The concept of cone creation to treat isolated tricuspid valve dysplasia and the case of a double-orifice tricuspid valve

ObjectivesIsolated tricuspid valve dysplasia is a rare disease characterized by wide spectrum of possible anomalies. We describe the use Cone concept to treat patient with double-orifice massive regurgitation and severe deficit coaptation.MethodsThree adult patients congenital non-Ebstein anomaly coaptation deficiency underwent repair applying technique. In particular, we case symptomatic 21-year-old woman valve, right ventricular dilatation. The was transformed from into single-orifice valve. most superior orifice opened, tissue surrounding used extend leaflet inferior orifice. A created, ring annuloplasty stabilize result.ResultsThe discharged home after 7 days trivial residual no significant antegrade gradient. final height 2.8 cm. cardiothoracic ratio decreased 0.77 0.59 2 months, symptoms promptly improved.ConclusionsOver past years, have applied creation severely dysplastic excellent early results. One had adopted anyway. sacrificed, augment leaflets other created improve central good initial result.
