Condition: Valve Disease / Aortic Valve Disease
Investigator: Torsten Vahl, MD
Status: Currently Recruiting
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…

Investigator: Elizabeth Verna, MD
Status: Closed
This research trial is being conducted to determine the safety and efficacy of HARVONI (an FDA-approved Hepatitis C Virus medication) in HCV (genotype 1, 4, 5, an 6) infected patients who also have advanced heart failure or chronic lung disease. HARVONI has not been tested in patients with HCV and heart failure or chronic lunch disease. Subjects will take…
Condition: Liver Disease / Hepatitis
Investigator: Steven Lobritto, MD
Status: Closed
The purpose of this study is to learn more about the effects of the combination of telaprevir peginterferon alfa2b (Peg-IFN) and ribavirin (RBV) in children with chronic hepatitis C. Investigators will look at how these study drugs may affect childrens bodies and how children break down and eliminate telaprevir. Participants of this study will receive Peg-…
Condition: Heart Disease / Arterial Disease
Investigator: Manish Parikh, MD
Status: Closed
The purpose of this research is to find out whether it is safe to shorten the length of time that people at high risk for bleeding take blood thinners after being treated with a coronary stent.
Condition: Liver Disease / Hepatitis
Investigator: Elizabeth Verna, MD
Status: Closed
The purpose of this study is to determine how safe and effective using three medications (pegylated-interferon, ribavirin and boceprevir) are in curing HCV in patients with end stage kidney disease on hemodialysis. Participants will be prescribed these three medications and will be followed closely through treatment, then for 6 months afterwards. During…
Condition: Heart Disease / Arterial Disease
Investigator: Michael Collins, MD
Status: Closed
This study is for patients with Coronary Artery Disease (CAD) and require a stent placement. The purpose of this clinical research study is to assess the safety and effectiveness of the Orsiro stent or a non-investigational Xience stent. The Orsiro stent is investigational, which means it is not yet approved by the FDA and can only be used in research…
