Abstract
The purpose of this study is to compare the early outcome of tricuspid valve repair using prosthetic ring annuloplasty versus suture annuloplasty.Methods:In the period between March 2016 and September 2017, 40 patients with severe functional tricuspid regurgitationsecondary to rheumatic mitral with or without aortic valve pathologydivided into two equal groups underwent open heart surgery at Kasr Al-Aini Hospital, Cardiothoracic surgery department. group (I) had tricuspid valve repair using suture annuloplasty, while group (II) had tricuspid valve repair using prosthetic ring annuloplasty. In all patients, left sided lesions were corrected during the same surgical procedure before tricuspid valve repair. All patients were evaluated thoroughly preoperative, intra-operative, and post-operative. Particular attention was paid to clinical findings of presence of tricuspid regurgitation (TR), itsnatureand degree, pre- and postoperative echocardiographic findings of TR, postoperative ICU events including the duration of mechanical ventilation, ICU stay, hospital stay and follow up of the degree of TR post-operatively. Results:Evaluation in these forty patients showed that there is no significant difference between results of suture annuloplasty and prosthetic ring annuloplasty early postoperative, while late postoperative echocardiographic studies had proven significantly better results with proshetic ring annuloplasty over the suture annuloplasty techniques in terms of low recurrence rate of TR among cases of tricuspid valve repair using prosthetic ring annuloplasty. Conclusion:we can conclude that the prosthetic ring annuloplasty for tricuspid valve repair is associated with better outcomes if compared with suture-based techniques, being a protective factor from recurrent TR after surgery
