Mitraclip

Overview

Mitral valve regurgitation is when blood leaks backward from the LV into the LA due to insufficient closing of the mitral valve.

​

Symptoms may range from fatigue, shortness of breath, dizziness and palpitations.

​

Untreated severe MR can lead to excessive strain on the heart and heart failure.

​

Intervention may be needed in the form of open heart surgical valve repair or replacement, or by catheter positioning of a mitraclip.

​

A Mitraclip is a device that clips the edges of the valve togetheterto improve valve closure.
