Association of edge-to-edge repair to de vega annuloplasty for tricuspid incompetence

Abstract

Background. We aimed to analyze whether association of edge to edge repair to De Vega annuloplasty would result in better results in patients with severe TR. Methods. Fifty seven patients with TR≥3 were randomized to undergo modified De Vega alone (group D, 28 patients) or associated with edge to edge repair (group E, 29 patients). All patients had preoperative and two postoperative (early and mid-term) echocardiography. The tricuspid regurgitation, diameter of tricuspid valve annulus, pulmonary artery pressure and right ventricular EF were recorded. Results. Early postoperative echocardiography indicated less residual TR in group E while other parameters were comparable. The mean follow-up period was 28.2±5.4 months. Mid-term postoperative mean TR was 1.9±0.8 vs. 1.0+0.4 (p=0.0384) indicated less redevelopment of TR in group E. Additionally TVA re-dilatation was found more prominent in group D. One patient in group D underwent operation for recurred TR. Conclusion. Our results suggested that association edge-to-edge technique to De Vega annuloplasty has resulted in reduced residual TR and less incidence of recurrence of TR and TVA dilatation.
