Investigator: Robert Sommer, MD
Status: Closed
This prospective, multicenter, open-label, single arm, first-in human study will enroll up to 75 subjects aimed at examining the performance of the LAAC device for LAA closure.
Condition: Heart Disease / Arterial Disease
Investigator: Susheel Kodali, MD
Status: Closed
The purpose of this research study, is to learn whether an experimental device (called Evolut R) can help clear hardened blockage in coronary arteries (blood vessels that feed the heart muscle) in patients with a disease is called aortic stenosis.Subjects that choose to participate and are eligible will have their interventional cardiologist use this device…
Condition: Psychiatric Disorders / Obsessive Compulsive Disorder (OCD)
Investigator: Reilly Kayser, MD
Status: Closed
The Center for OCD and Related Disorders at New York State Psychiatric Institute/Columbia University Medical Center is seeking individuals aged 18+ with obsessive-compulsive disorder (OCD) to participate in a survey regarding their experiences with marijuana/cannabis. We hope this study will lead to increased understanding of how these substances affect…
Condition: Valve Disease / Mitral Valve Disease
Investigator: Susheel Kodali, MD
Status: Closed
The purpose of this study is to evaluate a new device to treat patients who may benefit from the repair of their mitral heart valve due to mitral regurgitation. The device is called the Edwards Cardioband System (Edwards Cardioband System or the device). The device is investigational in the United States but has been approved in Europe. This clinical study…
Condition: Heart Disease / Arterial Disease
Investigator: Melvin Weiss, MD, FACC
Status: Closed
The purpose of this study is to see if a new medication called ticagrelor given twice daily ismore effective than aspirin alone in preventing the occurrence of heart attack, stroke and/ordeath due to cardiovascular events in patients who have type 2 diabetes. Ticagrelor is anantiplatelet therapy (stop platelets from clumping together) and is approved for…
Condition: Psychiatric Disorders / Obsessive Compulsive Disorder (OCD)
Investigator: Helen Simpson, MD, PhD
Status: Closed
Eligible participants will be asked questions about their symptoms, complete questionnaires, and receive sessions of Cognitive-Behavioral therapy consisting of Exposure and Ritual Prevention (EX/RP) accompanied by the use of a mobile app. The purpose of this study is to assess whether the mobile app may be effective in improving symptoms of OCD.
Condition: Psychiatric Disorders / Obsessive Compulsive Disorder (OCD)
Investigator: Pablo Goldberg, M.D.
Status: Closed
The purpose of this study is to assess the effects of a single infusion of ketamine for adolescents and young adults with obsessive-compulsive disorder (OCD). Ketamine is a FDA-approved anesthetic medication that can possibly cause a rapid decrease in OCD symptoms. To be eligible to participate, patients need to have already tried at least one SRI…
