The AFFECTS Study: Assessment of Fractional Flow reservE Computed Tomography versus Single photon emission computed tomography in the diagnosis of hemodynamically significant coronary artery disease

The overall objective of the AFFECTS Study is to assess the disagreement between SPECT and FFRct in identifying vessel-specific, hemodynamically significant CAD in patients scheduled for invasive coronary angiography (ICA) based on abnormal SPECT myocardial perfusion scans.

Role: Data Coordinator

Assessment of long term AF in patients with post-MVR new-onset AF

To assess the incidence of Atrial Fibrillation (AF) after discharge in patients with new onset Atrial Fibrillation after Mitral Valve Repair (MVRp) or Mitral Valve Replacement (MVR).

Role: Data Coordinator

Comparison of outcome between the robotic and port access Mitral valve repair

To compare the outcome and treatment costs of all patients who underwent isolated MVR either using a minithoracotomy or robotic approach at THHBP.

Role: Data Coordinator

The Optimization of Surgical Therapy for Infective Endocarditis – Long Term Outcomes

To assess the short-term outcome of all patients who underwent aortic valve surgery due to IE and compare the outcome to patients who underwent isolated aortic valve surgery due to other reasons.

Role: Data Coordinator

Effectiveness of ranolazine at admission and/or discharge in reducing re-admissions after PCI

This population-based, multi-site observational study will provide important information about ranolazine’s potential to prevent short- and long-term re-hospitalizations after cardiac catheterization/PCI, and the associated impact on costs of care. This information will be useful in updating clinical guidelines/best practices for patients undergoing cardiac catheterization/PCI, and to decision-makers setting policies regarding the indications for and re-imbursement coverage of ranolazine as a prophylactic and/or therapeutic agent.

Role: Data Coordinator

Pacemaker Utilization and Ventricular Pacing in Patients undergoing Transcatheter Aortic Valve Replacement (TAVR)

To assess the incidence (at 90-days) of ventricular pacing in patients undergoing permanent pacemaker placement after TAVR.

Role: Data Coordinator

Left Atrial Appendage Closure with SentreHeart Lariat® Device

The primary aim is to assess the outcome of patients undergoing left atrial appendage ligation or closure with the SentreHeart Lariat® device as a stand-alone procedure at the participating centers.

Role: Data Coordinator

Assessment of the Role of Balloon Aortic Valvuloplasty in the Management of Patients with Aortic Stenosis

The aim of the study is to determine the safety, effectiveness, and outcomes of BAV procedures in the current clinical setting as a “bridge” to valve replacement or as definitive treatment.

Role: Data Coordinator

Hybrid Revascularization for Patients with Multivessel Coronary Artery Disease

This study aim is to assess outcome differences with composite of acute kidney injury, major or minor bleeding, admission for pleural effusion post surgery and reoperation during index hospitalization between patients whose CAD was treated with a hybrid revascularization and patients whose CAD was treated with conventional multivessel CABG. The study will also assess differences between hybrid revascularization strategies (concomitant revascularization versus staged approach –with PCI coming before or after surgery) and renal failure and bleeding, evaluate and characterize each coronary lesion to determine if these lesions were optimal for the hybrid approach, or if they affected the need for repeat revascularization, and utilize the results of the study to create a registry moving forward to serve as the basis for a prospective evaluation of hybrid revascularization.

Role: Data Coordinator

A Novel Low-dose-contrast Cardiac Computed Tomography Method for Pre-Procedural Guidance in Transcatheter Aortic Valve Replacement

The study is a retrospective cross-sectional study assessing image quality and safety from a renal standpoint between low-dose-contrast CCTA and traditional-dose-contrast, and effectiveness of low-dose-contrast CCTA in analyzing the complex dynamic 3-pronged aortic annulus geometry pre-procedurally in TAVR to improve procedural and patient outcomes.

Role: Data Coordinator

A Novel Imaging Approach to Assess Paravalvular Leak for Transcatheter Valve Replacement

The study objective is to assess the agreement between cMRI PVL grading (based on regurgitant fraction) and TTE PVL grading (based on pressure half-time and the ratio of the jet arc to the circumference of the annulus).

Role: Data Coordinator

Improving the Quality of Echocardiographic Imaging Measurements in the Diagnosis of Severe Aortic Stenosis

The primary objective of this study is to review the current practice of transthoracic echocardiogram (TTE) imaging measurements in conjunction with computerized tomography (CT) and to standardize these measurements in order to improve the accuracy of the diagnosis of aortic stenosis (AS).

Role: Data Coordinator

New-onset post-CABG atrial fibrillation and survival in women

This is a retrospective population-based multicenter study assessing the effectiveness of optimal preventive and management strategies and their impact on incidence of new-onset post- CABG atrial fibrillation and long-term survival in women.

Role: Data Coordinator

New-onset post-CABG atrial fibrillation

This is a large multicenter observational study which includes 32,420 consecutive patients without pre-operative AF who underwent isolated CABG between 1/1/1997 and 12/31/2008 at Baylor University Medical Center (Dallas, TX), Emory University (Atlanta, GA), University of Virginia (Charlottesville, VA), and Washington University (St. Louis, MO) using data from the STS database, patient medical records, administrative data, and the Social Security Administration Death Master File. The study seeks to evaluate the effectiveness of the prophylaxis and management strategies for new-onset AF following isolated CABG and their impact on long-term survival (>15 years).

Role: Data Coordinator

A randomized trial assessing the association between type of local anesthesia treatment and postoperative pain in patients having undergone arrhythmia surgery

The goal of the study is to investigate the relationship between two standard treatments, lidocaine or a mixture of lidocaine and marcaine, and 1) postoperative pain; 2) narcotic use following pacemaker or defibrillator insertion in consecutive subjects who undergo arrhythmia surgery at Baylor Heart and Vascular Institute.

Role: Project Coordinator

Non-contrast 3-dimensional cardiac magnetic resonance imaging as pre-procedural guidance for Trans-catheter Aortic Valve Replacement in assessing the aortic valve apparatus

Role: Data Coordinator

A large population-based study of surgery for abdominal aortic aneurysms

Role: Data Coordinator

A randomized trial assessing the association between type of local anesthesia treatment and postoperative pain in patients having undergone arrhythmia surgery
