Degenerative mitral regurgitation affects millions globally. Early diagnosis and treatments like surgery or transcatheter therapies significantly improve patient outcomes and survival rates.
Area of Science:
- Cardiology
- Medical Diagnostics
- Surgical Innovation
Background:
- Degenerative mitral regurgitation (DMR) is a significant global health concern, impacting millions and causing substantial disability and mortality.
- Timely diagnosis and effective treatment are crucial for improving patient prognosis and reducing the public health burden of DMR.
Purpose of the Study:
- To review current diagnostic and therapeutic strategies for degenerative mitral regurgitation.
- To highlight advancements in surgical and transcatheter interventions for DMR.
- To discuss the role of translational science in developing future medical therapies for DMR.
Main Methods:
- Review of diagnostic imaging modalities including echocardiography and cardiac magnetic resonance.
- Analysis of outcomes from surgical mitral valve repair, including minimally invasive techniques.
- Evaluation of transcatheter mitral valve repair/replacement in high-risk patients.
Main Results:
- Advanced imaging techniques enhance diagnostic accuracy and inform optimal intervention timing for DMR.
- Minimally invasive surgical repair offers durable results, lasting over 20 years.
- Transcatheter therapies provide effective solutions for select high-risk patients with up to 5-year durability.
Conclusions:
- Improving access to diagnostics and timely interventions like surgical repair is key to better DMR outcomes.
- Both surgical and transcatheter approaches offer valuable treatment options for DMR patients.
- Ongoing translational research holds promise for novel medical therapies to manage DMR progression.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
