Letter to the Editor

Off-pump pulmonary valve placement

University of Nebraska/Creighton University, Joint Division of Pediatric Cardiology, Omaha, NE

To the Editor:

I read with great interest the article by Berdat and coworkers on off-pump pulmonary valve placement.¹ The authors present the results in 4 patients who underwent perventricular (transventricular) placement of a stented Shelhigh valve (Shelhigh, Inc, Union, NJ). The first clinical application of this procedure was published recently by Schreiber and colleagues.² I would like to congratulate the authors, who successfully used the perventricular technique for off-pump placement of the pulmonary valve.

The perventricular technique was initially used to close complex muscular ventricular septal defects, and the first report was published in The Journal of Thoracic and Cardiovascular Surgery by my colleagues and me.³ This technique has also been used to close perimemebranous ventricular septal defects.⁴

The initial experiment with the Shelhigh valve in a self-expandable conduit was performed in sheep by us and the results published as a book chapter in Transcatheter Valve Repair by Hijazi, Bonhoeffer, Feldman, and Ruiz.⁵ In this animal experiment, the Shelhigh valve that had been placed in the self-expanding Cook Z stent (Cook Inc, Bloomington, Ind) was placed with the help of a delivery gun into the right ventricular outflow tract of sheep. The approach was perventricular and no cardiopulmonary bypass was used. The clinical application of this approach followed this animal experiment.

I was astonished that none of our animal work with the Shelhigh valve or the perventricular approach was acknowledged by Berdat and coworkers in the case report.
