The Clinical Application Of Improved McGoon Mitral Valvuloplasty Technique In The Treatment Of Mitral Regurgitation

Objective:This study introduces a simple mitral valve repair technology that modified the McGoon technique,and evaluates its early and mid-term outcome.Methods:A pilot suture was sewed at the free edge of the prolapse leaflet between the two normal chordae tendineae and tied temporarily.If the saline test showed MR,the suture would be removed and repositioned;if showed no MR,the pilot suture would be tied securely,and additional interrupted sutures placed to close the edge of prolapse segment.Then placed this segment in the left atrium side,but not plicate the leaflet.And implanted a valve ring.Results:From January 2010 to December 2017,consecutive 103 patients with FED were treated with modified McGoon technique.Among them,81 patients underwent Modified McGoon technique alone;19 patients underwent Modified McGoon technique combine with other repair technique;and 3 patients changed to underwent MV replacement;the overall repair rate was 97.1%.Discharge ultrasound revealed mild MR in 7 patients and no/trivial MR in the rest patients.During follow-up(mean time,14 mouths),all 100 patients who underwent mitral valve repair were survived.No patient suffered reoperation for relapse of MR.We got 86 patients' ultrasound results during the follow-up in our center.The results revealed no/trivial MR in 63 patients,mild MR in 22 patients and moderate MR in 1 patientConclusion:The Modified McGoon technique is a simple and effective valvuloplasty for the MR caused by FED(expect A2).The early and mid-term outcome is satisfying.Objective:To explore the early-and mid-term outcomes of the modified McGoon technique.Methods:Collected 27 patients with mitral valve commissure prolapse underwent the modified McGoon repair technique from January 2010 to June 2017.All patients were diagnosed as Fibroelastic Deficiency mitral insufficiency.Compared the preoperative and postoperative and follow-up echocardiography result of patients,to evaluate the early-and mid-term effect of the edge-to-edge technology for mitral valve commissure prolapse.Results:No hospital deaths occurred during the perioperative period.No patient underwent a re-operation due to the recurrence of mitral valve regurgitation.The repair rate was 100%.Echocardiography revealed mild MR in 2 patients and no/trivial MR in 25 patients before discharge from the hospital.All the patients were survivingand no patient underwent a re-operation due to the recurrence of mitral regurgitationduring a mean of 17-monthfollow-up.The echocardiography results revealed no/trivial MR in 20 patients and mild MR in 7 patients.Conclusion:For the patients with commissure prolapse,the edge-to-edge technique is simple and effective.The early and mid-term outcomes are satisfactory.
