Medium-term results of percutaneous pulmonary valve implantation using the Venus P-valve: international experience.

Abstract

The aim of this study was to assess the international procedural and short-term to midterm experience with the new percutaneous Venus P-valve. Retrospective data of patient characteristics, clinical and imaging follow-up of Venus P-valve implantation outside China were collected. Thirty-eight patients underwent attempted Venus P-valve implantation between October 2013 and April 2017. Thirty-seven valves were successfully implanted during 38 procedures. There was one unsuccessful attempt and there were two valve migrations, one of which required surgical repositioning. The mean follow-up was 25 months with no short-term or midterm valve failure or deterioration in performance. Frame fractures occurred in 27% of patients. The cohort demonstrated a statistically significant reduction in pulmonary regurgitation fraction and indexed right ventricular diastolic volumes at six and 12 months. Implantation of the Venus P-valve has provided satisfactory short-term to midterm results with high success and low complication rates in an inherently challenging patient substrate.
