A New Reconstructive Operation for the Tricuspid Valve of Ebstein's Anomaly
OBJECTIVES: We sought to describe a new technique for tricuspid valve repair in Ebstein's anomaly and to report early echocardiographic results, as well as early clinical outcomes. METHODS: From 2004 through 2008, 27 consecutive patients with Ebstein's anomaly aged 2 months to 17 years underwent operation for Ebstein anomaly with new method. Tricuspid incompetence was severe in 21 patients and moderate in 6 patients. The surgical strategies include palication of atrialized right ventricle to form the new tricuspid anulus in the normal position, mobilization of tricuspid valve completely which then be sutured in the new tricuspid anulus. For the patients with hypoplasia right ventricle, the Glenn procedure was also performed to decrease the right ventricle load. RESULTS: There was 1 (4%) hospital death because of ventricular arrhythmia. Early postoperative echocardiograms have shown good result. After operation, Tricuspid Regurgitation was mild in 22 patients and moderate in 5 patients. Median aorta clamp time is 65 Mins and median ventilation time is 6.75h. Except one patient with ventricular arrhythmia, there was no other serious ayyhythmia occurred after operation. CONCLUSIONS: The immediate outcomes of this new surgical techonology can have excellent results. From our point of view there has been an improvement in keeping the function the trcuspid valve in the operation for Ebatein’s anomoly. The follow-up is needed for evaluate the long-term function of trucuspid valve.
