Clinical Trials

The purpose of the study is to test whether cardio-ankle vascular index, a measure of arterial stiffness that can be obtained in the office setting, is associated with cardiac function and structure as assessed by echocardiography.

The purpose of this study is to evaluate Patent Foramen Ovale (PFO) closure for migraine headache relief using the GORE® CARDIOFORM Septal Occluder after a trial of oral anticoagulation therapy vs. placebo for a 6 week period.

The purpose of this study is to evaluate the transthoracic echocardiographic (TTE) findings associated with rapid weight loss and season training among competitive collegiate wrestlers. In addition,to evaluate body composition, weight loss methods and energy availability at different time points during the season.

We hypothesize that the degree of rapid weight loss will be associated with abnormalities of myocardial function.

The aim of this study is to prospectively validate the novel AI based model in patients undergoing clinically indicated transthoracic echocardiography using a four-chamber view acquired with a hand-held point of care ultrasound.

The purpose of this study is to assess the correlation between myocardial elasticity (ME) measurements obtained simultaneously during cardiac hemodynamic catheterization and intraprocedural echocardiography.

The purpose of this study is to evaluate the use of a non-invasive bedside echocardiography to assess the effect of mechanical ventilation (invasive and non-invasive) on the function of the heart.

The purpose of this study is to improve the noninvasive assessment of right atrial pressures by correlating tradiational echo findings with other echo indicators using the gold standard of right heart catheterization as the correlation.

The aim of this study is to identify genes shared between humans and rhesus macaque primates who have been diagnosed with hypertrophic cardiomyopathy and have died suddenly.

The purpose of this study is to prospectively evaluate a newly-developed screening tool for ALVSD.

The purpose of this study is to perform and analyze standard transthoracic echocardiography with contrast and strain imaging in 80 consecutive patients seen in the Mayo Clinic Spontaneous Coronary Artery Dissection (SCAD) Clinic and interpret any prior pre- or post-SCAD echocardiogram studies for comparison.

The purpose of this study is to compare the hemodynamic effects of Low Flow versus Normal Flow Aortic Stenosis after Transcatheter Aortic Valve Replacement.

We hypothesize that (1) Patients with significant left atrial pressure (LAP) reduction during transcatheter mitral valve repair (TMVR) have lower cardiac output, more advanced diastolic dysfunction, increased left atrial stiffness, abnormal pulmonary vascular function and higher arterial afterload compared to TMVR patients without a significant LAP reduction. (2) TMVR and associated reduction in mitral regurgitation and LAP results in relief of pulmonary vascular congestion, and improvement in pulmonary vascular and right ventricular function.
