  • Developing a Digital Aid to Improve ICD Decisions

    open to eligible people ages 60 years and up

    Advanced heart failure, affecting 7 million Americans, has multiple causes and results in greatly increased risk of disability and death. A major problem is sudden cardiac death, when the damaged heart develops an abnormal pattern of electrical conduction that can result in cessation of heart activity. While placement of an Implantable Cardioverter-Defibrillator (ICD) in a patient's chest can help prevent sudden cardiac death, these devices have several important downsides. This protocol focuses on development of a digital decision aid that helps heart failure patients make informed decisions that balance the benefits and downsides of ICD placement. This protocol covers the use of participant surveys, focus groups, and interviews to obtain the needed background information to guide the development of this digital tool, which will be subsequently tested against usual care in a randomized clinical trial. The study design is best described as a mixed methods evaluation and refinement of a digital app to improve ICD decision-making. In the future, the present protocol will be modified to create a new protocol that covers the needed human subjects requirements for performance of this clinical trial.

  • Clinical Diagnostic Test for CRDS

    open to all eligible people

    Calcium Release Deficiency Syndrome (CRDS) is a novel inherited arrhythmia syndrome secondary to RyR2 loss-of-function that confers a risk of sudden cardiac death. Diagnosis of CRDS presently requires cellular-based in vitro confirmation that an RyR2 variant causes loss-of-function. We hypothesize that CRDS can be diagnosed clinically through evaluation of the repolarization response to brief tachycardia, mediated by cardiac pacing, and a subsequent pause.

  • PRIMARY Ancillary Substudy

    open to eligible people ages 60 years and up

    The PRIMARY trial (NCT05051033), which compares mitral valve repair (MVr) to transcatheter-edge-to-edge-repair (TEER), offers a platform for conducting mechanistic studies to develop early insights into the pathophysiological processes by which mitral valve prolapse (MVP) can impact left ventricular (LV) myocardial structure and function, and, thereby, predispose to arrhythmias and sudden death. Such insights are key to identifying interventions to reduce the long-term sequelae of heart failure (HF) and arrhythmias, as well as delineate optimal therapeutic approaches for different patient sub-groups.

  • Human/Machine Interface: What the HeartMate 3 ® Device Tells Us About the Future

    open to eligible people ages 18-100

    Durable left ventricular assist devices (dLVAD) have been increasingly utilized since the mid to late 1990s, with an uptick of utility starting in 2010 following expanded indications for therapy to not only include a bridge to transplantation strategy, but also for those individuals who suffer from advanced heart failure (HF) and do not qualify for cardiac transplantation. Despite the decreasing size of the newest generation devices leading to a lessened occurrence of adverse events, bleeding and infection still remain a concern for clinicians, as well as a general lack of predictability towards adverse events in individuals with a dLVAD in place. There is a lack of description in the literature currently, regarding the interface between what the pump data provides and what is seen in clinical practice. There also is little known about the effects of what is provided in the pump data, in correlation to quality-of-life following dLVAD implantation. Therefore, the purpose of this study is to prospectively analyze normal and abnormal pump data through pump operations such as suction events, low flow alarms as well as other adventitious alarms, PI events and power cable disconnects greater than 20 seconds, from the HeartMate 3 ® dLVAD in order to clinically correlate this data to quality of life, frailty and other various medical conditions and adverse events as defined by the Interagency Registry for Mechanically Assisted Circulatory Support (Intermacs). This will be achieved through two aims: 1) Evaluate the effectiveness of dLVAD pump operations data on clinical practice application (quality of life, frailty and various medical conditions, and adverse events such as GIB, RHF, infection, hypertension, arrhythmias and stroke); and 2) Evaluate correlations and relationships of longitudinal normal and abnormal dLVAD pump operations data, to demographic and clinical variables. This study is the first study to evaluate HeartMate 3 ® dLVAD pump operations data over time for effectiveness in the clinical practice.

  • Pharmacodynamics, and Safety Profile of Understudied Drugs Administered to Children Per Standard of Care (POPS)

    open to eligible people ages 0-20

    The study investigators are interested in learning more about how drugs, that are given to children by their health care provider, act in the bodies of children and young adults in hopes to find the most safe and effective dose for children. The primary objective of this study is to evaluate the PK of understudied drugs currently being administered to children per SOC as prescribed by their treating provider.

