NCT03089398
The purpose of the study is to learn which treatment option is better for patients who have multi-vessel coronary artery disease (blockages in more than one vessel supplying blood to the heart muscle). The treatment options this study will compare are: (1) Hybrid Coronary Revascularization \[HCR\] (a combination of surgery and catheter procedures to open up clogged heart arteries) and (2) Percutaneous Coronary Intervention \[PCI\] (catheter procedures alone to open up clogged heart arteries). There are no new or "experimental" procedures being tested in this study: both HCR and PCI are well-established procedures and are regularly performed in patients who have coronary artery disease. But, the FDA has not approved the drug-eluting stents used in PCI for all types of coronary artery disease. We have received an Investigational Device Exemption from the FDA to use the drug-eluting stents in this trial in the same way that they are used in clinical practice. The study being proposed here will use rigorous scientific methods and should result in a very high level of certainty about which procedure is best for patients with coronary artery disease.
NCT02922036
This study is a prospective, multi-center, pivotal trial to study the safety and efficacy of the WiSE-CRT System for Cardiac Re-synchronization Therapy.
NCT06645327
To investigate the superior vena cava collapsibility index (SVC-CI), measured via transesophageal echocardiography (TEE), as a marker of fluid responsiveness. Two groups will be compared in this study. Groups will be identified by obtaining cardiac output (CO) by standard means using the TEE or pulmonary arterial catheter (PAC). Both of these monitors are considered standard for patient's undergoing coronary artery bypass grafting surgery (CABG) and recording initial CO readings. Based on CO, the patient's will be placed in study groups one or two. Participants with normal and mildly reduced left ventricular ejection fraction (LVEF \>40%) for group one and those with moderately to severely reduced LVEF (\<40%) in the second group. Following group separation, we will measure the SVC-CI and CO metric in both groups. The intervention will be an operating room table tilt test (head up and then head down) to artificially simulate giving the patient additional fluid. Before and after table tilt, the SVC-CI and CO will be obtained and measured. The SVC-CI is a mathematical equation determined by distance measurements taken via TEE to identify how much the superior vena cava has collapsed following table tilt. Participants will be considered responders if the CO increases by 12% following intervention. Non responders less than 12% change in CO following intervention. Our hypothesis is that the SVC-CI can differentiate responders vs non-responders with regards to fluid responsiveness with adequate sensitivity and specificity in participants with CAD undergoing isolated CABG. The SVC-CI numerical values for the two groups, responders and non-responders, will calculate a threshold of sensitivity and specificity percentages for future patients undergoing CABG.
NCT04141605
The primary objective of this study is to collect real-world clinical performance data to assess the clinical outcomes of patients receiving heart transplants using donor hearts transported via the SherpaPak CTS System. These results will be compared to outcomes of retrospective patients whose hearts were transported with the previous standard method.
NCT03880838
The researchers' mission is to promote healthier eating behavior and to reduce costs associated with healthcare. The purpose of this study is to evaluate the effects of mailing randomly selected participants a letter promoting a plant-based diet. Depending on the experimental condition, participants may additionally receive a free documentary, Forks Over Knives, and they may also get letters which use commitment- or prevention-focused messages to encourage watching the documentary and changing their eating behavior. The researchers hypothesize that receiving the documentary will be associated with lower insurance claims and improved health outcomes one and two years later. The researchers also hypothesize that using either commitment- or prevention-focused messages will also contribute to lower insurance claims and improved health outcomes compared to experimental conditions where materials did not include these messages. This study will help the researchers design evidence-supported programs that can improve people's health.
NCT06445608
This purpose of this trial is to demonstrate 30 day safety and effectiveness outcomes of the KARDION CORY P4 System in subjects who require hemodynamic support during a high-risk PCI procedure.
NCT03657459
Lack of recognition of HF danger signs and lack of understanding of how to control and minimize danger signs could lead to their escalation and prompt all-cause and HF-related health care resource utilization (HCRU). Investigators hypothesize that patients must understand HF danger signs to have self-confidence in recognizing them and in taking steps to minimize or eliminate their occurrence post hospital discharge. Investigators will determine if video education in HF danger signs recognition and control prior to discharge (and post-discharge) reduces all-cause and HF-related HCRU.
NCT04905290
The purpose of the CSPOT study is to determine the best mode of cardiac resynchronization therapy (CRT) pacing for different populations of CRT patients, comparing traditional biventricular or left ventricular pacing (BiV), conduction system pacing (CSP)-only, and conduction system pacing optimized therapy (CSPOT) also known as a combination of conduction system pacing (CSP) and left ventricular (LV) pacing. Additionally, safety of the system will be assessed.
NCT04737265
Investigators will evaluate the safety and feasibility of a biomarker-guided cardioprotection strategy using NTproBNP, as compared to usual care, in breast cancer and lymphoma patients treated with anthracyclines.
