Asymptomatic patients w/ severe primary MR preserved LVEF(>60%, LV end-sys dimension <40 mm [stage C1]) ▶️ mitral valve surgery is reasonable in the setting of serial imaging studies that reveal a progressive increase in LV size or decrease in LVEF (Class IIa)
4⃣/ Secondary MR:
Same as severe 1*MR (effective regurgitant orifice area ≥0.4 cm sq, regurgitant volume ≥60 ml, regurgitant fraction ≥50%).
✔️Therapies to reverse remodeling in HF (e.g ACE-I, ARBs, BBs, CRT & so on) 🔜 decrease MR severity!

6⃣/ Pathway for approaching patients with Secondary MR as explained in the flowcharts below.
