The purpose of the HALT Biomarkers study are to identify a panel of circulating proteins that discriminates between patients with and without Hypo-Attenuated Leaflet Thickening (HALT) and can be used to supplement the diagnosis of HALT; to characterize changes in circulating proteins after treatment of HALT with systemic anticoagulation; and to identify circulating proteins that predict the occurrence of HALT. The study population will be adult patients undergoing transfemoral transcatheter aortic valve replacement (TAVR) for severe aortic stenosis (AS) or bioprosthetic valve degeneration. Enrollment will continue until 30 patients with HALT are identified for completion of phase 1. Based on a HALT incidence rate of 10%, we anticipate enrolling 300 patients. Patients are enrolled prior to undergoing transfemoral TAVR. Blood samples, clinical data and echocardiograms will be collected at the following timepoints: baseline (pre-TAVR, T0), post-TAVR (pre-discharge, T1), 30-day follow-up (window 3-9 weeks, T2), and 6-month follow-up (T3). Cardiac 4D CT will be performed at the 30-day follow-up visit to screen for the occurrence of HALT. Patients with HALT will be treated with systemic anticoagulation for 5-6 months, at which point a follow-up CT scan and blood sample will be obtained. Control subjects will also undergo a 6-month study visit with blood sample collection. The study will be conducted within two phases. Phase 1 will serve as a derivation / discovery study in which candidate protein biomarkers of HALT will be identified. Once this is successfully completed, a second cohort will be enrolled within phase 2. Phase 2 will be performed under the auspices a future contract or amendment and will seek to cross-validate the initial study findings. Read Less

Coronary bifurcation lesions are lesions (or blockages) that occur at or near the intersection of a major coronary artery and one of the arteries' side branches. Numerous techniques and devices have been developed to treat coronary bifurcations; however, these types of lesions remain some of the most challenging, both in terms of procedural success and outcome. This study is designed as an observational, multi-center registry that will collect information on treatment strategies and outcomes of consecutive patients undergoing percutaneous coronary interventions (PCI) in coronary bifurcations among various participating centers, in order to determine the frequency of bifurcation PCI, the procedural strategies utilized, and the procedural outcomes.

Coronary angiography and percutaneous coronary intervention (PCI) is often performed in patients with ischemic heart disease. The safety of PCI has improved with new devices and strategies, but complications still occur, especially during complex procedures. The objectives of this multi-center observational registry are to examine frequency of complications occuring during cardiac catheterization and PCI, examine procedural strategies utilized for complication management, and evaluate the clinical outcomes (both immediate and during follow-up.)

The proposed study aims to compare (a) volume contrast administered for Optical Coherence Tomography (OCT) Imaging, (b) length of clear OCT images, and (c) electrocardiographic changes immediately after contrast injection between iso-osmolar and low-osmolar contrast agents. The proposed study is a prospective, single-centered, randomized controlled, study that will compare an iso-osmolar vs. a low-osmolar contrast agent in patients undergoing clinically indicated coronary OCT imaging. Each patient will be randomized to OCT acquisition. Read Less

Cardiac resynchronization therapy (CRT), or atrial-synchronized biventricular (BiV) pacing, is an FDA-approved device therapy option for heart failure (HF) patients with reduced left ventricular ejection fraction and electrical dyssynchrony. A traditional CRT device has pacing leads implanted within the right atrium (RA), the right ventricle (RV), and within a coronary vein overlying the lateral or posterior left ventricle (LV). Within the past decade, various multi-center randomized controlled trials have reported improved quality of life, aerobic exercise capacity, LV systolic function and structure, as well as decreased hospitalization rates and mortality among patients with HF. Despite improvements in CRT technology with multipoint pacing, quadripolar leads, and adaptive pacing algorithms, approximately 30% of patients do not clinically benefit and are considered non-responders. This study looks to optimize CRT device programming in patients considered non-responders to CRTusing information obtained from standard ECG machines, and to assess acute and chronic effects of CRT optimization using cardiac magnetic resonance imaging (CMR).

The purpose of this study is to evaluate if theta burst stimulation (TBS) can reduce chronic headaches caused by a traumatic brain injury (TBI). TBS is a safe, drug-free brain stimulation technique that uses magnets to create electricity and stimulate nerve cells in the brain. After repeated TBS sessions, the increased stimulation of nerve cells can alter the way the brain communicates with itself (by creating new neural pathways) which, in turn, can reduce pain symptoms. Participants in this study will complete a baseline assessment followed by four weeks of daily home headache assessment. Participants will then receive four weeks of TBS administered three times per day and three days per week. After TBS is completed, participants will complete an additional four weeks of daily home headache assessment and return for a one-month follow-up assessment. Participation is expected to last three months. Read Less

This study gathers information on patients at different stages of chronic pancreatitis to better understand the natural course and risk factors associated with pancreatitis. Chronic pancreatitis is a disease that occurs when the pancreas is inflamed (swollen and irritated) all of the time. It is important for doctors to diagnose chronic pancreatitis in the beginning stages of the disease. Over time, as chronic pancreatitis gets worse, the pancreas may stop working correctly. Since treatment options for advanced (end-stage) chronic pancreatitis are limited, patients with early-stage chronic pancreatitis or those at high risk of developing chronic pancreatitis are ideally suited for interventions to prevent the development of end-stage chronic pancreatitis and its associated complications. Information from this study may help researchers to develop lab tests for early diagnosis and prediction of disease progression, to understand disease mechanisms, and to discover genetic factors affecting susceptibility and progression.

A phase III randomized multi-center study designed to compare the efficacy of crenolanib with that of midostaurin when administered following induction chemotherapy, consolidation chemotherapy and bone marrow transplantation in newly diagnosed AML subjects with FLT3 mutation. About 510 subjects will be randomized in a 1:1 ratio to receive either crenolanib in addition to standard first line treatment of AML (chemotherapy and if eligible, transplantation) (arm A) or midostaurin and standard treatment (arm B). Potentially eligible subjects will be registered and tested for the presence of FLT3 mutation. Once the FLT3 mutation status is confirmed and additional eligibility is established, subject will be randomized and enter into the treatment phase. Read Less

The PHA Registry (PHAR) is a national study about people who have pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH). PHAR collects information from people with PAH and CTEPH who are cared for in participating PHA-accredited Pulmonary Hypertension Care Centers throughout the U.S. PHAR will determine how people with PAH and CTEPH are evaluated, tested, and treated, and will observe how well these participants do. The goal is to see if people with PH are treated according to recommended guidelines, and to see if there are certain factors that can lead to better or worse outcomes. PHAR will include information about people with PAH and CTEPH in the U.S. who are seen at participating PHA-accredited PH Care Centers. PHAR contains data about patient care and outcomes. Specifically, data in the PHAR includes information on diagnosis; clinical status; socioeconomic status; diagnosis test results; body size; treatment information; interest in participating in clinical trials; family health and social history; and information about smoking, alcohol, or drug use. Participants are followed over time, and provide updates such as changes in therapy, how often participants need to go to the hospital, and survival. Such information may help healthcare providers provide better care. Read Less
