Examining symptoms and severity of mitral regurgitation

Assessing the Impact of Diastolic Dysfunction on the Presence of Symptoms in Patients with Primary Mitral Regurgitation.

Observational Atlantic Health System · NCT06738615

What this trial studies

This observational study focuses on patients with mitral regurgitation who are undergoing left heart catheterization prior to mitral valve surgery or intervention. Participants will undergo a series of evaluations including cardiovascular magnetic resonance imaging (CMR), cardiopulmonary exercise testing (CPET), and the Kansas City Cardiomyopathy Questionnaire (KCCQ) to assess their symptoms, exercise capacity, and the severity of their condition. The study aims to explore the relationship between diastolic dysfunction and symptoms in patients with mitral regurgitation, providing insights into how these factors interact. By measuring intracardiac pressures and volumes during catheterization, researchers hope to better understand the underlying mechanisms of symptoms in this patient population.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older with primary degenerative mitral regurgitation and a left ventricular ejection fraction of 50% or greater who are scheduled for cardiac catheterization.

Not a fit: Patients with secondary mitral regurgitation, those with a left ventricular ejection fraction below 50%, or those with significant coronary artery disease may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved management strategies for patients with mitral regurgitation by clarifying the relationship between symptoms and disease severity.

How similar studies have performed: While the approach of using CMR and CPET in this context is established, the specific focus on diastolic dysfunction in relation to symptoms of mitral regurgitation is relatively novel.
