Patients with large abdominal aortic aneurysms (AAA) (>5.5cm) are recommended to have surgery, but there is no therapy for small AAA (3-5cm). The purpose of this study is to collect ultrasound images and blood from patients with normal abdominal aorta as well as from patients with small AAA. Study participants include patients scheduled for an aortc ultrasound aorta and may fall into one of these categories. By analyzing the aortic wall ultrasound images and the blood levels of particular proteins, we hope to identify a target for drug therapy to stop AAA growth. Voluntary participation in this study does not change the original intent of the ultrasound and does not change patient treatment. The pictures gathered here are in addition to the standard ultrasound and cause no additional risk. Participation would include the standard aorta ultrasound, specific extra pictures (less than 5 minutes to collect), and collection of a blood sample. If a participant's aorta is within normal limits, no additional ultrasound visits or study visits will be indicated. If the participant has a small AAA, standard of care would be to return once per year for repeat ultrasound. Ongoing participation in the study will be to have the extra ultrasound images captured and repeat blood sampling, for a total of 3 years.

The purpose of this registry is to collect safety data in patients undergoing aortic aneurysm repair, peripheral vascular intervention, hemodialysis access intervention or peripheral embolization with an eligible Medtronic market-released product(s), including but not limited to balloon catheters, peripheral or carotid stents, stet grafts, and coils, in a real-world setting.

This is a study comparing the new class anticoagulants factor XIa to the FDA approved Apixaban. The study is to determine if Milvexian is as effective and safe with preventing clots for patients with A-fib and to determine if Milvexian is better at reducing the chances of bleeding.

This study will compare WATCHMAN FLXTM ("DEVICE") to a category of OAC called non-vitamin K antagonist oral anticoagulation, also known as NOACs ("CONTROL"). NOAC medications include Pradaxa® (dabigatran), Eliquis® (apixaban), Xarelto® (rivaroxaban), or Savaysa® (edoxaban).The study will research the safety and effectiveness of the WATCHMAN FLXTM device compared to treatment with NOAC therapy to determine if it works for patients with your type of atrial fibrillation who require treatment for potential blood clot formation (thrombus) in the LAA.

The purpose of this research study is to develop a better understanding of the cause and natural history of vascular anomalies and related syndromes. This study is being done in order to develop a better understanding of the cause of vascular anomalies in order to to improve care for people who are affected by these anomalies and related syndromes.

This study is being done at the University of Wisconsin-Madison (UW-Madison) and other sites in North America and Europe. A total of about 1000 people will participate in this study. About 20 – 30 people will take part in the study here at the Medical University of South Carolina.

In current practice, options for venous and lymphatic malformations remain limited. Recently an oral medication, sirolimus, has been found to benefit patients when taken once or twice a day for several months. Unfortunately there are many side effects associated with this medication, some of which can be severe including, neutropenia, oral ulcerations, and lab abnormalities. The purpose of this study is to determine if once weekly dosed sirolimus will be effective for the treatment of venous and lymphatic malformations. Additionally, the study will evaluate patient satisfaction and identify adverse effects. Participants will be on the medication for 6 months with an option to continue after this time period.

The purpose of the study is to generate a bio bank of specimens for research. We will tissue that would otherwise be discarded from clinical or surgical procedure and information from medical records. We will also collect discarded blood, urines and sputum. Collecting samples will help to better understanding the mechanisms of cardiovascular diseases, identify biomarkers for early diagnosis and to predict safety and efficacy of new therapies.
