontan physiology. There will be two phases for this project. The first phase is the "WE BEAT Group Wellness Education Program" and participants will be transitioned into the phase two HEART Club following phase one. The trial will look at feasibility and acceptability of the program. Additional hypothesis include home whether exercise interventions can: - be delivered without any associated serious cardiac events; - will result in a decreased proportion of patients who are categorized as frail when compared to the cohort's pre-test baseline. - will result in increased measured peak oxygen consumption when compared with their pre-intervention baseline. - will result in increased step counts measured monthly from baseline to end of intervention - will improve self-reported quality of life from baseline to post-intervention. - will result in increased patient reported activity level from baseline to post-intervention

NCT ID: NCT05034354 Recruiting - Heart Failure Clinical Trials

Virtual Remote Physiological Monitoring Program of Children With Heart Disease

Start date: February 8, 2022
Phase: N/A
Study type: Interventional

Infants and children with heart conditions require treatment in children's hospitals that are typically located in large cities. This creates challenges for children and families who need to travel long distances to come to appointments. Providing quality care to children with heart disease has further been challenged by the COVID-19 pandemic, with a shift towards decreased in-person contact and an increase in virtual visits, where assessment by doctors and nurses is more limited. This research study will look at how families of children with heart disease access care and how investigators can improve care with virtual technologies. This will involve testing a new home-based virtual care platform that uses Bluetooth technology to connect weight scales, oxygen measuring devices and blood pressure cuffs with a smartphone app, allowing parents to easily use these devices and send accurate data directly to the cardiology team. Investigators will obtain feedback from families, patients, and healthcare providers about how this helped or did not help them, and adjust the technology as needed to make it better.

NCT ID: NCT04901975 Recruiting - Single-ventricle Clinical Trials

Fibrosis and the Fontan

Start date: February 11, 2021
Phase: Phase 1/Phase 2
Study type: Interventional

The purpose of this study is to non-invasively characterize the fibrotic consequences of single ventricle physiology, its possible solution and effect on lymphatics. This project investigates the response to acute imposition of Fontan hemodynamics by examining the interrelationship between liver and cardiac fibrosis/dysfunction and lymphatic congestion along with a pilot trial of the antifibrotic agent, spironolactone, to prevent these consequences and to determine if MRI can discern these differences. The combination of serum biomarkers and MRI form a powerful non-invasive tool in putting together this complicated web of dysfunction.

Phase:
Study type: Observational [Patient Registry]

The purpose of the study is to monitor the clinical safety and performance of the EXCOR Venous Cannula in context of an EXCOR VAD therapy to ensure continued acceptability of identified risks, to enable detecting emerging risks and to assess clinical improvement on both short- and long-term.

NCT ID: NCT04581668 Recruiting - Clinical trials for Heart Defects, Congenital

Impact of NAVA Ventilation on Brain Oxygenation and Perfusion in Children With Congenital Heart Disease

Start date: October 5, 2020
Phase: N/A
Study type: Interventional

Positive intra-thoracic pressures induced by mechanical ventilation can negatively impact right heart hemodynamics by restricting systemic venous return and increasing right ventricular afterload. These consequences may be detrimental in patients with a restrictive right ventricular physiology and in patients with single ventricle physiology. NAVA (Neurally Adjusted Ventilatory Assist) ventilation decreases intra thoracic pressures compared to conventional ventilation modes. Brain perfusion is both a hemodynamic indicator and a prognostic factor in cardiac postoperative care. Diffuse Correlation Spectroscopy (DCS) coupled with Near Infrared Spectroscopy (NIRS) is a new technology that allows monitoring, in addition to brain tissue oxygenation, changes in brain blood flow. This physiological study aims to evaluate the impact of NAVA mode ventilation on cerebral and systemic hemodynamics in post-operative cardiac surgery patients with preload dependant right ventricle or with passive venous return to the lungs . This prospective cross-over study will include 30 patients. Once stabilized in intensive care, patients will undergo 2 periods of ventilation in NAVA mode and conventional mode separated by a 30-minute washout period, in a random order. For each period the following information will be collected: changes in cerebral blood flow and cerebral oxygenation, hemodynamic parameters including cardiac output and oxygen transport and ventilatory parameters.

NCT ID: NCT04195451 Recruiting - Single-ventricle Clinical Trials

Re-Energize Fontan

Start date: August 6, 2020
Phase: N/A
Study type: Interventional

Survival of children with single ventricles ("half a heart") beyond the neonatal period has increased dramatically with the staged Fontan palliation. Yet, long-term morbidity remains high. By the age of 40, 50% of Fontan patients will have died or undergone heart transplantation. With >1,000 Fontan palliations performed in the US annually, there is a burgeoning population of Fontan patients at risk for progressive heart failure and death. Factors that contribute to onset and progression of heart failure in Fontan patients remain incompletely understood. However, it is established that Fontan patients have poor exercise capacity, associated with a greater risk of morbidity and mortality, in addition to decreased muscle mass, abnormal muscle function, and endothelial dysfunction contributing to disease progression. In adult patients with two ventricles and heart failure, reduced exercise capacity, muscle mass, and muscle strength are powerful predictors of poor outcomes, and exercise interventions can not only improve exercise capacity and muscle mass, but also reverse endothelial dysfunction. Limited exercise interventions in children with congenital heart disease have demonstrated that exercise is safe and effective; however, these studies have been conducted in small, heterogeneous groups, and most had few Fontan patients. Furthermore, none of these interventions have studied the impact of exercise on muscle mass or mitochondrial function, or endothelial function. The investigators propose a milestone-driven, randomized controlled trial in pediatric Fontan patients to test the hypothesis that a live-video-supervised exercise (aerobic + resistance) intervention will improve cardiac and physical capacity; muscle mass, strength and function; and endothelial function. The investigators' ultimate goal is the translation of this model to clinical application as an "exercise prescription" to intervene early in pediatric Fontan patients and decrease long-term morbidity and mortality.

NCT ID: NCT04106479 Recruiting - Tetralogy of Fallot Clinical Trials

NIRS in Congenital Heart Defects - Correlation With Echocardiography

Start date: October 11, 2019
Phase:
Study type: Observational

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.
