Abstract:
BACKGROUND: The Hetzer procedure for the correction of Ebstein's anomaly has the advantages of technical feasibility and incorporation of the atrialized right ventricle (RV) into the functional RV. MATERIAL AND METHOD: We preformed a retrospective review of 11 patients with Ebstein's anomaly and they had undergone a Hetzer procedure between March 2002 and December 2006. RESULT: The median age at operation was 19.8 years (range: 6 months~56 years). There were 4 males and 7 females. All patients showed severe tricuspid regurgitation (TR) preoperatively, and arterial desaturation (<95%) was present in 3 patients. The original Hetzer technique was employed in 6 patients with the Carpentier type A anomaly. In the remaining 5 patients with the Carpentier type B or C anomalies, valve competence was restored at the level of the displaced tricuspid valve mechanism. Adjunct bidirectional cavo-pulmonary shunt, or one and a half ventricle repair strategy was employed for all the patients. The median follow-up was 8.6 months (range: 0.8~51.9 months). There was no early or late death, and the immediate postoperative TR was trivial to mild in 8 patients. The median cardio-thoracic ratios on chest X-ray at the preoperative period and at postoperative 0, 1 and 6 months were 65%, 62%, 55% and 55%, respectively. CONCLUSION: The original or modified Hetzer procedure for Ebstein's anomaly shows excellent intermediate-term outcomes.
