Triangular exclusion technique in isolated posterior mitral valve leaflet prolapse for mitral valve repair

The prolapsed part of the posterior leaflet is inverted and excluded, not resected toward the left ventricle, and the margins of the prolapsed part are sutured to each other's using proline 5/0, extending from the posterior leaflet edge to the posterior annulus. Then the posterior annulus is reinforced with an annuloplasty band using a treated strip of pericardium. The determination of suitable ring size is subsequently predicated upon the assessment of inter-commissural distance surface area and the anterior leaflet, utilizing sizers that are correlated with typical mitral geometry.

Suggested Quality Metrics for Interventions for Mitral Regurgitation

1. Procedural success Absence of moderate or worse residual mitral regurgitation (on TTE within 30 days) Absence of stroke or mortality
2. Procedural effectiveness (1 year) Alive Freedom from moderate or worse mitral regurgitation Freedom from cardiovascular reintervention Freedom from NYHA functional class III-IV symptoms
3. Durability (5 years or later) Freedom from moderate or worse mitral regurgitation Freedom from mitral valve reintervention But our study limited to only 1 year follow up due to our academic authorities that will be added as one of the strong limitations of our study but we will mention at conclusion and recommendations to extend the sample size and follow up period of the operated patients till 5 years in the following studies that interested by the same topic
