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…
This study is for patients with systemic sclerosis (SSc) and associated Interstitial Lung Disease. Systemic sclerosis or systemic scleroderma is a disease that causes thickening of the skin and the internal organs which often includes the kidneys, heart, lungs and…
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…
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-…
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…
The objective of the Block-COPD Study is to determine if beta-blockers are safe and effective at reducing the number of exacerbations or flare-ups that people living with Chronic Obstructive Pulmonary Disease (COPD) experience. A beta-blockers is a drug that is taken by mouth and is currently used to treat a wide range of…
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…
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 is a clinical research study designed to determine the safety and effectiveness of the TIVUS system, an investigational device used in the treatment of PAH. The TIVUS System is intended to treat patients with pulmonary artery hypertension by injuring the sympathetic nerves surrounding the pulmonary vasculature (denervation) using ultrasonic energy. The…
This study involves two infusions of either rituximab or placebo, two right heart catheterizations (6 months apart), and a variety of other clinical study procedures and exams.