  • Sustained Auricular Nerve Stimulation for PVC Suppression

    Sorry, accepting new patients by invitation only

    Non-invasive vagus nerve stimulation has been clinically tested for the treatment cardiac arrhythmias. However, prior studies have shown mixed results-possibly in part due to inadequate stimulation duration. Therefore, we have designed an investigator-initiated early feasibility study to evaluate safety, tolerability, and compliance with prolonged, nocturnal auricular nerve stimulation using the Parasym device.

  • MARY-JANE Cannabis and Heart Rhythm Trial

    Sorry, in progress, not accepting new patients

    Despite recreational cannabis now being legal in 23 states, where more than 100 million Americans reside, studies on the actual health effects are limited. This study is a randomized trial, where each participant will be instructed to consume or avoid cannabis on randomly assigned days during a 14-day monitoring period. The goal of this study is to answer the question: "Does cannabis use increase the frequency of 'early' and abnormal heart beats?" During the 14-day period, participants will wear an external heart monitor, a glucose monitor, and a fitness tracker to track heart rhythm, glucose levels, step counts, and sleep health. Participants will use a mobile app or a text messaging service for daily instructions/reminders on cannabis use, and short surveys. The investigators ask that participants smoke or vape cannabis at least once on days they are instructed to consume cannabis. Compelling evidence of heart and other health effects would be important to the clinical care of our patients.

  • ATrial Tachycardia PAcing Therapy in Congenital Heart

    Sorry, not currently recruiting here

    Congenital heart disease (CHD) affects approximately 1% of newborns in the US, with 25% of those affected having critical conditions requiring open heart surgery within one year of birth. Surgical and medical advances have allowed many patients to live beyond their fourth and fifth decades of life. Unfortunately, cardiac arrhythmias are a relatively common sequela due to cardiac anomalies and surgical scars in addition to residual volume and pressure load on the heart. Atrial arrhythmias, including sinus node dysfunction and intra-atrial re-entrant tachycardia (IART) are among the more common abnormalities found in adults with repaired CHD. The presence of IART significantly increases morbidity and mortality, and anti-arrhythmic medications have been shown to be a sub-optimal treatment strategy with the majority of patients requiring multi-drug therapy. Catheter ablation procedures remain a treatment option, but are less successful for some patient demographics. In the mid-1990's, pacemakers with atrial anti-tachycardia pacing (ATP) capabilities were developed, primarily for the management of atrial flutter and fibrillation in adults with structurally normal hearts. Given the need for pacemakers in the CHD population to manage sinus node dysfunction and atrioventricular node conduction block, the adoption of atrial anti-tachycardia pacemakers began to gain favor. However, there is limited data available comparing the safety and effectiveness of ATP therapy between various demographics of CHD patients. In the current study, the investigators aim to determine if ATP is an effective treatment strategy for IART, specifically within particular sub-populations of CHD patients. Additionally, investigators hope to delineate any significant differences in efficacy of ATP treatment between adult and pediatric congenital heart patients. The research team will accomplish our goals with a retrospective, multi-center study in which data is collected from existing electronic medical records and pacemaker interrogations. Following data collection, the investigators will employ statistical analyses to determine if certain CHD demographics are statistically significant predictors of ATP therapy outcomes. The purpose of this prospective/retrospective study is to determine how effective atrial anti-tachycardia therapies are with the congenital heart patients who are known to have atrial arrhythmias. As this population ages, we know that arrhythmic burden increases and medications are increased or changed for symptomatic improvement. Patients will be enrolled at the time of anti tachycardia device (ATD) placement or when device therapies are turned on. Patients will need a minimum of 5 years of clinical history prior to implantation and after implantation (unless patient is very young). Data will be collected both retrospectively and prospectively. The research team will consent patients at the time of clinical evaluations and scheduled follow-ups (usually 3 - 6 months). If therapy is effective, investigators will determine the specific programming which was successful. If therapy was ineffective, investigators will also determine if a change in programing was made and if this improved ATP efficacy. Investigators will also determine the arrhythmia burden. Cardioversion and medications before and after ATD implantation will be the key determinants of arrhythmia burden in this study.
