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…
This study aims to collect information about the symptoms and treatments of patients who have severely clogged arteries and are treated with commercially available Boston Scientific Corporation drug-eluting devices marketed for the treatment of lesions located in the peripheral vasculature. Participation in the study is expected to last for up to two (2)…
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 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…
This is a prospective, multi-center, observational, post-market study that will evaluate the safety and procedural success of performing trans-radial access for treatment of atherosclerotic lesions in the lower extremities. This research study will collect outcome data of patients undergoing percutaneous endovascular treatment of Peripheral Artery Disease (…
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.
This study is to collect information about the symptoms and treatments of patient who have severely clogged arteries and to learn about their outcomes at one year. If you choose to be part of this research, we will ask you to be involved in five interviews with study staff. Each interview will take about 30 minutes of your time and we will contact you…
This study is to test if a combination drug/device therapy using TEMSIROLIMUS (Temsirolimus Injection), with or without the generic steroid DEXAMETHASONE (Dexamethasone Sodium Phosphate Injection), can be delivered safely into the tissue around the blood vessel wall at the time of an angioplasty ( which is a a procedure to open blocked arteries and restore…
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 purpose of this study is to deterimine if the Drug-Coated Chocolate Touch Balloon Catheters is safe and effective compared to a drug-coated balloon that is already approved in patients with a blockage in the blood vessels of their leg.
This study is for patients who suffer from a condition where one of the blood vessels that deliver blood to your leg has a significant narrowing. This is called peripheral artery disease (PAD). The narrowing may be suitable for a treatment technique called balloon angioplasty. One of the therapies that has been used to treat PAD is balloon angioplasty. It…
