1. A Study To Collect Thoracic Specimens To Develop A Thoracic Specimen Registry

   Scottsdale/Phoenix, Ariz., Jacksonville, Fla., Rochester, Minn.

   The primary objective of this proposal is to develop a Thoracic Specimen Registry at Mayo Clinic. The purpose of the registry will be to support ongoing research in the etiology, early diagnosis, clinical management, and prognosis of lung cancer and other cancers and diseases of the thorax by developing a complete repository of specimens from patients with thoracic disease including but not limited to suspected lung cancer, mediastinal and pleural tumors and from patients at a very high risk of developing other thoracic cancers or other thoracic diseases. 

2. CTSN Embolic Protection Trial

   Rochester, Minn.

   The purpose of this study is to analyze the effectiveness and safety of an embolic protection device compared to a standard aortic cannula to reduce the effects of death, clinical stroke, delirium and acute kidney injury in high-risk valve surgery patients.

3. Study to Determine the Accuracy of a New Venous Air Plethysmograph in People with Normal, Incompetent, and Obstructed Venous Hemodynamics.

   Rochester, Minn.

   The purpose of this study is to determine the accuracy (sensitivity, specificity, negative predictive value, positive predictive value) of a new venous air plethysmograph in people with normal, incompetent, and obstructed venous hemodynamics.

4. Estimation of Biomechanical Aortic Wall Properties in Healthy and Aneurysmal Aortas Using Novel Imaging Techniques

   Jacksonville, Fla.

   The primary aim of this study is to establish the practicality of using two novel imaging modalities for the assessment of biomechanical properties of the aorta.

5. Detection of Vascular and Inflammatory Plasma Biomarkers in Patients Diagnosed with Obstructive Sleep Apnea and MRI-defined Cerebral Small Vessel Disease

   Jacksonville, Fla.

   The purpose of this study is to evaluate plasma biomarkers of vascular function and inflammation in patients with newly-diagnosed Obstructive Sleep Apnea (OSA) and pre-existing imaging evidence of Cerebral Small Vessel Disease (CSVD).

6. RLY-2608-201-Ph2 Study Of RLY-2608 In PROS And PIK3CA Driven Malformations

   Rochester, Minn.

   The purpose of this study is to compare the efficacy and safety of RLY-2608 versus placebo in adult, adolescent, and pediatric participants with PROS and malformations driven by PIK3CA mutations, which is preceded by a dose selection and basket design with exploratory single-arm cohorts for various subpopulations of participants.

7. Spontaneous Coronary Artery Dissection: Case Review

   Rochester, Minn.

   Spontaneous coronary artery dissection (SCAD) is uncommon but important cause of acute coronary syndrome and sudden cardiac death. There is very little data exists in regards to patient clinical characteristics, risk factors, treatment and outcomes. Our objective is to prospectively assess long term outcomes. 

8. CT Angiography of the Aorta following Fenestrated Branched Endovascular Aneurysm Repair (F-BEVAR) using Tube Potential Selection and Weight-based Method: Effects on Image Quality and Radiation Dose

   Rochester, Minn.

   The objective of this study is to evaluate the image quality and radiation dose of a CT angiography protocol (CTA) using tube potential selection and weight-based method.

9. Treatment In Thoracic Aortic Aneurysm: Surgery Vs Surveillance

   Rochester, Minn.

   The ascending aorta conducts blood from the heart to the rest of the body. The ascending aorta can become enlarged, and the risk of tearing and rupturing becomes higher with larger aorta. When the ascending aorta tears or ruptures, the risk dying is high even if surgery is done as soon as possible. Traditionally, when the ascending aorta gets above 5.5 cm, surgery is recommended to replace the aorta. However, this threshold is based relatively weak evidence, and sometimes patients with smaller aorta can tear or rupture. On the other hand, surgery carries its own risk as well. Since there are risk of waiting or doing surgery, there is currently no great support for either approach for patients with a smaller aorta. In the TITAN SvS trial, patients with an ascending aorta between 5.0 to 5.5 cm is assigned by chance to the early surgery group, in which they will undergo replacement of aorta, or the surveillance group, in which they will be closely monitored. The chance of dying or suffer tearing or rupture of aorta between the two groups will be compared. The result of the trial will guide future practice for patients with enlarged ascending aorta.
   
   This is a prospective, multi-centre randomized control trial that compares the all-cause mortality, aneurysm-related aortic events, rate of stroke, and quality of life for those patients undergoing early elective ascending aortic surgery to those patients undergoing surveillance. Patients referred for an ascending aortic aneurysm that meets the inclusion criteria will be randomized to the early elective surgery group or the surveillance group. Recruitment will end when the desired sample size is reached, and the patients will be followed for a minimum 2-year period. The primary objective of the trial is to compare the composite outcome of the all-cause mortality and incidence of acute aortic events between surveillance and elective ascending aortic surgery for patients with degenerative or bicuspid valve-related ascending aortic aneurysm after 2 years of follow up. The hypothesis is that the early surgery group will have a significantly lower all-cause mortality and incidence of acute aortic events at 2 years of follow up compare to the surveillance group. The result of this trial will provide evidence based guidance in the appropriate management of ascending aortic aneurysm based on the size criteria, and establish a large database for future investigations.

10. A Study To Evaluate Endovascular Ablation Of The Right Greater Splanchnic Nerve In Subjects Having Heart Failure With Preserved Ejection Fraction

    Rochester, Minn.

    The objective of this clinical evaluation is to assess the safety and initial effectiveness of catheter-based unilateral ablation of the right greater splanchnic nerve (GSN) in subjects having heart failure with preserved ejection fraction (HFpEF).
