The purpose of this study is to evaluate the safety and effectiveness of the Harmony TPV system.

The purpose of this study is to determine if 3D volumetric measurements will allow more robust quantification of valvular heart disease severity.

The purpose is to study the correlation of right ventricular strain by tissue Doppler and Tricuspid Annular Plane Systolic Excursion (TAPSE) in patients without a tricuspid regurgitation jet with the presence and severity of pulmonary artery hypertension diagnosed by right heart catheterization. The primary aim is to determine the correlation of other echocardiographic, laboratory and clinical findings in patients without a tricuspid regurgitation jet with the presence and severity of pulmonary artery hypertension diagnosed by right heart catheterization. As such, one goal is to potentially create a predictive score with adequate sensitivity to determine which patients without a tricuspid regurgitation ...

The purporse of this study is to determine if biomarker assay obtained at baseline can predict future risk of cardiovascular adverse events, and to  determine if temporal changes in biomarker levels can provide a better risk prediction compared to biomarker assay obtained at baseline.

The purpose of this study is to compare the difference in the ability to detect blood flow abnormalities between invasive assessments performed at rest versus exercise.

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.
