Atrial functional mitral regurgitation (AFMR) is common in heart failure. Severe tricuspid regurgitation (TR) is often seen in these patients.
Research by Dr. Kaneko and Dr. Kagiyama investigates the effects of severe TR on AFMR outcomes. Their study was published in the European Journal of Heart Failure.
The study analyzed 792 AFMR patients from the REVEAL-AFMR study. Researchers categorized them by the presence of severe TR.
Results showed 14.9% had severe TR. These patients were older, had advanced heart failure, and more atrial fibrillation (AFib).
Key risk factors for severe TR included age, permanent AFib, COPD, and high right atrial pressure. AFib and COPD were particularly significant.
The study also found two types of TR: ventricular functional TR (VFTR) and atrial functional TR (AFTR). Both had similar prognoses.
TR severity, not its cause, influenced outcomes. Researchers call for more focused treatments for AFMR patients with severe TR.
The study highlights the importance of early detection of AFib and COPD. Preventive measures like smoking cessation can reduce TR risk.
These findings suggest better strategies for treating severe TR in AFMR. Further research is needed to improve patient outcomes.