NCT03066050
This study is a continuation of two previous studies --- the Severe Ischemic Mitral Regurgitation (SMR) Trial (NCT00807040) and the Moderate Ischemic Mitral regurgitation (MMR) Trial (NCT00806988) --- to learn more about patients' health 5-10 years after their mitral valve surgeries. The investigators will collect long-term health information on SMR and MMR trial participants using electronic medical records, patient and/or family input, public records, and healthcare- and vital status-related databases.
NCT03341156
This study is comparing the use of Kcentra vs. standard transfusion in patients undergoing heart transplantation surgery. Half of the patients will receive Kcentra, while the other half will receive fresh frozen plasma.
NCT04907526
Researchers want to better understand what happens to the heart when the autologous (from one's own body) stem cells are injected directly into muscle of the right side of the heart during the Fontan (Stage III) surgery. They want to see if there are changes in the electrical activity, the structure, and the function of the heart following this stem cell-based therapy. Researchers will compare the results from people who receive the stem cells to the results from people who do not receive the stem cells.
NCT04591392
Evaluation of the safety and efficacy of the reSept ASD Occluder to treat patients with clinically significant secundum atrial septal defect
NCT05100836
A multi-center, prospective \& retrospective, observational single-arm study of the clinical outcomes up to one year collected from electronic health records of patients which have undergone standard of care implantation of Impella 5.5, regardless of clinical situation or indication. All patients will be enrolled via an IRB-approved Waiver of Informed Consent and HIPAA Authorization. All patients who were supported retrospectively (prior to site IRB approval) with Impella 5.5 at the investigative site will be entered into the SURPASS registry and specified as the retrospective cohort.
NCT06212466
A prospective, multicenter, observational, single-arm trial to validate CardioFlux MCG's ability to diagnose myocardial ischemia caused by coronary microvascular dysfunction in patients with suspected ischemia and confirmed no obstructive coronary artery disease (suspected INOCA) by using diagnostic measures of coronary flow reserve (CFR) via invasive angiography as a reference standard for diagnosis.
NCT06062329
Evaluation of the Safety and Efficacy of the Symphony Thrombectomy System in the Treatment of Pulmonary Embolism
NCT05428384
The investigation will enroll subjects who have been previously implanted with the CardioMEMS™ Pulmonary Artery Sensor. This clinical investigation is twofold; in the first phase (development phase) data collected will be used to complete development of an algorithm that can estimate cardiac output from CardioMEMS™ Heart Failure (HF) System readings. The second phase (validation phase) of this clinical investigation is intended to compare the Cardiac Output estimate from CardioMEMS HF System to Cardiac Output estimates from Cardiac Magnetic Resonance Imaging (reference standard).
NCT00853632
The purpose of the study is to demonstrate the long term safety and effectiveness of the Carpentier-Edwards® PERIMOUNT Magna Mitral Valves in patients undergoing mitral valve replacement with or without concomitant procedures requiring cardiopulmonary bypass.
NCT06526988
An increasing number of guideline-directed medical therapies (GDMT) have been developed for patients with chronic heart failure with reduced ejection fraction (HFrEF). When used in combination at recommended doses, patients often experience significant improvements in cardiac function, quality of life, and survival.1,2 However, GDMT underuse occurs for the vast majority of patients with HFrEF. Two recent trials demonstrated improved GDMT prescribing during a clinic visit, each using automated delivery of a patient-centered decision support tool to promote a proactive and holistic approach to prescribing: EPIC-HF (NCT03334188) tested a brief video and checklist document sent to patients just prior to a clinic visit encouraging them to work with their clinicians to make at least 1 positive change to their GDMT; PROMPT-HF (NCT05433220) tested tailored electronic health record (EHR) alerts for GDMT intensification delivered to clinicians during clinic visits. The current I-I-CAPTAIN-HF study aims to broadly implement and test the EPIC-HF patient-facing and PROMPT-HF clinician-facing tools for HFrEF medication intensification at 5 health systems around the country through a pragmatic cluster-randomized implementation-effectiveness trial. This will occur through an initial phase of adaptation of the 2 tools at each health system. Once ready, the 2 tools will be tested using a 2x2 randomization at the clinician-level. In parallel, formal assessment of the implementation of EPIC-HF and PROMPT-HF will work to understand the most effective means of intervention design and delivery, as well as adaptations due to contextual factors to optimize use.
NCT04573660
The AV-MDR is a prospective, non-randomized, open-label, multi-center registry. The purpose of the AV-MDR study is to proactively collect and evaluate clinical data on the usage of the devices in scope within their intended use with the aim of confirming safety and performance throughout their expected lifetime, ensuring the continued acceptability of identified risks, detecting emerging risks on the basis of factual evidence, ensuring the continued acceptability of the benefit-risk ratio, and identifying possible systematic misuse or off-label usage such that the intended use can be verified as appropriate.
