In this issue of Cardiology, Legius et al. [1] report their experience in 49 adult patients (>16 years old) with Eb-stein's anomaly. The mean age was 29 years. Interestingly, only half of these patients (n = 25) underwent tricuspid valve surgery; the others were observed and/or managed medically. Primary tricuspid replacement was necessary in 9 of the 25 patients undergoing operation, and redo tricuspid surgery was necessary in 8 subjects. Arrhythmias were frequent; supraventricular tachyarrhythmias were most common, and ablation was performed often. Indications for surgery are not detailed - 'severe tricuspid regurgitation' was their most common indication. Cyanosis was the only symptom described and was present in a few.
