Repair vs. Replacement >%80 of MR are repairable Produces more physiological flow states It better preserves LV function Less thrombolic events Betters survival Long durability Lower risk of endocarditis
4
Meta-analysis repair versus replacement for ischemic mitral regurgitation. 2011 9 study mitral valve repair for IMR is associated with better short-term and long-term survival compared to mitral valve replacement

Sizing Of Ring Degenerative normal leaflet: normal ring size Long Leaflet :Larger ring size Rheumatic & Endocarditis: normal ring size IMR : smaller ring size complete Rigid
47
Acute IMR Revascularizasion the same time Central jet and normal mitral aparatus-- Ring If not- MVR with Chordal preserving and bio prothesis
49
chronic IMR(CAD) 3+ and4+( repair) 2+ if lv dysfunction or incomplete revascularization(Repair) 1+ if fluctuant MR or intra op TEE :need to repair

mitral dilated cardiomyopaty(IIIb)
52
Techniques If central jet repair If eccentric or complex lesion replace If post leaflet angle>45 replace 2 size undersize ring Very low SAM risk Sadle shape ring better than flat ring
