Longitudinal Plication Technique in the Surgical Treatment of Ebstein's Anomaly

In Türkiye Ihtisas Hospital 57 patients with Ebstein's anomaly underwent surgical treatment from 1974 through January 1994. Of these patients 15 (12%) were treated with longitudinal plication. The mean cardiothoracic ratio was 0.68±0.25 and all patients were in sinus rhythm. There was no hospital mortality. Two patients were in low cardiac output and one had temporary atrioventricular block in the early postoperative course. The echocardiographic study showed improved results in 10 patients, mild degree tricuspid regurgitation in 4 patients and moderate regurgitation in one patient. All patients were evaluated clinically and echocardiographically. Mean follow-up period was 34.7 months. There was no late mortality. 13 patients are in functional class I and 2 patients in class II. Cardiothoracic ratio decreased to 0.60±0.15 (p<0.05). The majority of patients showed normal echocardiograms. We conclude that longitudinal plication can be an alternative repair in terms of improvement of clinical status.
