There are 2 arms in this study: Transseptal Valve-in-MAC (ViMAC) and a control arm of patients treated with medical treatment only which will include patients who can't be treated due to the presence of anatomical exclusion criteria or other exclusion criteria.

The purpose of this study is to establish the safety and effectiveness of the SAPIEN M3 System in subjects with mitral regurgitation (MR) who are at high surgical risk.

The goal of this study is to create a comprehensive system of blood and tissue banking of samples from Mayo Clinic Arizona patients with a clinical diagnosis of aortic stenosis who are either undergoing routine care at Mayo Clinic or undergoing aortic valve surgery.  The tissue samples will be used for future research of aortic stenosis at Mayo Clinic and future research at Mayo Clinic to learn about, prevent, or treat other health problems.

The purpose of this study is to evaluate the safety and effectiveness of the HARPOON System in the treatment of patients with severe degenerative mitral regurgitation.

The purpose of this study is to evaluate the outcomes of surgical Aortic Valvotomy for congenital aortic stenosis.

The purpose of this study is to find if cardiopulmonary exercise testing data will provide any predictive information in evaluating patients with aortic stenosis for severity, symptoms and surgical risk.

Study to evaluate the safety and performance of the INNOVALVE system

The primary objective of this trial is to test the safety and efficacy of Perceval versus standard sutured stented bioprosthetic aortic valves among the intended trial population.

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.

The aims of this investigation are:

To assess the predictive value (and accuracy) of clinical and physiologic preoperative variables in identifying patients at risk for the development of new-onset atrial arrhythmia after cardiac surgery.

To assess the feasibility of a physiological risk model based on clinical and echocardiographic indexes to predict post-operative AF.

To assess the role of prophylactic agents in the prevention of new-onset postoperative POAF

To assess the economic impact of new-onset postoperative AF:

• Length of hospital stay (will be measured as fractions of days)

• Hospital cost (will be measured in standardized dollars)

• Resource utilization (will be measured by resource-based relative-value units)

To assess the outcome ...

The purpose of this study is to see if , with the help of a new software program to find the aortic valve angles, accurate placement of a new valve can be improved during a total aortic valve replacement procedure.

The purpose of this work is to evaluate the feasibility of a new Cardiac Vascular Reconstruction (CAVAREC, Siemens Medical Systems, Germany) image reconstruction algorithm for use during transcatheter aortic valve implant (TAVI) procedures. CAVAREC utilizes the same x-ray projection images as currently acquired for clinical DynaCT. X-ray image acquisition to allow CAVAREC will occur during the TAVI procedure both before and after the TAVI device is implanted. The CAVAREC image processing algorithm will be implemented on an off-line workstation after the TAVI procedure is complete. After the TAVI procedure, CAVAREC images will be quantitatively and qualitatively compared to Siemens DynaCT ...

The purpose of this study is to provide a survey to prospective candidates undergoing transcatheter valve replacement or repair at two time-points to assess grit, a psychological composite of personal diligence which has been validated to predict retention in other pursuits of long-term goals over and above assessments limited to intelligence and physical aptitude.

The purpose of this study is to evaluate the safety and performance of the HLT System in patients with severe aortic stenosis who present at High Risk for aortic valve replacement surgery.

The purpose of this study is to establish the safety and effectiveness of the Edwards SAPIEN X4 Transcatheter Heart Valve (THV) in subjects with symptomatic, severe, calcific aortic stenosis (AS).

The purpose of this trial is to generate clinical evidence on valve safety and performance of self-expanding (SE) versus balloon-expandable (BE) transcatheter aortic valve replacement (TAVR) in subjects with a small aortic annulus and symptomatic severe native aortic stenosis.

The purpose of this study is to obtain safety and effectiveness data to support indication expansion for the Medtronic transcatheter aortic valve replacement (TAVR) System to include patients with moderate, symptomatic Aortic Stenosis (AS).

The purpose of the study is to determine the feasibility of administration of high dose intravenous ascorbic acid in the operative and post-operative environments as well as sample size for a prospective, randomized, placebo controlled study.

The purpose of the research is to determine whether repairing a tricuspid valve (TV) in patients with mild to moderate tricuspid regurgitation (TR), at the time of planned mitral valve surgery (MVS), would improve the heart health of those who receive it compared to those who do not. At this point, the medical community is split in their opinion on whether surgeons should routinely repair mild to moderate TR in patients who are undergoing planned mitral valve surgery, and this study will answer this question.

Classical echocardiographic assessment of heart valves is critical in determination of disease severity. However, echocardiography has only limited ability to predict how well an individual patient will do at time of surgery. New echocardiographic technology allows us to measure new, more refined parameters of your heart’s performance. This study is investigating whether these new parameters are better in predicting outcomes.

The purpose of this study is to look at liver stiffness with a MRI sequence called Magnetic Resonance Elastography (MRE). The study will let the investigators know whether the subject's liver is normal or has increased stiffness. Increased liver stiffness often means there is chronic liver disease and fibrosis. Increased right heart pressure and congestive heart failure are considered risk factors for development of liver fibrosis. Liver fibrosis, if progressive, may lead to cirrhosis and its related complications. The increased liver stiffness may be due to a poorly functioning tricuspid valve. With this research, the investigators will be able to ...
