Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Prior to surgical repair of a cleft MV, the degree of cleft edge fibrosis and retraction should be evaluated
A
true
B
false
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Transcatheter Edge-to-Edge Repair (TEER) of the mitral valve is used in the treatment of mitral regurgitation. TEER approximates the anterior and posterior mitral valve leaflets by grasping them with a clipping device in an approach similar to a treatment developed in cardiac surgery called the Alfieri stich.

Detailed explanation-2: -Mitral valve cleft (MVC) is a complete or incomplete cleft in part of the mitral valve due to congenital mitral hypoplasia. This condition may be present with or without other congenital heart defects (1). A cleft that is not associated with a septal defect is defined as an isolated MVC.

Detailed explanation-3: -Disease definition. A rare, congenital, non-syndromic heart malformation characterized by a slit-like hole or defect in one of the mitral valve leaflets, which is usually thickened and distorted.

Detailed explanation-4: -Introduction. The anterior mitral leaflet cleft is an unusual congenital lesion most often encountered in association with other congenital heart defects. The isolated anterior leaflet cleft is quite a rare anomaly and is usually cause of mitral valve regurgitation.
