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…
We are studying the natural course of autoimmune hemolytic anemia (AIHA). If you are an adult between 18 and 120 years old, receive care at Columbia University Irving Medical Center-New York Presbyterian Hospital, are willing to provide a blood sample every 6 months for research, and have one of the following diagnoses: AIHA, mixed AIHA, Evans Syndrome, or…
The goal of this early feasibility study is to gain initial insight into the basic safety and performance of transluminal (through the blood vessels) implantation of the PASCAL System's implant (composed of man-made materials). We are trying to evaluate the safety and performance of the PASCAL System with Optimal Medical Therapy (OMT) (also known as…
This is a research study for patients who have Tricuspid Regurgitation (TR), a condition that occurs when the three leaflets of the heart's tricuspid valve do not close properly causing blood to leak backward with each heartbeat. Since some of the blood leaks backward, the heart has to pump more blood with each beat to push the same amount of blood…
The purpose of this study is to develop a cohort of patients with early scleroderma and to collect data on clinical outcomes, radiological tests, laboratory tests, and to obtain biological specimens for testing.
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…
This research is being done to determine how variations in genes may explain the different risk to develop scleroderma (or CREST) seen in African American patients compared to other populations. People who are African American with scleroderma (or CREST) may join. This research involves a blood draw and physical exams.
