This is a prospective multicenter study whose purpose is to establish the safety and effectiveness of the Edwards SAPIEN 3 and SAPIEN 3 Ultra valves with Commander delivery system in patients with severe symptomatic calcific mitral valve disease with severe mitral annular calcification (which is a progressive loss of function of the mitral valve due to…
The Columbia Otolaryngology Department is interested in understanding the intersection of vaping, smell, and taste and their impact on individuals' preferences for certain flavors. Participation will involve answering a series of questionnaires in addition to completing a formal evaluation of your smell and taste with standardized measurements. You can…
This is a randomized controlled trial (RCT) that will compare the clinical outcome of MitraClip device versus surgical repair in patients with severe primary MR who are at moderate surgical risk and whose mitral valve has been determined to be suitable for correction by MV repair surgery by the cardiac surgeon on the local site heart team. In this trial,…
The study is designed to compare the safety and effectiveness of the PASCAL System to the MitraClip System for reduction of degenerative mitral regurgitation.
The use of electronic cigarettes, also known as e-cigs or vaping, has increased among former smokers and young adults who have never smoked. Relatively little is known, however, about their health effects (whether they are adverse, have no effect, or are beneficial). The purpose of this research study is to evaluate (1) the association of e-cig use with…
We are inviting patients with active Rheumatoid Arthritis (RA) to help us better understand how treatment options affect inflammation in soft tissues. With a combination of blood work, a full-body FDG PET-CT scan, questionnaires, and a soft tissue biopsy (from an area around the belly button), we hope to see how RA interacts with these multiple areas of…
This is a four-session study in which we will be recruiting existing cigarette smokers to explore the competitive dynamics between memory encoding and memory retrieval. To participate, you will first go through a phone screening to determine eligibility and learn about the study. Then you will be asked to visit our facility at the Morningside Campus of…
This study is designed to look at the safety and performance of The Intrepid TMVR System using transfemoral transseptal access (TF). TF is a procedure that requires access to the femoral vein by an incision in the lower limb between the knee and the hip. The study population is for patients with severe, symptomatic mitral regurgitation (MR), a condition…
The Millipede Feasibility Study is a prospective, open-label, single-arm study to assess the safety and feasibility of the Millipede Transcatheter Annuloplasty Ring System in subjects with functional mitral regurgitation. The Millipede Annuloplasty Ring System is a novel transcatheter, fully adjustable, complete annuloplasty repair device for the treatment…
The study aims to compare the effect two different RA treatments on cardiovascular health in patients who are considering a treatment change. The study is recruiting patients who are only taking methotrexate and are switching treatment due to a lack of improvement. The trial will randomize participants to take a TNF inhibitor (Enbrel or Humira) in addition…
The purpose of this study is to evaluate a new device to treat patients who may benefit from the repair of their mitral heart valve due to mitral regurgitation. The device is called the Edwards Cardioband System (Edwards Cardioband System or the device). The device is investigational in the United States but has been approved in Europe. This clinical study…
We are doing a research study to learn more about why people with rheumatoid arthritis (RA) are prone to heart disease. We are recruiting patients diagnosed with Rheumatoid Arthritis without a personal history of heart disease. This study involves one initial full visit as described below, and a brief follow up visit that will take place approximately 2 or…
This trial is a non-randomized, prospective, multi-center early feasibility study to evaluate the safety and performance of the AccuCinch system in patients with Heart Failure and Reduced Ejection Fraction HFrEF
