Objective:

To present a case of simultaneous transcatheter edge-to-edge repair (TEER) of the mitral valve and K-Clip™ tricuspid annuloplasty in a patient with severe mitral and tricuspid regurgitation, highlighting its significance as a novel treatment approach.

Key Findings:

• Postoperative results showed significant reduction in mitral and tricuspid regurgitation, with specific metrics indicating a decrease from severe to mild regurgitation.
• At one-month follow-up, the patient reported no discomfort and exhibited mild regurgitation, with improved echocardiographic parameters.

Interpretation:

The simultaneous intervention effectively addressed both valve regurgitations, significantly enhancing the patient's quality of life as evidenced by symptom relief and improved echocardiographic outcomes.

Limitations:

• The case study is limited to a single patient, which may not generalize to broader populations and introduces potential biases.
• Long-term outcomes and potential complications of the procedure remain to be evaluated, necessitating further studies.

Conclusion:

This case provides a new treatment approach for patients with concurrent severe mitral and tricuspid regurgitation, suggesting avenues for future research and clinical application.
