Cardiac MRI for Tricuspid Regurgitation
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial uses cardiac MRI (a detailed heart scan) to assess the severity of tricuspid regurgitation, a condition where the heart's tricuspid valve doesn't close tightly, potentially causing problems. Patients with moderate or severe tricuspid regurgitation will undergo an MRI to evaluate their condition. Those with more than moderate tricuspid regurgitation and no metal devices like pacemakers are suitable candidates. This process helps doctors better understand the condition and plan future care. As an unphased trial, it offers patients the chance to contribute to medical knowledge and improve future treatments for tricuspid regurgitation.
Do I have to stop taking my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications.
What prior data suggests that cardiac MRI is safe for assessing tricuspid regurgitation?
Research has shown that cardiac magnetic resonance (CMR) safely and effectively examines heart conditions, including tricuspid valve issues. CMR is non-invasive, meaning it doesn't require surgery or inserting instruments into the body. Studies have found that CMR is generally safe and well-received by patients in medical settings.
In one study, CMR succeeded in all procedures, with no procedure-related deaths and 98% of patients experiencing no major side effects within 30 days. Another study demonstrated that CMR does not harm the left side of the heart, reassuring patients concerned about other heart functions.
Overall, CMR appears to be a reliable and safe imaging option for individuals with heart valve issues.12345Why are researchers excited about this trial?
Researchers are excited about using Cardiac Magnetic Resonance (CMR) for tricuspid regurgitation because it offers a non-invasive and highly detailed way to assess the severity of the condition. Unlike traditional echocardiography, CMR provides clearer images of the heart and surrounding structures, which can reveal extra-valvular cardiac and liver abnormalities. This method could lead to more accurate diagnoses and better-tailored treatments for patients, potentially improving outcomes.
What evidence suggests that cardiac MRI is effective for assessing tricuspid regurgitation?
Research has shown that cardiac magnetic resonance (CMR) is a valuable tool for evaluating tricuspid regurgitation (TR), a condition where the heart's tricuspid valve doesn't close properly. In this trial, patients with moderate or severe TR will undergo CMR to assess TR severity and associated cardiac and liver abnormalities. CMR provides more accurate assessments of TR severity than traditional ultrasound tests. Studies have found that certain CMR measurements correlate with outcomes like a higher risk of death in severe TR cases. This imaging method offers a clearer view of heart function and can help predict the condition's progression. Therefore, CMR is a promising way to assess patients with TR.16789

Are You a Good Fit for This Trial?
This trial is for individuals with moderate or severe tricuspid regurgitation, which is when the heart's tricuspid valve doesn't close properly. Participants must not have a pacemaker/defibrillator that interferes with MRI, any prior tricuspid valve replacements, planned surgery on the tricuspid valve, or primary liver disease.Inclusion Criteria

Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Imaging Assessment
Participants undergo cardiac magnetic resonance imaging (CMR) and magnetic resonance elastography (MRE) with contrast to assess tricuspid regurgitation severity and associated abnormalities.
Follow-up
1-year follow-up conducted via phone to inquire about patient's vital status, symptoms, and hospitalizations.
What Are the Treatments Tested in This Trial?
Interventions
- Cardiac Magnetic Resonance
Trial Overview
The study aims to evaluate how well cardiac magnetic resonance imaging (MRI) can determine the severity of tricuspid regurgitation in patients' hearts.
How Is the Trial Designed?
40 patients with moderate or more TR on echocardiography will undergo CMR/MRE with contrast to assess TR severity, and the associated extra-valvular cardiac and liver abnormalities. Patients will continue their clinical management by their primary physicians as per the standards of care. 1-year follow up will be conducted via phone to inquire about patient's vital status (dead/alive), symptoms and hospitalizations.
