The objective of the study is to evaluate the safety and efficacy of the JenaValve Pericardial TAVR system when treating patients with aortic regurgitation. Aortic Regurgitation is a condition that develops when the heart's aortic valve does close tightly, therefore the blood leaks back into the heart chamber. The JenaValve Pericardial TAVR system will…
My Hand Project for Stroke Patients: We are testing a robotic device to help people who had a stroke use their weak hand more easily. This research study would involve you wearing a hand robot that helps open and close your fingers in order to use your hand to pick up common everyday objects. During the study, you may be asked to try out different…
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…
The high incidence and variety of conduction disturbances post-TAVR represents a major challenge in the periprocedural management of TAVR recipients. Despite the growing body of knowledge on this topic, the large variability in the management of these complications has translated into a high degree of uncertainty regarding the most appropriate treatment of…
This prospective, multicenter trial is looking at the investigative device called the ACURATE Transcatheter Aortic Valve System for TAVR to see if it is safe and effective in treating patients with severe symptomatic native aortic stenosis. The ACURATE Transcatheter Aortic Valve System for TAVR is designed for iliofemoral access and delivery of a self-…
Aortic stenosis (AS) or narrowing of the arteries remains one of the most common valvular diseases in the Western population requiring intervention. The deterioration of the aortic valve is more common in the older population and usually along with coronary artery disease (CAD) requires the need for treatment. This is a study that is collecting safety and…
This program aims to help improve adult caregivers of stroke survivors ability to care for their stroke survivors with their daily needs. Each session will cover different topics which are important for caregivers to understand in order to best engage in their new role. Topics will include, but are not limited to: bathing, toileting, dressing, transfers,…
The purpose of this research is to learn about types of practice that may benefit stroke survivors when learning to use their weaker arm to perform a task. Potential participants will be asked to come to Columbia University Irving Medical Center (CUIMC) for a screening session. Eligible participants will be randomized into two groups with different practice…
This is a prospective, multicenter, non-randomized, single-arm, open-label clinical study, sponsored by Pi-Cardia. Fifteen (15) patients with symptomatic severe Aortic Stenosis (narrowing of the aortic valve) who are considered operable but are not recommended by the heart team for immediate treatment with surgical or transcatheter aortic valve replacement…
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…
The study is to determine whether aortic valve replacement is helpful for patients who have moderate-severe, calcific, aortic stenosis (a narrowing of the aortic heart valve, where calcium has attached to the valve surface, resulting in obstructed blood flow) and do not have symptoms. Subjects will be randomly assigned, l to one of two groups: (1) Treatment…
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…
The study is to determine whether aortic valve replacement is helpful for patients who have severe, calcific, aortic stenosis (a narrowing of the aortic heart valve, where calcium has attached to the valve surface, resulting in obstructed blood flow) and do not have symptoms.
The objective of this study is to collect outcome data on valve performance and a pre-specified TAVR care pathway. Transcatheter aortic valve replacement (TAVR) has been shown to be a safe and effective treatment for patients with severe aortic stenosis who are at extreme, high, or intermediate surgical risk. Since CoreValveTM became commercially approved…
The Amulet IDE trial is a prospective, randomized, multi-center active control worldwide trial, designed to evaluate the safety and effectiveness of the AMPLATZER Amulet Left Atrial Appendage Occluder. Subjects will be randomized in a 1:1 ratio between the Amulet LAA occlusion device (treatment) or a Boston Scientific WATCHMAN LAA closure device (Control).…
We are looking for adults who have had a stroke to participate in testing of a new robotic device for the hand. If you had a stroke over six months ago and now have difficulty using your hand, you may qualify to participate in this study. Time commitment: ~4 weeks, 3x/week, Compensation: $50 per testing visit, $25 per training session.
Stroke often results in limitation of arm movements, from which many people do not fully recover. We believe that early and intensive therapy is important to enhance recovery of arm movements after stroke. We are doing this research study to see how much arm movements improve with intensive therapy in patients have had a stroke in the past 5 weeks. We will…
