根据地点、状态和其他条件对此研究列表进行过滤。

1. A Study to Evaluate Aortic Dilatation in Patients with Conotruncal Abnormalities

   Rochester, Minn.

   The purpose of this study is to assess operative and postoperative outcomes after aortic valve surgery, evaluate for changes in ascending aorta diameter by comparing pre-operative CT imaging to measurements on follow-up imaging, and examine late outcomes and functional status during the follow-up period with specific focus on mortality, need for re-operation and incidence of aortic dissection.

2. Left Atrial Appendage Exclusion for Prophylactic Stroke Reduction Trial

   Rochester, Minn.

   The objective of this trial is to evaluate the effectiveness of left atrial appendage exclusion (LAAE) for the prevention of ischemic stroke or systemic arterial embolism in subjects undergoing cardiac surgery who have risk factors for atrial fibrillation and ischemic stroke.

3. A Study of Sexual Dysfunction in Patients with Hypertrophic Obstructive Cardiomyopathy Undergoing Septal Myectomy

   Rochester, Minn.

   The purpose of this study is to determine how many patients suffer from sexual function problems and ascertain if they are improved or modified by cardiac surgical intervention.

4. Hospital Diuretic Therapy and Associated Risk of Heart Failure in Treating Fluid Volume Overload

   Rochester, Minn.

   The objective of this proposal is to assess blood-plasma volume (TBV-PV) status quantitatively in patients with DHF admitted to hospital for volume management, and to determine how effective standard diuretic therapy is in achieving euvolemia and the impact of their quantitated volume status at the time of hospital discharge on heart failure related morality and re-hospitalizations. Thus, to determine if quantitative blood volume analysis could potentially serve as an effective tool to guide more effective in-hospital diuretic therapy to achieve better outcomes in patients hospitalized with clinically identified volume overload.

5. His Bundle Pacing in Bradycardia and Heart Failure

   Rochester, Minn.

   Participants in this study will either have heart failure (HF) and are scheduled to undergo cardiac resynchronization therapy pacemaker (CRT-P) or cardiac resynchronization therapy defibrillator (CRT-D) implantation, or have atrioventricular (AV) block and are scheduled to undergo pacemaker implantation. In this study additional heart rhythm measurements will be collected during the implant procedure to better understand how His bundle and/or parahisian pacing (HISP) effects electrical conduction in the hearts of patients with HF or AV block. The hypothesis is that His bundle or parahisian pacing (HISP) may normalize atrioventricular (AV) conduction with a narrow combination of the Q wave, R wave and S wave (QRS complex) in functional bundle branch block or conduction delay in patients with heart failure (HF).

6. A Study to Establish a Registry for the Pulmonary Hypertension Association

   Jacksonville, Fla.

   The objectives of this study are to measure and improve quality of care (including assessing differences in adherence to evidence-based guidelines and establishing benchmarks for health outcomes); determine the clinical effectiveness, comparative effectiveness, and cost effectiveness of treatment approaches; understand risk factors for outcomes and regional/center differences; and facilitate funded clinical trials of new therapies and collaboration with the PAH community at large, including providers, patients, and their caregivers.

7. 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.

8. A Study to Evaluate DDP3 as a Predictor of Cardiogenic Shock in Patients Presenting with Cardiac Symptoms

   Rochester, Minn.

   The purpose of this study is to evaluate whether DDP3 identifies patients at early risk of cardiogenic shock presenting with STEMI in order to benefit from more aggressive cardiology scrutiny.

    

    

9. A Study to Assess the Current FDA-approved AliveCor Kardia Device to Measure the QT/QTc in Patients Presenting to the Genetic Heart Rhythm Clinic

   Rochester, Minn.

   The purpose of this study is to assess the feasibility of using the current FDA-approved AliveCor Kardia device and their AliveCor Tripod device (FDA Approval pending) to measure the QT/QTc in patients presenting to the Genetic Heart Rhythm Clinic.

10. A Study to Evaluate Sleep for Stroke Management and Recovery

    Rochester, Minn.

    The purpose of this study is to determine whether treatment of obstructive sleep apnea (OSA) with positive airway pressure starting shortly after acute ischemic stroke or high risk TIA (1) reduces recurrent stroke, acute coronary syndrome, and all-cause mortality 6 months after the event, and (2) improves stroke outcomes at 3 months in patients who experienced an ischemic stroke.
