Clinical outcomes of aortic valve repair for aortic regurgitation / 中华胸心血管外科杂志

ABSTRACT

Objective To analyze early-and mid-term outcomes of aortic valve repair(AVr) for patients with aortic re gurgitation(AR).Methods From April 2010 to December2013,94 patients underwent elective aortic valve repair(AVr) for aortic regurgitation(AR).There were 36 male and 58 female,and the mean age was(51.3 ± 18.0) (6-75)years.There were 2 patients(2.1％) with severe AR,88 patients (93.6 ％) with moderate AR,and 4 patients (4.3％) with mild AR.The total number of the aortic valve lesions were 110,including 31 for annnlar dilatation,1 for leaflets fenestrations,1 for leaflets vcgctation,61 for leaflets prolapses,11 for leaflets calcification or thickness,and 4 for commissure fusion.We performed the annuloplasty for 32 patients including commissure plicature for 20 patiengs,subcommissural annuloplasty for 11 patients,valve-sparing aortic root replacement for 1 patient,and the valvuloplasty for 78 patients,including leaflets plicature for 2 patients,commissure suspension for 59 patients,leaflets shaving for 11 patients,commissure resection for 4 patients,leaflet patch repair for 1 patient,and leaflets vegetation msection for 1 patient.The concomitant procedures include coronary artery bypass grafting for 18 patients,mitral valve replacement/repair for 72,tricuspid valve replacement/repair for 75,congenital heart disease correction for 27,and ascending aorta plasty for 9.Results There was no case with aorta re-erossclamp,or aortic valve replacement due to AVr failure.In-hospital mortality was 4.25％ (4/94).Postoperative echocardiography showed 75 patients (79.8％)with none AR,13 (13.8％) with mild regurgitation,and 6 (6.4％) with moderate regurgitation.There was no severe AR post operative.AR gradient reduced in 94.7 ％ (89/94) of patients.The mean follow-up period was (30.6 ± 10.4) months,and the overall survival and the freedom of re operation for aortic valve were 100％.Conclusion There was good early-and mid-term outcomes of aortic valve repair for patients with aortic regurgitation.
