To the Editor:
I read with great interest the article by Chen and colleagues1 "Early and Medium-Term Results for Repair of Ebstein Anomaly." The results are superb, without hospital mortality and with improvement of the functional condition. The technique proved to be reproducible.
It seems from previous studies2 that the Ebstein anomaly is a combination of ventricular and valvular disease. This concept has led my group to develop the use of an associated bidirectional cavopulmonary shunt in severe cases.3
I was surprised by the preoperative right ventricular ejection function, which was normal in all cases except 1 in Dr Chen's series, without quantified data.
My first concern is to know what is meant by the right ventricle. Is it the effective right ventricle below the attachment of the valve or the right ventricle with the atrialized right ventricle? In most of the patients on whom my own group has operated, the right anterior wall was dilated and hypokinetic.4 I am interested to know whether this aspect was present in Chen and colleagues' series.1
The postoperative decrease of right ventricular ejection fraction could be due to the section of abnormal muscular trabeculations. It is in my mind an additional reason to decrease the preload of the right ventricle with a partial Glenn procedure.
