22 Impact of Mitral Regurgitation on the Outcome of Patients Treated with CRT-D: Data from the InSync ICD Italian Registry A C Response to CRT at the 12-month followup visit Panel A: The clinical composite score (*P = 0.626), Panel B: The extent of LV reverse remodeling (#P = 0.343) Panel C: The combined clinical and echocardiographic criteria($P =0.577).

23 Cardiac Resynchronization Therapy as a Therapeutic Option in Patients With Moderate-Severe Functional Mitral Regurgitation and High Operative Risk Circulation. 2011; 124: CRT is a potential therapeutic option in heart failure patients with moderate-severe functional MR and high risk for surgery. Improvement in MR results in superior survival after CRT. Kaplan–Meier survival curves for time to all-cause mortality in MR improvers versus MR nonimprovers.

24 Mechanistic Features Associated With Improvement in Mitral Regurgitation After Cardiac Resynchronization Therapy and Their Relation to Long-Term Patient OutcomeClinical Perspective by Tetsuari Onishi, Toshinari Onishi, Josef J.

25 Mitral regurgitation (MR) and long-term outcome.
Mitral regurgitation (MR) and long-term outcome. Kaplan–Meier curves showing probability of survival, free from transplantation, or left ventricular assist device implantation after cardiac resynchronization therapy (CRT). Patients were divided by presence or absence of significant MR before CRT (A) and after CRT (B). Significant MR after CRT was strongly associated with less favorable event-free survival, which was further associated with MR grade (C). Onishi T et al.

Echocardiographic Predictors of Reverse Remodeling After Cardiac Resynchronization Therapy and Subsequent Events by Jae-Hyeong Park, Kazuaki Negishi, Richard A. Grimm, Zoran Popovic, Tony Stanton, Bruce L. Wilkoff, and Thomas H. Marwick Circ Cardiovasc Imaging. 2013,6(6): A multiparameric echocardiographic score is helpful in selecting patients likely to undergo reverse remodeling after CRT and predicts clinical outcomes.

28 CRT改善功能性二尖瓣关闭不全的机制很复杂,长期预后还不明确
t-LBBB→左室收缩不同步 t-LBBB→功能性二尖瓣关闭不全 t-LBBB≠二尖瓣关闭不全 CRT植入≠功能性二尖瓣关闭不全改善 CRT植入+早期功能性二尖瓣关闭不全改善≈CRT超反应 CRT植入+严重功能性二尖瓣关闭不全→预后不良

29 功能性二尖瓣关闭不全的外科治疗 2012年瓣膜病治疗指南:对于严重继发性二尖瓣关闭不全,LVEF<30%,优化药物治疗和CRT(如果适合CRT)后之后仍然有心力衰竭症状,可以考虑手术纠正严重二尖瓣关闭不全(IIb/C) 植入CRT如果无反应,可以应用二尖瓣夹技术,改善70%患者的心功能状态,增加左室射血分数,降低左室舒末容积 (J Am Coll Cardiol. 2011,58: )
